The Scout about which I have been enquiring showed a very unusual issue after I had replaced the final transistors (at the request of the customer). I did my usual ohmmeter reality check on all trans
You are right to warn about connecting an Eagle (or any other modern radio) to an SB-200 without a keying change. I am guessing that far more damage would be done to the Eagle than just to the keying
Lots of good suggestions already posted. Dont overlook the possibility of a heat-induced failure of a capacitor or anything else that could affect final amplifier or driver bias. Improper bias can ca
Ya know, it takes about 15 minutes to completely remove the front panel from an Omni VI. Take the panel off, spray the separated pieces with Windex, rub a bit with your fingers (no abrasives allowed)
The 5KP15A device is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Its job it is to short the supply
D116 is a 16 volt Zener diode on the I/O board, near the power connector. Its job is to prevent the radio from turning on if supply voltage exceeds 16 volts. Gary W0DVN
Added info: If D116 is shorted, it will not pop the fuse because it is looking at a 1K load resistor. If you did get a transient at the antenna, it is not unreasonable to think that D116 would fail.
Unfortunately Ten. Tec did not chose to offer pictorials of the boards. You are left to use your ohmmeter as your guide. Just connect one end to the fuse and probe around for things that look like di
I got your Omni V toady. What a packing job! Lets be clear on the issue: I assume it still has what appears to be a BFO issue. Please confirm this. 73 Gary
