Another entry into the analyzer battle, the C model covers 530KHz to 230 MHz. http://www.mfjenterprises.com/MFJ-259C_Flyer.php I wonder why it didnt go down to 470 KHz which would include the coming

There is a lot of CW and digital activity on 474.2 (USB). (Load wsjtx on your computer and see.) MFJ missed the boat. _________________ Topband Reflector Archives - http://www.contesting.com/_topband

I'm a VERY happy owner of the 3E model VNWA. I've made measurements on my 160M antennas with no difficulty, but I'm out in the boonies, not close enough to strong BC signals to have seen any issues.

Well, SMA is probably the most generally useful. With the adaptors in place, we just have to make sure that we include the adaptors in our calibrations. When it gets to be really "witchy" is when we

It all depends on the degree of precision that you need for whatever project you happen to be working on. I work all bands between 1.8 MHz and 900 MHz, and I occasionally need test equipment for all
