Converting the Ten Tec Model 150A to LO Operation on 80-20M

The Ten Model 150A from the factory was a 100 watt, 8 Channel Crystal Controlled Commercial Radio operating USB (LSB as an option) in the 2 - 12MHz range. The IF was at 12MHz.
I bought this radio for $100 and the 1st conversion was to use a remote VFO/control box that could select the 160, 80, 60, 40, 30 and 20M bands. I changed that over so that the Digital LO was inside the box and the band coverage was changed to 80 - 20M.
If you added the LSB option a second SSB filter was needed. The BFO was at a fixed frequency and to change from LSB to USB required two filters. (Drake style). Not finding a LSB filter I simply did a bit of magic by placing the VFO range so that a sideband inversion would result. I did this with a Bitx40 to give USB on 40M
An 8-position panel mounted switch selected the correct BPF and LPF. Since the radio stopped at 12MHz I had to change one of the BPF's and LPF's to cover 14MHz. Thank you, LT Spice!.

Thanks for the video. Conversions are fun, and the SI5351 can make them a lot less hassle, and allow conversions that previously just weren't worth the effort.

Great work Pete! Good to hear it in action. 73, Nick

Loving the content Pete!

Very cool!

Did you convert the "Channel" switch to control an audio band-pass filter (or some other kind of switched filter?

[@N6QW]

The location of the 8 channel selection switch is now the encoder location for the boring Si5351. There is no audio band pass filtering control. Certainly more things can be added but this is just a bare bones conversion. Pete

I wanted to see more inside.
