2950/2970DX 15 meter mod

Hiya Wire Weasel!

While there probably is a link on how to do this mod, I actually discovered this one on my own, on my old 2950DX (the bi-polar transistor version). Here's how you do it.

Remove the bottom cover and turn the radio so the front of the radio is facing away from you, upside down. If you look where the CPU is at, you'll notice 4 pins in a square configuration, right above the place where you plug in the "key" for the channel expansion (see photo, sorry for the grainy pic). Place a jumper on the RIGHT set of pins. Turn on the radio, and it should pop up at 21.000 MHZ. Also, if you play around with the + and - split feature on the radio you can go as low as 18.6 MHZ and as high as 36 MHZ. But this mod alone will get you 21.000 MHZ to 29.699.9 MHZ continuous coverage. It will also transmit in all modes at reduced power at 21.000 MHZ, I checked it on a dummy load.

Enjoy!
