## Description

Mcbazel SURECOM SW-33 Plus VHF/UHF 125-525 MHz Mini Two-Way Radio RF Power & SWR Meter: desertcart.co.uk: Business, Industry & Science

Review: Easy to use on handheld transceivers - As I was trying out new / better antennas on my Baofeng uv5rtp and I was thinking of making and experimenting with antennas of my own I chose this SWR meter to make sure the fitted antenna wasn't causing any damage to the output stages of the transmitter. It comes with a selection of fittings (SMA, PL-259 and BNC) to allow easy fitting to many radio units and a dummy load rated at 10Watts, - so suitable for a handheld unit. After charging its internal battery with a USB charger I put it to the test. It measures output power (up to 100 Watts) and vSWR as well as giving an indication of output and reflected power. Sometimes the figures on the display jump about a bit so I marked it down slightly on accuracy, but it works well and I have used it a lot. As well as home made antennas it was interesting to see how good some of the stock antennas perform. Many dual band antennas appear to be anything but, - giving a good SWR on one band and a much worse reading on the other. The SWR also varies a bit with location and standing next to metal objects does not do any favours in keeping the SWR down, I have a folding antenna and its SWR changes as it folds. Its SWR is perfect for VHF if the antenna is fully extended but poor on UHF. However if it is folded the SWR figures are reversed so now I always use it open on VHF and folded on UHF for best results (the antenna manufacturers don't tell you that, - but useful to know thanks to this meter) I do not own a digital DMR radio and the manufacturers claim it won't work with DMR. I do not see why it shouldn't and in any case most DMR radios have an analogue mode. Very pleased with this purchase so far and it has proved itself very useful when using different 2m band / 70cm band antennas.
Review: A superb and easy to use spot check device for aerial suitability and handset power levels. - A highly recommended tool for your radio kit bag. Probably the smallest combination power/swr meter i've ever seen, and this has no impact on how useable it is; far better handling for testing handheld radios - no faffing around trying to find a flat surface, and messing about with various long cables. Should definitely have one if you don't already, and test every aerial you have for your handsets. As some kit ones can be shockingly badly matched, and should be immediately disposed of on accounts of being at risk of blowing the handset, along with having poor range. Also quite effective at verifying handset output power, although you may find that the meter does not register a reading on extremely low milliwatt power levels, where possible test at higher outputs to get more all round consistent measurements. Also keep in mind particularly when measuring and confirming SWR that the test conditions should represent close to ideal typical environment use case - as antenna orientation and close proximity to metallic and organic objects can impact readings. Therefore preferably test in open space, with antenna vertical, and hold the meter with one hand to provide a solid ground plane. Otherwise, take test measurements taken under non-ideal circumstances with a pinch of salt, typically this results in SWR readings higher than might be expected. Also for those particularly enthusiastic about such things, and with a little more budget to work with, its also worth looking at a number of well regarded hobbyist Spectrum Analysers and VNA's which can give you further insight into how clean your handsets are, and more broadly how your aerials perform. However, as a bare minimum spot check device, you can't go far wrong with one of these :)

## Features

- V.S.W.R. Forward power direct digital readout, without any calibration.
- Maximum measurable power range up to 100W.
- Easy to install handheld Radio
- NOTE: NOT for the DMR digital radio. Please use correct dummy load. High power will damage the dummy load. Kind read the manual carefully before use.

### ⭐⭐⭐⭐⭐ Brilliant for my radios to see how many watts I'm transmitting and checking my SWR.
*by S***P on 2 August 2025*

Brilliant I use it on all my radios to see how many watts my radio is giving out on certain frequencies and I also use it to see what my swr reading is as well. Great and very useful if you are into radios (Walkie Talkies) like Quansheng, Radtel, TidRadio, Baofeng etc.
