[Drakelist] Power transformer in the R-4C receiver

Is it normal for the transformer to run quite warm after about an hour, even warm enough that you wouldnt keep your hand on it for more than a short while? Thanks Cliff VE7FD ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/m

After reading Max's inquiry this morning (PST) I've been stewing on what my 2 cents would be. But Jim said it all. Back in '82 I sold my C line to finance my 7 line purchase. I still have the 7 line and wouldn't give it up for any rig now offered (or offered in the past; I sold my KWM-

Re: [Drakelist] C-line vs TR-7

That's a point ... the TR-7 does not have a notch filter. I never missed not having one; however, using the R-7A in transceive with the TR-7 during the DX contest, I found myself often wanting to reach for the notch when I was listening on the TR-7 RX. A notch can be useful on SSB, and not just

[Drakelist] C-line vs TR-7

I agree with Lee. Worked the DX contest with the C-Line and L4B last weekend. Worked everything I could hear (even the 100 watt "weak ones"),1st or 2nd call. Lots of smiles. The band-pass and notch are a superb contest combo. What more could you want? The R4C beats my Icom every time.

The L4B uses a 24 vdc supply for powering the changeover relay. Does anybody have an authoritative knowledge of what the current rating is for the winding? I'm working on a project and would like to know if there is much of a reserve capacity on that winding. Lacking the specification, I'll h

Re: [Drakelist] C-line vs TR-7

Max, Well, I can firmly say, "it depends". I've had several B and C lines, as well as 7 lines. I currently use the 7 line and C line. It sort of depends on your preferences and needs. The 7 line is auto tune, while the C line is manual tune. The 7 line can be easily adapted to gener

Re: [Drakelist] C-line vs TR-7

Max - The TR-7 covers 1.5 - 30 MHz without extra crystals, and so covers the WARC bands, stock. The transmitter is limited to the Ham Bands, but most units out there have had the "General Coverage" modification already made. The receiver has a DBM passive front end, so not quite the sensiti

I have both. I bought the TR-7 new. Of course the TR-7 is solid state. I like them both. I think you mean R-4C and T4-XC rather then a TR-4C. I have both types of Drake too. If I were going to make a choice, I'd stay with the Drake. Drake is easier to fix and parts are more available. It
