Hi, Ron!
Yes, this is definitely a simple thing to try. Currently I have cobbled a 1.5v battery in there so I can tune and troubleshoot. If I ever get it working, I'm definitely going to try this. I don't want to send it out to someone and have that battery be a problem for them.
Currently, my I.F. is working ok. I'm injecting through a .01 cap to the grid of the first and second i.f., and they tune ok. RF is not going so well. The sensitivity is poor, I can't get the frequency dial to calibrate, and it just acts wiggy. For instance, I can set the tuning dial to 800 kc, dial my sig gen from 550 to 1500 and pick it up at 6 different places. Almost like the local oscillator is running spurious or some such. I don't know what to do. My 6A7 is pretty lame, and I have one on order, so I guess I'll try to give up on it until that comes in.
I'll bookmark this thread and let you know how your idea works if I ever get the set working. Right now, it doesn't look good.
Thanks!
Mike
