So I'm using a new 160M Loop, doubled from a previous 80M. Working very well on all bands including 60 and 6. Only issue is it's picking up a pretty high noise level on 40M. Varies S4 to 7 24hrs/day depending. Thought I would try one of these QRM E. Boxes. The MFJ 1026 one is a bit over $200 altogether .... thought I would try the original one which is only $50 on eBay. Operation and hookup is simple enough. No instructions at all. Have it hooked up correctly including PTT Kill to rig. There are numerous YouTube demos on the thing so I watched 3 of them. All went the same. Mine is apparently doing nothing. It is as if it's not there. It powers up - at the very least it should raise & lower RX power on the Main Ant. but it's not doing even that. No adjustment of 3 knobs has any effect. Did connect a temporary random longwire Reference ant.
I don't see anything else to do. Did I receive a lemon that's just not working?
