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 sensitivity of the R-4C, but most all of us are limited by external noise levels well above the MDS of the TR-7, with the exception of 10M, maybe... The block diagram is quite different, with the '7 having a 48 MHz first IF before the similar 5.645 MHz IF of the C. The IF filters are 8 pole crystal filters, same as the C-Line. The PBT and RIT compensate in large part for the transceiver syndrome limitations, and the RV-7 Remote VFO is a handy accessory, allowing you to operate separate or transceive with either PTO. There have been some improvements, with everything reasonably settled after the 6-7000 s/n range. SOME units have a click on CW, but simple mods have been worked out. SOME of the PA blocks have a few quirks, but again mods have been worked out. The TR-7A started around s/n 10 - 11000, but is identical to the TR-7 with the exception that a 500Hz CW filter and the Noise Blanker were standard on the A. A resistor was included to enable the AM, similar to the R-4C, and an extra phono jack was included on the rear panel as an auxiliary microphone input. There's probably more, but Jim will cover those. :-) All in all, a very nice radio, but it does NOT glow in the dark like the C-Line! 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line TR-4/C Service Supplement CDs www.k4oah.com AirRadio wrote: Dilemma time...

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 general coverage transmit/receive, the C line needs a lot of crystals or the FS-4 synthesizer. It would be best to compare the two alternatives, feature for feature, to see what matches your needs and preferences. The 7 line does not have the sticky paint in the later serial numbers. Cabinets can be repainted at Hartzell for $50 per piece. The 7 line is somewhat more stable than the C line, but unless you use the RV-75 digital VFO, it will drift to some degree also. Right now, I am down to three TR-7As, one R7A, and two R7s. All of them drift within specs, but they do drift. I've probably owned another 10-12 of them over the years, and none were ever rock solid as so many claim, for me; others' mileage may vary. But the RV-75 corrects the drift issue. Have done side by side comparisons between the C line and 7 line, and receivers aren't dramatically different. Than again, I'm not into weak signal work nor contesting, which are demanding applications. The comparisons were based upon properly aligned gear and I'm happy with both systems. The C line is sure nice in the winter where you get a little extra heat from the tubes, you can see the glow of the tubes in a darkened room, etc. You won't be disappointed with either, I hope, I'm happy with both. 73, Evan -Original Message- From: AirRadio airra...@dsl.pipex.com To: drakelist@zerobeat.net Sent: Tue, Mar 9, 2010 1:14 pm Subject: [Drakelist] C-line vs TR-7 Dilemma time...

[Drakelist] L4B, current for 24 vdc
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 have to start loading the circuit and see when the voltage drops off, but I'd rather know for sure, hi hi.

Seriously, a well-kept C-Line is a pleasure to operate and will prove itself well in a variety of conditions. The transmitter is a pile-up buster just barefoot, and the RX doesn't get in the way of the signals. For contesting, the TR-7 has become my go-to rig. You can't beat the convenience factor of not having to tune up when band-hopping. The RX consistently amazes me at the ability to juggle the PBT, RF Gain, and tuning to pull out weak signals between strong ones (although the same can be said about the R-4C). It's like that proverbial bunny, it jest keeps going and going. The full 7-Line twins has become my dream contest setup, as I have been learning some stupid 7-Line tricks that I have just never been able to do with other setups. But you (the OP) didn't ask about that. I find the R-4C to be just slightly easier on the ears than my TR-7, but that's just me. Both are excellent. In theory, the TR-7 should have better image rejection on RX than the R-4C. Not that I have ever seen any image problems with the R-4C. You can also get on 60 Meters with the TR-7, although I've never done it. 160 Meter coverage is built in, as well as the WARC bands as mentioned already. The C-Line is probably easier to repair and maintain for those who are not comfortable or knowledgable with solid-state or digital electronics. However, you don't need the fancy stuff to work on a TR-7 - usually all that is needed is a good digital voltmeter and freq counter. The TR-7 has the edge on modern conveniences and looks (not to say that the C-Line isn't attractive). Tought choice. I honestly don't know which way I would go if faced with the same question. I think I would end up finding a way to keep both. 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.

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.
