Scott. You are trying to set the signal generator and the pitch control to the xtal frequency simultaneously. The remarks column gives the procedure. The sig gen will peak at xtal freq, the pitch will

Yeah, thanks for the reply. I am really interested in your ongoing experience here. I've measured actual IF crystal resonances of crystals both in and out of the radio - usually by sweeping them with

I'm a little foggy on this, but I believe you are supposed to set it for highest output I think ________________________________ Sent: Thursday, November 3, 2022 2:26 PM To:

So – this is something I’ve gone over and over again in the alignment instructions and I can’t find an answer. Hallicrafters wants the IF aligned to the frequency of the crystal (which is almost

My perspective is somewhat odd – every boat anchor I restore is a learning experience. I tend to fuss around with things not because I’m unsatisfied, but because I’m curious. On the crystal –

Ya,, this sgt Friday shifted up to 88+megabicycles before terminating the transmission. Friday came in on a big old Slivertone which had 78,58 etc tubes , no octals, but never came in on my home built

HI Richard; he didn’t say anything about what goes on for other stations .. But if only at the end of the dial , what you propose is possible i guess, if cap can go over the hill .. Don VA3DRL Sent:

De Sergeant Friday I liked Dragnet better when it was on AM radio. Not many will remember this.

The crystal should be held firmly in place. Sounds like some thing is missing inside the holder.

Take this with a grain of salt, but I believe I read somewhere that someone has taken these apart and cleaned them, with good results I was researching my SX-62 I was reading up on this, but my

If I understand the question the double.tuning is at one frequency at the bottom of the FM band.? It seems to me that an IF problem would show up on all stations.? A problem with the oscillator

IF might have two peaks and capture ratio can “lock” onto either ..depending on cap position Don VA3DRL Sent: Wednesday, November 2, 2022 6:50 PM To: [email protected] Subject: Re:
