[Milsurplus] BC-348-R BFO problem

[Glen Zook]

One option to splitting the AF and RF gain controls is to remove the lower headphone jack and install the "new" control using that hole.  This does not require drilling a new hole and the control "lines up" with the other controls.  I did this to my BC-348 decades ago.

If, with if being the operative word you wanted to use a BC-348 for SSB operation best results are obtained by operating in MVC where the volume control acts as a RF gain control. That allows you to back the RF gain down and produce good audio. One of the many modifications for the receiver is to have two separate gain controls, one for audio and a second gain control for RF gain but that involves drilling a hole in the front of the radio. The stock receiver a great AM and fair CW receiver but considering the broad tuning and stock detector using the BC-348 for a SSB receiver is a little like putting a saddle on a cow, yes you can do it and it will work but what's the point when there are lots of good SSB receivers out there that will be far superior to anything you can do with the 348 unless you want to do a lot of work, like separate gain controls, product detector , improve the audio stage for more gain and use with a low impedance speaker and then
 maybe a huge knob to slo
w down the tuning rate, but after all that it isn't going to be much of a BC-348 anymore.
