Quick question. Is the MFJ series of SWR analyzer's the only ones susceptible to BC interference? Any issues with the Comet or RigExpert series? I know I can get a filter for the MFJ, but I don't nee

No issues with AA-54. Splendid unit. You might want to look at Sark 110, an extraordinary unit, well supported. Sold in US through Steppir. AG6CX Sent from my iPhone _________________________________
why not the SARK?! No BC issues here ... Gary K9RX Quick question. Is the MFJ series of SWR analyzer's the only ones susceptible to BC interference? Any issues with the Comet or RigExpert series? I k
Do you have a nearby broadcast station? I do not and the MFJ analyzer has worked fine for me at three different stations. John KK9A To: Richard Thorne <rthorne@rthorne.net>, towertalk-request@contest
This is exactly the right question. I live in the boonies, nearest AM broadcast is at least 10 miles away, and that only 1kW, So everything works for me. At the QTH where I grew up in WV I was less t
The issue with BC interference is going to be common to any analyzer that uses a broadband detector. The pricier RigExpert devices appear to be VNA type analyzers that incorporate "real" (i.e. select
The pricier RigExpert devices appear to be VNA type analyzers that incorporate "real" (i.e. selective) receivers and which would be immune to out of band interference. VNA type analyzers *still have
Thanks for all the information guys, W9PN lives few miles from me, he's having an issue with his MFJ-259 (pretty sure it's a 259). There are a couple broadcast antennas to his West and my North. One
Your mileage is going to vary. At Field Day everyone notices the RF getting into the analyzer from the other sites as a SSB or CW signal momentarily pegs the analyzer meter. However, with a constant

If you know what frequency the broadcast transmitters are on, and they are not "in band" of the freq/antenna you are trying to tune, you can use an ICE or W3NQN bandpass filter to try and eliminate t
Important distinction. The RigExpert and others like are vector IMPEDANCE analyzers. That is, they are a single port device. They can only measure S11 (and in some cases, do TDR). A VNA (Vector Netwo
