Roadtalker 40 SSB Base 934.38270700

The seller says they can hear local radio traffic coming across loud & clear even with no antenna attached.

A little bit of info on this model:

These are great radios. I have one. These were sold around 1978, built by Hitachi for Sears (and JC Penny as well). Great build quality and easy to work on. The VFO is based on the SM5104 PLL chip. There were lots of mods in the old magazines for these radios. Plenty of room inside too.

The internal 13.8VDC regulated PSU is a little on the weak side and most people reccomend using an external supply. I rebuilt the supply in mine and it does 4w full modulation AM and 12w side-band nice & clear without dimming the meter backlight. If you're gonna "Peak & Tune" it for barefoot transmitting, you want an external supply. Sears uses the same mic connector (5-pin DIN) & pinout as Radio Shack. You can get an aftermarket mic for $20 or an adaptor to 4-pin for $10.
