SS-10 SS10 Field Strength Power Test Meter Portable Field Strength Display 100K-3000MHz Field SS-10 Surecom SS10 RF Signal Strength Meter The SS-10 Field Strength Meter is ideal for reading relative field strength from your antenna. It is a compact unit that fits in the palm of your hand and can be taken anywhere. The best part of using it is that you now can tell if your antenna is radiating or not by simply holding the unit near your antenna and adjusting the sensitivity. Also, by taking measurements, you can find out relatively how strong your antenna field is. Operation The SS-10 Field Strength Meter is very simple to use. It requires no power because your antenna field provides the power necessary to run the meter. Simply raise the single whip antenna on your unit, stand several feet away, and adjust the sensitivity knob on the front, it’s that easy. .........

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) 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.
