TRRS  

The output wattage is correct and accurate with the dummy load. The high SWR causes the false watt reading. Great video / review of this Surecom SWR device ! I want one :-). Thanks

I like how you spoke your callsign every time you transmitted into the dummy load lol

Try holding the black box like it says in the instructions. I get a lot better reading with SWR when I do that.

Neat little device for the shack. Thanks Tom. 73's

Neat lil' SWR meter, reasonably priced!

mine has a third bottom option , what does that do ?

The power reading is TOTALLY USELESS as Raymond stated unless you have a perfect match ! I just purchased one to measure SWR to get a ball park figure because its small and much more easier than dragging out my HP stuff. Like they say "you get what you pay for". TNX 4 the upload 73 N8AUM

Hi can i keep this swr meter in permanent situ with the external antenna connected?

Thank you, Sir.

Would you make video with your sw-33 with the VHF Frequency.. 140mhz to 174mhz

I have one of these and been using with good results. Put up a new external base antenna today. The SWR was 1.01 and 1.07 at the top of the GMRS channels. So I am very happy with that. While checking the Power wattage using this meter, have you compared the power readings from this meter to another one? The power reading using the dummy load works fine. When I put it on a radio that has a High and Low setting, the high should be 50 watts and the low at 5 watts on my radio GMRS 50X1. The high setting shows 15.5 and the low at 4.9. I can't seem to get the power to read 50 on this meter. The radio screen itself shows it is putting out high power but not sure really what it truly is.

just got one today works well found out my telescopic antennas have the best swr`s the factory ones suck. and after market antennas are ok.good little meter. but may want to do same test outside away from buildings.

I watched another video that this meter also showed high SWR. Are all the antennas de-tuned, or is the adapters and meter on a rubber duck causing the de-tuning?

Thank you for the positive review. I'm curious, would this equipment be suitable for testing both my 25-watt and 45-watt base radios, or is it designed specifically for portable radios? Your clarification would be greatly

Thank you for this video! If you read the instructions for the sw33 it states that you need to touch the box when testing. It brings it down to 1.01 without touching it it's 1.67. Did you try the same thing? Touching the Box while transmitting?

Thats why I dont use stock baofeng antennas, get and test a nagoya antenna they are much better. Thanks Tom

Would be interesting to see what its like on 2 meters with different antennas. Im tempted to buy one already!

How's the little meter reading? Im interested in one for my ht's and FT-817nd kit. Thx mike.

just got the Mark II of this same model (difference is the Mark II has ONE more mode: ref(lected) power, bottom horizontal segment lights up). I have 3 aftermarket antennas as well as the included antenna for my UV-5RIC (Industry Canada certified). The included antenna is the second version (tapers to the end, not like the first edition that didn't taper and was always reported as being horrible). Testing on the meter showed the included antenna

The manual says you should touch the SW-33 unit when you take a reading. Which you did not. This greatly affects the SWR reading.

The radiated power of the antenna may differ from the power input. With antennas like this, they can get a low swr by making them having a high loss. An extreme example, take a dummy load put a small antenna on it. I will give a low swr a good power input but very radiated power. This is in part how some of the antennas are designed so as not to damage the radio no matter what you do.

Same result of mine if am on UHF using stock antenna. Reading around 3swr. But if vhf I can get 1. Weird😅

I'm not sure you need to identify yourself when you use a dummy load, and when I test my equipment, I never bother with identification as most frequencies are unused in my area (Washington, D.C., suburb). I do a lot of scanning and there isn't anyone on the frequencies with the exception of a HAM repeater that's fairly popular. Oh, there are also two things about the SW-102, SW-33 and SW-33Plus. First, all of these meters test crazy high SWRs as is. The new SW-33/+ has three settings: 1) power, 2) SWR, and 3) reflected power. You also have to cup your hand around the meter and the radio when you take the reading. If you take the time to identify, your battery life will suffer. I generally transmit 3-4 seconds using a dummy load and five seconds using an antenna. And all of my Surecom meters test very high on antennas, even with Nagoya antennas! Power readings seem okay some of the time, then inexplicitly comes in very low. I'm hoping the 33+ does a better job. Again, try cupping your hand around the meter when you take your reading. It or may not help.

Yes my tests proved the same or similar results to yours. Basically the standard baofeng antennas are no better than coat hangers, the only usefull part of the frequency for these antennas was in the lower 2M 143 mhz range where i could get the swr down to 1.1- 1.5 apart from that its only good for receive for everything else and even more totally useless in the 430-520 mhz range. The surecom swr meter works ok, more than i can say for the rubbish baofeng antennas, i even tried a longer Nagoya knockoff and that was no better in reception or swr so that got binned straight away.

Interesting. When I was testing on my antennas, it triggered my paper shredder. That was weird.

Well now it looks like I have yet another bunch of tasks for my 3 BaoFeng radios...

Thanks for the great review! :) Obviously the antennas are not very efficient. Might make my own by calculating the wave length by 1/4, 1/2 , and / or FULL.... i remember the days of CB (27Mhz), and full wave length for that was 8ft 9inches, if I remember correctly....

Sir can you make a video that you are testing this surecom swr33 in an external antenna? Pls sir..thank you

Had some interesting results today after ordering a small mag mount from ebay for about $11. Model: UT-106 This little antenna with its tiny 1" mag mount actually surprised me with far better results than the stock baofeng antenna! SWR was down to 1.1 to 1.5 in the upper 150-170 mhz and although not great in the 477mhz range far better than the baofeng antenna. Using the SW33 meter . Although not a coclusive test as it was done under a carport but the results made far better sense than what i got from the baofeng antenna which was all over the place. FWIW :-)

just got mine; how do you know when it's fully charged?

Boy your voice went low at 4:43! Good for singing bass in a vocal group!

why dummy load is different than original antena? I mean the reading..

Did you even compare it to a reliable VSWR meter?.......I’ve got one of these and I don’t really trust its readings
