[Drakelist] A bit of shack cleaning - L7s, MN75s, WH7s, etc
I've decided to pare things down a bit here and am looking to sell both of my L7s, an MN75 and several of my WH7s. The amps are in great cosmetic shape, come with tubes but will require a PSU recapping. Was going to upgrade them with the Harbach boards but life gets in the way of projects. Thus, something for their new owner(s) to perform. The MN75 and the WH7s are also in great shape and work well. If you're interested in any of this equipment and want additional details, pictures, prices and shipping information, please contact me off-list. Thanks - 73 Fred, N8YX ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
[Drakelist] Thinking of buying Drake TR-4C
I am considering buying a Drake TR-4C for AM HF use. Is this a good choice? I’m not sure of the condition of the transceiver at this time. Gary Taggart KF0TW Sent from my iPhone ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Hi Gary, Sorry to so abrupt, but in a word, NO. These nice rigs were designed for SSB use, AM is a far afterthought to satisfy the folks of the day who thought AM was not really being replaced by something better. You run the risk of destroying your final tubes if you try to get more than the minimum power output stated in the manual. Sweep tubes were designed for intermittent (pulse, basically) use, with about 15 watts plate dissipation, meaning about 45-50 watts output is all you could safely get from a TR-4(any) on AM. And, it's not true AM either, so not great audio punch. Look elsewhere, it'd be more reasonable to consider a Heath DX-40, with a receiver of choice from the era to get the same sort of performance. Or a Heath DX-100, Johnson Viking 2, etc., for what was very common back in the days of AM, late 1950's - mid -60's, with a solid plate modulated 100+- watts. just my humble opinion, from an AM'er of those days (late -50's). 73, Al, W8UT www.boatanchors.org www.hammarlund.info There is nothing -- absolutely nothing -- half so much worth doing as simply messing about in boats Ratty, to Mole On 12/2/2012 12:43 PM, Gary Taggart wrote: I am considering buying a Drake TR-4C for AM HF use.

Re: [Drakelist] Thinking of buying Drake TR-4C
Exactly. While it has a decent receiver, a better combo, would be an r-4A or similar, and any ot the Tx's Al mentioned. AM is definitely NOT a 4-line strength...really is on the weakness side in my opinion. The R4a with the tube detector sounds better than the B version with solid state diode detector also.

Re: [Drakelist] Thinking of buying Drake TR-4C
Gary, I have several Drakes including a TR4C and NO without out modification they are NOT a good AM transmitter. IF AM is what you want to do, find a real AM transmitter such as a Johnson (Name your posion) I own a Johnson Viking-II for AM, or Heathkit DX-40, 60, 100, there are old Broadcast Transmitters available that won't fill your garage but provide 250 watts on AM etc. Some folks use yaesu's, FT-101's, I've been known to run my Icom-775DSP but Drake NO. I hangout on 3870KHz with the AMI guys and when someone comes on the air with a Drake its very noticeable almost looks like a sideband signal because of the controlled carrier signal. I hope this helps, John. -Original Message- From: drakelist-boun...@zerobeat.net [mailto:drakelist-boun...@zerobeat.net] On Behalf Of Gary Taggart Sent: Sunday, December 02, 2012 9:44 AM To: drakelist@zerobeat.net Subject: [Drakelist] Thinking of buying Drake TR-4C I am considering buying a Drake TR-4C for AM HF use.
