Fred’s idea really resonated with me. My first SSB rig was an HW-32A, the 20 meter version of the rig shown above. If — as I suspect — these rigs are anything like the HW-101, they are not aging well. Heath’s drive for economy resulted in rigs that don’t hold up to well over time. I remember the sound of the plastic HW-101 dial clutch cracking when I pushed the button. <\/i><\/span>

<\/i><\/span> BITX40 Modules to the rescue! Put a mono-band board inside an old mono-band rig. There are a lot of possibility here. Some ideas: <\/i><\/span>

<\/i><\/span> — Put that Heath VFO to use. Maybe convert it to solid state. Or just put the LCD from an Si5351 in the window (Pete did this with an HW-101). <\/i><\/span>

<\/i><\/span> — Get the S-Meter wiggling. <\/i><\/span>

<\/i><\/span> — Keep the final amplifier circuitry in there and let the BITX drive it. This will give you a QRO option. (Uh oh, we’re in trouble again!)<\/i><\/span> <\/p>\n

Hello Fellows,<\/b><\/div>\n
Attached is a picture of my BITX-40 V3 adapted to a Heath kit Single Bander HW22. This is a work in progress but what a neat way to bring an old boat anchor into the present.<\/b><\/div>\n
<\/b><\/div>\n
The only parts of the HW 22 used were the front panel and case and knobs. Modifications yet to be incorporated include: AGC , a USB port on the front panel to access the Arduino, and a PTT\/CW mode switch.<\/b><\/div>\n
