Subject: FT-209RH mods resolved

Some time ago I had tried the FT-209 mods as published in the Dec. '87
73 magazine.  It hadn't worked correctly, and someone on the net verified
that the jumpers listed weren't correct, but they'd forgotten the correct
jumpers.  Well I finally got around to doing the mod, and here are the
results.

The magazine article says to jump pins 1, 7, 9, 10, 11, 13, and 16.
In every 209RH I've opened, pins 1, 9, and 13 are already jumped.
Adding jumpers 7, 10, 11 and 16 allows "out-of-band" transmission.
But the receiver becomes thoroughly confused, and is not tunable.
The solution:  DON'T jump 11 and 16.

So the final steps are:
1) Add jumpers to 7 and 10.
2) Give the VCO can a 1/2 turn clockwise if you're moving to higher freqs.
3) Reset radio and reprogram rcv and xmit freqs, and rptr offset.

Hope this helps!
