I had one of those. I was getting some nasty RFI, which I eventually tracked down about a 1/4 mile away. Turned out to be a doorbell transformer. The homeowner yanked it out for me. That noise drove me insane, but the cancellator got rid of it. Took some fidgeting, but they do work.
Unless a buyer spins it off from MFJ, it goes down the same drain. Martin rescued a handful of famous product names as they reached senility. The drawback is that they all die with MFJ.
Martin was asked to sell Ameritron. He refused to break it off from MFJ...Sell all or nothing they were told...Sad...
I had many conversations with Rob Hood at Ameritron & he was very helpful. He would go through things to check so I didn't need to ship the amplifier back to them. He saved me lots of shipping costs. Great guy to chat with as well. If I found the issue, he would send me the parts as well so it was repairable. He would have made more money for them if I returned it but he did the right thing. Mike Enos was also very helpful before he suddenly passed away.
W8JI, Tom has stopped working on them because of the overwhelming amount of time and effort he has to put into them to find and correct mistakes.
