The SE-01 PTT works just like a normal PTT, push to talk and release to listen. There is no battery to charge and the SE-01 does not add any battery drain to your phone or tablet (the SE-01 has a small disposable battery you can easily change, but it will last from 1 to 2 years so it is very inexpensive to operate.) Using the SE-01 is super easy! Select 'External PTT' in your PoC App (not every PTT App supports external PTT, so check first.) Plug in the SE-01, and simply press the PTT to start talking. There is nothing to pair, nothing to charge. Couldn't be much easier Features: POC Audio Accessory Solution For Zello App on iOS and Android. Ear for hygeine & all-day comfort. 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 ).

FORWARD POWER MEASUREMENT 1. Set the Blue botton to the ‘POWER’ position. Set the Red botton ,‘FWD’ position. 2. Set the Radio transceiver to transmit and read the scale corresponding to the Power range selected yellow botton (10W, or 100W) REFLECTED POWER MEASUREMENT 1. Set the Blue botton switch to the ‘POWER’ position. Set the Red botton ,‘REW’ position. 2. Set the radio transceiver to transmit and read the scale orresponding to the Power range selected (10W, or 100W) VSWR MEASUREMENT Step 1 1. Set the Blue botton switch to the ‘SWR set’ position.Set the Red switch to the ‘SET SWR’ position. 2. Set the radio transceiver to transmit mode. 3. Slowly turn the CAL Control Knob clockwise until the meter point is at the ‘ CAL ’ position. This should be full scale. Step 2 Set the Red botton switch to the ‘SWR’ position while transmitting. The meter will now indicate the SWR ratio. CAUTION 1. Since the meter movement is very sensitive, avoid excessive vibration or mechanical shock to the unit. 2. The absolute maximumpower that should be applied to the meter is 100W. Also observe maximumpower inputs of 10W when unsing the lower ranges. 3. The transceiver and antenna connections to the meter must never be reversed.Always observe the correct connections to the transmitter and the antenna as 4. The meter has been carefully calibrated at the factory. Tampering with any of the internal circuitry or sensors may cause damage and will degrade the accuracy of the meter. 5. Do not expose the meter to excessive temperatures, high humidity, or strong magnetic fields. If you have related videos, please share with us, please contact us

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.

Connect the SMA to DUMMY Load Caution : Please use correct dummy load , High power will damage the dummy load. 1.2 How to measure SWR? All forms of SWR meters measure SWR, standing wave ratio on a transmitter feeder. Using SWR meter is relatively easy, but one should be able to interpret the results when using it. In general, VSWR and SWR are the same. When using VSWR meters to measure the the performance of a new antenna, always one should prefer to use up to 3W power and a clear channel. The following procedure can be used to use the meter. Push red button at two times to mode "V.S.W.R. meter " ,LCD display show Connect the SMA (mark TX) to Radio output . Connect the SMA (mark Ant) to ANTENNA When the the LCD show 1.00 to 1.50 , 1.0~ 1.5:1 mean the antenna is suit the frequency. When the the LCD show 1.50 to 3.00 , 1.5~ 3.0:1 mean the antenna is not good suit the frequency. When the the LCD show 5.00 to 19.99 ,5.0~19.99:1 mean the antenna is not suit the frequency. The VSWR meter is connected in the feeder from the transmitter to antenna. For the feeder convenience, SWR meter is located at the transmitter end of the feeder. This helps to monitor the actual VSWR values. One should know, where exactly SWR can be measured. There is always some degree of feeder loss, which has a major effect on the VSWR readings. Feeder loss absorbs power in both directions. When the reflected signal is reduced, there is a high level of feeder loss. The reflected signal gets reduced as a forward signal to the antenna, later it’s reflected back to the transmitter. Since the signal is reduced on its way to the transmitter, an antenna with poor match and high VSWR will be fine at the transmitter. Hence, when a feeder that induces a high loss is used, VSWR is good at the transmitter, but at the antenna, it may be poor.

By definition, VSWR is given as ratio of maximum voltage on the line to the minimum voltage. The same can be expressed in terms of forward and reflected wave voltages.

Q1) Hi SW-28HF is most inaccurate. I put 80 watts peak in and it displays >169. I put 2.8 watts in as a carrier and it reads 5.7 watts. Swr reads wrong too. On a resistive dummy load of 50.9 ohms it reads 1.2 swr. The display sometimes has artifacts until it is powered off and back on. A1) Please try to set the SW-28 as followings SW28HF rest data to FW 100 ,RW 100, Then Hold the menu, fast push peak botton 2 times to entre the menu mode set the select menu to [FW set 86 ], select menu to [RW set 96], long push menu change to" + "or " - " and then SAVE Q2) does SW-HF28 work with this Frequency is 27.385 MHz in SSB mode A2) It work 27MHz ,AM/FM mode , but not for SSB Q3) The ref (reflected power) didn’t have a decimal? The fwd displays a decimal? I’m talking about the digits under the swr, there’s no decimal So would 1000 equal one watt or ten watts. 0025 equal 1/4 watt? A3) It has a decimal point, which is at the front, because the reverse power value is measured more finely, so it is placed at the front. Q4) Can I check the output power without a dummy load? A4) It need to use a dummy load. Accurate power measurement requires a load. Connecting an antenna also allows power measurement, but requires counting. This is because the SWR must be 1.00 before the value is reached for accurate power measurement. Q5) What is the battery of SW28? A4) 502540 3.7V 550mah li-ion battery
