Q1) Can I also use SW-33plus on base radio like icom ic2300h? A1) It can use on sw33,but not include adator. Q2) SW-33 plus check the antenna and swr is 19. I rechecked other antennas and it's provided dummy load, 19. A2) Please make sure that the radio that you are checking is analog ? check sw33 use dummy load is 1.0 ,mean the meter is normal Q3) SW-33 plus good to measure mobile Radio? A3) For mobile Radio, we suggest using SW102 Q4) is it possible to test vehicular radios (power less than 100W) or just portable radios? In case yes, do you need a dedicated Load compatible to that power, correct? A4) Can test vehicle radio , but need to replace the adapter, high power dummy load Q5) Easy to use, results indeterminate The device was very easy to use. The results were anything but usual. I used a buddies swr meter and it was more accurate than this one i purchased. For my setup my buddies meter read swr of 1.75, this meter read of 3. It fluctuated up to a swr of 12. A5) Each radio will have some tuning errors. An SWR reading error of 1.25, plus or minus 1.5, is normal. If tested with a 50ohm dummy load, the reading is 1.0:1 - 1.05:1. Q6) I've read, "doesn't work with DMR radios" & that it "doesn't work in DMR mode". Simple question, Does it work with a DMR radio in set to FM mode? A6) SW-33 MarkII not support DMR radio Q7) HT VHF analog power out with dummy load and with antenna appears to match radio vendor specifications, although I do not have an in-line commercial watt meter to validate. However, on UHF analog (435.000MHz) the device displays an all white (pixelated) screen. See photo. This is consistent across multiple radios, power (3, 5, 10 watts) with native antenna or with the dummy load. Results in an inability to measure UHF power, vswr, and requires the device to be powered off and back on to recover. A7) remove the back cover, unplug the battery, and then plug it back in. Resetting the battery will resolve the blank screen issue.

Q1) Why SF401 frequency counter always show frequency less than it's actual? ( For example: installs on 433.000Mhz radio, counter shows 432.999Mhz) A1) Please go to [System] and set [Freq Offset] to adjust the deviation Q2) It can check UHF, but cannot check HF A2) Please try the followings * put the ATT button into left hand side * Make sure that the antenna is HF, as the antenna that we provide us dual band (VHF/UHF) only * please try to slant your radio to the frequency counter to make sure that the signal level in green area Q3) LCD display already show frequency or always receive signal before measuring will affect the device operation A3) Please go to Menu "RF Detect Level" and set 5 or above to solve the problem Q4) How far effectively can i detect a signal ? Close range as in 1-5 feet or can it work further like 5-15 feet ? A4) Radio cannot leave the frequency counter too far, make sure that the signal level in green area when you measuring. Q5) What is the small number after the CTCSS/CDCSS mean ? (see photo) A5) These number is for our technical use only Q6) Will the SF-401plus pick up Color Codes and Time Slots for DMR ham radio? A6) SF-401plus cannot pick up color colde and time slots for DMR radio Q7) What is the minimum digital pulse time required to register with the device? A7) digital mode for DMR radio only, not for other digital device Q8) How to close the attenuator?

Q1) Can SR-629 also just connect a PMR 446 radio device and use it as a repeater for PMR 446 radios, i.e. to increase the range? A1) It cannot be used, because the 446 frequency radio upload frequency and download frequency do not exceed 5 MHz. Q2) is SR-628 compatible for Motorola CM 300 as transmit? A2) Sorry, we don't have cable for cm300 Q3) Can SR-628 be used with icom 2200. Because I already have icom cable. A3) Yes, you can use 48-50-S repeater cable Q4) Why when my radio that transmits 8 watts is hooked up to SR-629, it retransmit power is only 2 watts ? A4) The transmission power has nothing to do with the SR 629. The 629 is just a switch to control the reception and transmission. The transmission power is determined by the radio. Q5) if SR-629 will work on Retevis L51 POC radio? A5) It can't work with Retevis L51 POC radio Q6) Surecom SR-112 to respond to DTMF commands. I have tried different radios, different commands, etc. but the SR-112 does not respond.Please advise. A6) Before connecting the repeater cable, please check all the Radio can be communicated. Then, check the repeater cable is fully plug-in between Radio and SR-112 device Please also check the volume, too loud or too small will also affect the DTMF Q7) Used SR-629 having problems. You can only listen to them, but you cannot send them back.I can only receive. When I press send, it doesn't work. I switch between a and b modes and then it doesn't send. (Use the network as a radio communication as a repeater as per the manual that he told me to do. I can send to the station pair and receive it, but the station pair I can't send back. That is the problem of using the box.) A7) The SR-629 has two modes: Mode 1: Radio A can only receive, Radio B can only transmit Mode 2: Radio A can both receive and transmit, Radio B can both receive and transmit Please check if device is selected into Mode 2? Also, we haven't tested the SR-629 for use with an internet radio. If it was purchased from your store, it should have used a 46-K patch cord, right? Since the customer is using an internet radio, we're not sure if the 46-K patch cord actually works with theirs (because we don't know if the earphone connector wiring is the same). The SR629 is designed for analog radio. It is not compatible with most network or digital intercoms. This is because when an internet intercom is in standby mode after pressing the PTT button, there is no noise current, which activates the 629 switch. Therefore, most network intercoms cannot be used with the SR629; only analog intercoms can be used. Q8) Can I use a TRRS to TRS cable from QYT8900 to Surecom sr628? A8) It can't and we dont have cable for QYT8900 Q9) Can SR-629 be used with a spender machine? A9) It cannot used with a spender machine Q10) Will these (repeater controller) work with Baofeng DM32? A10) All of our repeater controller do not support DMR digital voice processing.

Q1) Frequency counter in SW102 Meter show frequency less than it's actual? A1) Please adjust the Time Base in Menu 3 Q2) How to change the connector SO239 in SW102 Meter to N type ? A2) Please add a PL259 to N female RF ADAPTOR (Item Code: S052) Q3) Sometimes has dark screen, need to power on and off again A3) The flat cable maybe loose Q4) Has sound when shake the device A4) Screw inside maybe loose Q5) No menu 7 A5) SW102 meter in V3.7, there is no menu 7 Q6) What is the different between New and Old version of SW-102 SWR Meter ? A6) New Version of SW102 can check the Power Output more accurate and device can adjust the Power Watt mode automatically Q7) Power Watt below 0.6W , frequency counter result is not correct in SW102 Meter A7) For version below 4.3V, the Measurable power range: 1 - 120W(+-0.5%) Q8) Why the result is not same every time A8) Here is the correct using method of the SW102 SWR Power Meter. 1) When testing, the Antenna must be in vertical 2) There must not have object, metal reflecting If you want the result in same, then you should use dummy load for testing Q9) Can SW102 measure DMR radio? A9) SW102 is not for DMR Digital Radio, but SW102D can measure Digital Radio Q10) Why SWR result is different between SWR Meter and Antenna Analayzer A10) The SWR Meter is an inline device that relies on radio or external signal sources to input radio frequency, and then measures the ratio of forward power to reflected power in real time. The Antenna Analyzer, on the other hand, comes with its own low-power frequency sweep signal source and measures parameters such as SWR, complex impedance, and reflection loss at multiple frequencies at once. Since the Analyzer is usually tested on the bench, it does not necessarily reflect the state of the transmission line in actual operation Q11) I bought the SW-102S in August 2023 and now want to purchase the SW-102N. However, the product description on the Hong Kong website shows that the Efficiency % display has been removed. Does the current version still have this display? A11) The current SW102 version is V2.7. What are the differences between this and the August 2023 version? <---- Current Efficiency % Q12) Is a replacement battery available. Ours wont keep a charge anymore. A12) We don't sell batteries here, but you can ask the customer to search online to see if they're available elsewhere. The SW102 uses a 502540 3.7V 550mAh Polymer Li-ion Battery. Q13) Is the SW-102 suitable for VU models instead of HF models? A13) It depends on which model you have. *SW102-S/N : 125-525MHZ *SW102HF: 1.5-70MHZ Q14) I am specifically looking for this unit for GMRS base station and HT's, so 400-480mhz range (VU model), both for keeping an eye on SWR and radio equip TX output. Most of the time it would be used in passive mode, turned on only when i would routinely check output. This model, with rear antenna connections and front controls and display is perfect for my base unit cabinet design. A14) If you want to measure SWR and output power, you can use SW102, but it cannot continuously monitor Q15) Basically in SSB SW102HF shows values that are all out of whack A15) The SW102HF is not suitable for SSB operation. AM characteristics, also known as audio modulation (AM), are called amplitude modulation in Chinese. If the power is too low, speaking is required to generate power and initiate frequency detection. SSB = Single Side Band Single Side Band in Chinese. Simply put, it reduces AM by half. Our SW102HF is not suitable for SSB operation. Q16) After Multiple testing with different radio and antennas via uhf and vhf always the reading is 19.99 i already change the cable but same output… A16) To determine if there's a problem with the SWR ANT lead connecting to the antenna, or if there's a problem with the antenna itself, you can connect a dummy load to the SWR ANT position. If the reading is approximately SWR 1.0, this indicates a problem with the connection to the center of the antenna. The following issues need to be corrected: Is there a problem with the antenna connection to the walkie-talkie? 1) If an SWR reading of 10.2 is connected, you can analyze whether there's a problem with the antenna connection to the walkie-talkie. 19.99 indicates a problem, possibly an open circuit. 2) The antenna may be faulty and unsuitable for the transmitter frequency. 3) Check if the SWR TX and ANT connections are open. 4) Check if the connector is open. Q17) Is the SW-102N only compatible with products with an N connector? Can this model also be used with an SO239 connector? A17) If you want to connect with PL259, we have SW102-S model type which is SO239 Connection Q18) SW102-N Why I can't get it work on 220 MHz bands? A18) if check for the power transmission, the SWR meter mainly tests in VHF (144MHz) and UHF (430MHz) Bands. Othe frequencies may not can work about this function. But if checking SWR, it works for 125-525MHz Q19) I am specifically looking for this unit for GMRS base station and HT's, so 400-480mhz range (VU model), both for keeping an eye on SWR and radio equip TX output. Most of the time it would be used in passive mode, turned on only when i would routinely check output. This model, with rear antenna connections and front controls and display is perfect for my base unit cabinet design. A19) If you want to measure SWR and output power, you can use SW102, but it cannot monitor continuously, it only monitors once per transmission. Q20) I will try to make one custom ground plates for myself. Does it have to be a steel plate or an aluminium plate could also work? A20) A Ground Plane is a flat surface of ferrous metal (Aluminum, etc) Q21) A SW-102 with a ground plane won’t give more accurate SWR readings than a SW-33 Plus? The only difference is Tx-Transmission power (watts) reading? A21) Different antennas have different radiation patterns. Radiation may vary depending on the operating environment. The s w r data is for reference only. Q22) What the difference between SW102D and SW102? A22) SW102D can check DMR radio Q23) what is the difference between SW-102, SW-102HF and SW-102S? A23) SW-102 : N-connector, 100 - 520MHz SW102-S: SO239 connector, 100 - 520MHz SW102HF: SO239 connector, 1.5 - 70MHz Q24) I want to know exactly what connectors are on this sw-102. Are they N-type connectors or are they SO239 connectors? A24) We have two type of SW102 for selling: N-type connector and SO239 connector Q25) I have just received the Surecom SW-102HF. When I connect it to my transceiver and antenna I get really weird and spurious readings for SWR and Power. I checked the cables etc and found that the Antenna side of the meter is short-circuited. When I use a multimeter the resistance between the centre conductor and the shield conductor is zero - that doesn't seem right to me. A25) n the circuit, at low frequencies, a short circuit is normal. However, at high frequencies, it's not a short circuit. Therefore, using a multimeter to test for a short circuit is normal. The above circuit diagram can help you understand this Q26) Stopped working of my SW102.Worked at first but now display illuminates with no data.Is there a way to reset the SW-102 to resolve this issue? A26) If there is no display, press and hold the power button until it resets. Q27) With multiple radios and different antennas, VSWR always reads 19.99. Even with a 50-ohm dummy load, VSWR reads 19.99. How can I fix this? I am transmitting 6W on 446.000 with dummy load and still getting 19.99. A)27) Q28) Hello I already received the product Surecom SR 628 and connected it with my POC and UV5R. The controller is not functioning well, it sometimes work and sometimes not working - only blinking orange when the POC radio receive signal. i tried adjusting the POC volume but still the same the controller is malfunctioning, please see attached video A28) SR-628 not work for POC radio Q29) SW102 has failed after two months. Antennas tested right after purchase had SWRs in the range of 1.2 and 1.5. Retested those same antennas today and they show SWRs of 4.5-5.5 under identical conditions. In fact, all antennas show and SWR in that range. If I retest them with an analog Surecom RS-40 it reports proper SWRs. A29) Please use Dummy Load to check if the result is 1.0 ? Q30) Hello, I recently purchased your Surecom SW 102 SWR meter reader and have a question. It seems to be working however the frequency reading between the radio and reader are off by one digit as you can see in the image attached. I verified this with three radios and they are all off by +.001. Is there a way to correct this as my friends unit is dead on? A) Go to "MENU" , choose option 3 "adjust frequency" and then press "+/-" to adjust the frequency Q31) How long of a transmit is needed for the meter to accurately read VSWR and frequency? Would 0.1 second be long enough for an ~8W signal coming from a data radio or is a longer PTT needed like holding PTT for a few seconds? A31) Not more than 1 second Q32) How to replace the internal battery? A32) The outer casing needs to be disassembled with T6 screwdriver for replacement.

A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillation, or pulses per second in a periodic electronic signal. Such an instrument is sometimes referred to as a cymometer.

Noise Reduction Knowles Microphone. Front Facing PTT Button. Designed & Engineered in the HONGKONG This is our NEWEST invention for our customers wanting to use PTT apps on cell phones and tablets. Most cell phones and tablets do not support any kind of external Push-to-Talk (PTT) function on their accessory plugs,so users have either had to use the device screen or Bluetooth to make the PTT work. Sometimes it's not easy to push a PTT on the device screen, and Bluetooth can be inconvenient since it needs pairing, battery charging, etc. The SE-01 PTT solves this problem by having the computer software inside! (like phone calling, music playing, photo taking, etc.) Manual Wholesale Quotation Shopping Package Include: 1x SE-01 PTT Controller with Mic 1x 3.5mm MONO Earpiece Set-up wired accessories for Zello Android Depending on the Android device, you may need to disable Google Play Music under applications to prevent the headset hook from bringing up music. If you're using one of the Zello recommended accessories that function as a push-to-talk device, log into your management console and go to Settings > Android > "Enable Use specialized wired PTT speaker-mic or headset" and save. 1. Connect the accessory to your mobile device 2. Open Zello "Options" > "Push-to-talk button" 3. Select "Add Button" on the top right. You'll get a prompt asking you to press the desired button and it will be added as a "Headset hook". 4. Make sure the button is set to "Toggle mode" and that "Handle headset button when in the background" is enabled. Even though it's set to toggle mode, the accessory will work as a push-to-talk mode if it's listed as push-to-talk from the website. If you're using a device not listed, it will most likely only work as Toggle mode. iPhone/iPod/iPad Although Zello does have the option to map a headset hook from an Apple headset, it is not often reliable. Zello does not have the control to maintain the headset hook for PTT control, so the headset button will may sometimes trigger music. To prevent this from happening, make sure you don't have a music app in the background while using Zello. Connect your headset to your iPhone and then follow these steps: 1. Set push to talk button "Action" to "Toggle". (Zello menu>Options>Push To Talk button>Action>Toggle). 2. Make sure you have enabled "Headset/remote control" enabled. 3. Go to Audio settings and make sure you have "Mix with other audio" turned Off (Zello menu > Options > Audio > Mix with other audio > Off ).
