[TenTec] Model 282 filter problem

[Silevitch, Michael]

Dear Clayton

Thanks for the offer. We don't have a 218, unfortunately. Still troubleshooting the 282.

Regards,
   Mike K1PEV

I have a spare 282 filter if it gets that far.  Would trade for a 218.

If so, remove the filter and, flatten the pin very slightly to obtain a tighter fit.  Be careful and don't overdo it.  If squeezed too much, the pin won't go down into the socket and will require filing off excess width.

I re soldered the entire board (the pins that plug into the radio were bad too) and it now works fine. A couple of the crystal pins would not reflow and I had to remove the solder and put a small wire around the crystal pin and connect to the foil to get them to resolder.

When the unit is plugged into its slot (on a Corsair) we get no response. Our next step is to test it on a network analyzer but I felt it would be worthwhile to also get inputs from people on the reflector.
