Delivered as ordered. Great product!!!

Well thought out product, big bang for the buck. I have not verified calibration but seems close and it has some adjustability in the firmware for those who need that level of accuracy. Well worth the price.

This did not include the pictured adapters, so I have no way to use this until I get some.

This meter is great, build quality is very strong. As far as alignment,(frequency accuracy) out of the box is close to perfect, only 000.001 mhz off, but u can correct it in the menu, great tool for the price

Upon arrival I tried to test the unit. The input was plugged into a monoband vhf radio that is known good. The output from the unit was a dummy load. I also had a vhf ht turned on to the same frequency as the transmitter just to make sure the tx radio was properly transmitting. When the tx radio was keyed the meter either showed no reading at all or an extremely low power reading 0.09 watts at a frequency above 400 MHz. I tried the test a number of times with the same results. Very disappointing. It has been returned

I bought this meter due having issues with a Latnex meter not correctly calculating SWR. Seems the Surecom is no different. Apparently, the newer models have this issue. Older models do not. Contacted Surecom about this and was a waste of time. ZERO help. Kept asking how many output watts does my NanoVNA put out. It doesnt put any watts out! Im not a radio expert by any means but I feel Im pretty confident I can read a cutting chart by a antenna manufacturer and can measure twice and cut once. I dont think I can get the SWR exactly to 1:1 on two different antennas. I think its an issue with the advertised frequency range. I checked it on a ham frequency of 146.52 and got a 1.72 SWR. Some of that could be the antenna isnt tuned for that frequency but it shows it can report something other than 1.0. This antenna was checked with a NanoVNA that was calibrated just prior to the test. Notice the difference in SWR between the SW-102 and the NanoVNA in the pics.

Really like it. Works great. Comes with pl259 adapters.

This unit is an easy-to-use instrument for measuring forward RF power and SWR for the most common VHF/UHF bands in amateur radio. My unit was built with N-connectors for Radio IN and Antenna OUT, but also came with two adapters for PL-259. At first I thought the device was defective when it would not turn ON, until I realized you have to press the ON/OFF button and wait until a timer (shown on the screen) decrements down to 0. Then it turns ON. An instruction sheet is provided, but it is intuitive to use without it. The default setting will measure forward RF power and SWR. An excellent unit for the budget-mined amateur.
