I can think of at least a couple solutions. One is to create a high external ALC voltage that decays 50 milliseconds after PTT arrives. It might be possible in some software to delay the tones, but I

Good point, and that may be a clue that you need a better fuse vendor, something not off shore. 73, Jerry, K0CQ _______________________________________________ TenTec mailing list TenTec@contesting.c

A MOV is far more effective if its located on the line side of any RFI filtering. That's because the the LC RFI filter acts like an integrator and slows the rate of rise and fall of the fast spike, b

In theory it would be possible, except the code I don't think is written that way. There are a couple things unique about the OMNI VII remote, one is that its ethernet and the other is that audio in

When the power connector and RFI filter are a module you can't get the MOV on the line side of the RFI filter nor do you have the RFI filter protected from burn down by a fuse on the line side unless

If "massaging" connector pins works, I'd suggest a quarter drop of DeoxIT on each pin before the massaging to make the "massaging" more effective and longer lasting. 73, Jerry, K0CQ _________________

If you look at a manufacturer's data sheet it will often give a rating for brass or copper corrosion. Mystik JT-6 number 2 is better in that regard than number 1. 73, Jerry, K0CQ ____________________
