Thanks for the validation, Garey. I had to move on to some other things last night and so only got one chance to call someone after aligning. I do know that the rigs were WAY off before I did the transceive alignment, as I kept calling guys who were 20 over and getting no answer, so alignment was the first thing I thought of. I put them in SEPARATE and spotted them together and worked guys.
It was clever how that found that "feature" on 80m (which I had noticed before) to align the oscillators. The T-4X procedure of matching the tone on opposite sidebands wasn't doing it for me, which was making me think this receiver was out to lunch. I'll try it again after I get back home today. If okay, I'll figure that I can start working on returning the AGC back to stock and putting a headphone jack in where the PO put the pot for this handy-dandy variable AGC delay that messes up the AGC's calibration. Here's an interesting thought - and I haven't looked at the C-Line schematic yet (you know where I'm going...) I'm wondering how much surgery would be involved to lock the carrier oscillators on the older sets a la C-Line. I'm thinking it could be major -involving adding a wafer to the TRANSCEIVE switch. Adding spare RCA jacks would be relatively minor, as there's provision for them already (and so, no holes drilled). 73, Steve, W1ES/4 -----Original Message----- >From: Garey Barrell <[email protected]> >Sent: Oct 3, 2011 10:13 PM >To: Steve Wedge <[email protected]> >Cc: [email protected] >Subject: Re: [Drakelist] B-Line transceive alignment. > >Steve - > >It sounds like you are using the correct procedure.
