[ARC5] Transistorized ARC-5 Receiver

[MICHAEL ST ANGELO]

I wanted to operate my receiver in remote spots and wanted it self-contained as well as lightweight so I chose the solid state path. Besides I got the set without tubes.


I operated it from 8 AA cells but it could have probably worked from a 9 volt battery.


It had a product detector taht support sideband as well as CW reception since I was intending to make downconverters for HF bands but it never came to pass.

B+ is a stack of seven 9V batteries in my case.  I have taken such a config to the field and it works great.  Alternatively you can stack two gels for filament and run the B+ off the 28V too.  Gain would be lower and the osc may or may not reliably start (try different tubes).  There is a simple reversible screen divider mod that helps with B+ that low.
