Digital Chinese RF Power/SWR Meters? & WHY PL-259 is BAD for UHF. 

Thanks for such an interesting, well thought out and well put together video. That little meter looks good for the price. I thought about getting one a few times but always put it off. I've got some cheaper ones and they're rubbish so this one is well worth it. Thanks for pointing the UHF issue on high power too! I hear a few amateurs talking about that and it shows in your tests. The spreadsheet is a great idea too, nice to see all the data together to compare. It's great you used high end radios to compare too! Cheers Paul, was well worth the wait!

Thanks for such an informative video! I appreciate the large amount of work it took to put together. This is the first time I heard mention of the working frequency range for PL-259. I am puzzled by why this is used in almost all commercially available GMRS mobile radios in the US.

Very nice review and demonstration. I received my SW-102 yesterday and look forward to using it, especially with my HTs. I do plan on making a ground plane plate to fit on the SW-102. Thank you for sharing.

Appreciate your work (not only this vid). Thanks!!!

Thank God! I'm sat in bed in my hotel room and was waiting for this! I'm going to watch now! 73

Thanks for the review. It looks a brilliant meter fir the money. It would be interesting to see how it's accuracy compares to a good high quality wattmeter such as a bird thruline. Enjoying your channel 😀

Worth staying tuned for the 'epiphany' moment.

vale la pena ver todo el video muy instructivo gracias por el esfuerzo

Hi, Thanks for the nice and interesting video. You did grate job. I also thought about getting that swr meter but always put it off. But now i should try that.. Thanks again. 73s 4S6RSP .

Awesome video.

Thanks for this video; very informative. One question: does the device need to be power on in order to pass the RF to/from the rig, or what I need to take it out of circuit? Thanks.

Where did you buy the Surecom SW-102 V2.06 ?

A very good informative video. Great!

Well this measure other people cb radio watts if im near thim in my semi truck?

Antenna MUST be vertical when testing.

So I have a couple of questions... 1.) Other than possible realities and such, can you test output wattage safely using an antenna rated for the power ouput or must a dummy load be used? 2.) Will one dummy do it all as in is there one rated dummy load that can safely test from zero watts to one hundred watts?

Hi, and thanks for this review! I have a question, at 14:22 what's the name of the connector, between the baofeng and the tester ?

Hi. I tested this item too in UHF with a 991a and saw too that using the same little coax with a PL and 1 1/2 foot long completly degrades the results. Connecting directly the antenna the 991a shows 45W and 1.35 SWR through one little coax and a switch but adding a second little coax and the Surecom gives a disaster,, SWR = 2 and the protection included in the 991a reducts the power to 15W. Always use a good coax, Aircell, .. in UHF and N connectors even if the length is only 50 centimeters.

6:56 You’re suppose to use the ground plate

Stupid question, I'm sure, but does the radio still operate if the meter is turned off?

My Surecom digital reader was a disaster. With my Baofeng UV9RPlus on one end and my Nagoya NA-771 on the other, I was getting 3.73W and an SWR reading of 3.58 with a fully charged radio and device. So I'm wondering if I need a ground plane? Surecom used to include one with previous models, but they stopped due to the cost. The company still recommends you use a homemade one. So did you use a grounding plane plate, or a grounding wire? My readings were not accurate, so I ordered a meter with a needle. Haven't gotten it yet, though. Also, Surecom recommends against using its little meter horizontally, but says to use it vertically with a ground plane for best results. But nearly all RU-vid reviewers use the meter horizontally. The instruction page shows it horizontally, then has one of those circles with a slash through it, to show it's the wrong way. Based on the results people get, it doesn't seem to make a dif.

The newer versions firmware is now v2.7

I tried adjusting frequency counter in that calibration menu, to get it to agree with the radio, but it doesn’t actually do anything :D

Проверил прибор Surecom SW-102 v. 2.06, я расстроен. Сравнивал с прибором Alan KW-520 и пытался калибровать. Прибор Surecom SW-102 вообще показывает не верные показания. Пытался калибровать, H VHF L VHF и H UHF L UHF, настроил мощность(50ом эквивалент) на определённой частоте VHF и UHF. На частоте на которой настраивал, мощность прибор показывает верно, но только на этой частоте. При переходе на другие частоты мощность вообще не верно показывает. Я заранее сделал контрольные замеры мощности на Alan KW-520 на разных частотах и записал их. SW-102 нигде мощность правильно не показывает, кроме частоты на которой калибровал. Про КСВ я вообще молчу, оно совсем не верное, ни на каких частотах. Для проверки КСВ подключал контрольные эквиваленты на 33ом(КСВ должно быть 1.5) и 100ом(КСВ должно быть 2) и близко нет, показывает КСВ 1.1 на 33ом и 1.13 на 100ом.... Прибор не пригоден для использования, хоть в помойку выкидывать что-ли... Я разочарован. Теперь вообще не знаю что делать. :-(

Does this work for CB radios ?

Why does everyone measure power with a dummy load? With a base antenna at home the results are different?

Why sell UHF radios and antennas with UHF socket rather than N socket if UHF socket is not good?

Hmm. I received this meter with PL259 connectors. Think I’ll return it.

Can it be used with am Cb

Does it work at HF?

To Poster: I'm sure this is cool as hell to somebody into it. You done a real good video explaining the subject with a clear in focus video. To RU-vid: I don't give a flying fuck about this. I finally watched it will you please quit fucking suggesting it to me.

ratings are ..... close. Have to remember it is a "cheap" meter. For the price, it will do, to make sure you are transmitting and the SWR seems to be very close. Here again, you are using a cheap meter. It will get you by but, not as your main meter for real antenna work

I sold mine. It was junk and mostly inaccurate.
