|I bought this meter and a new antenna at around the same time. Had all kinds of random VSWR issues that made no sense. As in 5:1 to 3:1 depending on an antenna tuned and verified to be well under 2.0:1 and that includes from the end of the feedline. It wasn't until I acquired a good Antenna Analyzer and dummy load that I figured out the issue that was wreaking havoc and making an otherwise good meter a piece of junk. |
The SO-239 Receptacle for the PL-259 Center Pin are Over sized for the Antenna Connection.
Sloppy fit with every PL-259 I had on hand. Zero Resistance as the connector went in. BUT If I positioned the jumper just right or tweaked the cable, when connected, just right, my VSWR indication would make sense.
I plan to overcome the issue by Tinning the center conductors of the jumpers I use.
The other Receptacle for the XCVR side is slightly smaller and makes a decent connection.
You can actually look at the two of them and detect a difference with the naked eye. Maybe something happened in the Testing phase of the manufacturing process. Who knows.
Good meter otherwise, but if you get a unit with Cheap Sloppy SO-239's receptacles, hopefully you don't pull your hair out for too long before reading this review.
UPDATE 10/31/2021. I Tinned and groomed the PL-259 center conductor of my feed line to a perfect fit with the meters SO-239 receptacle. This meter has turned out to be very accurate on 2M thru 70cm in both High and low power modes. SWR reading are very consistent with my RigExpert AA1000. If you are having some flukey readings, I strongly recommend taking a look at those SO-239 receptacle sockets. 73/Mike KC7MAW
