I was thinking of using model enamel and a toothpick, wiping away any excess with qtips. Mike. I use paint pens. They come in several colors and tip widths. I got mine from a local art supply store. Mine were made by the same people who make Sharpie marker pens. These are filled with enamel paint. -- Richard Knoppow Los Angeles WB6KBL dickb...@ix.netcom.com ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Best Offer I am the original owner so I know it's history. I had this unit working at my QTH for abt 10 years back in the 70s and 80s, then I went QRT until recently. The control box is in very good condition and was in storage in my attic for many years. The remote switch box sat outside in the elements all these years and shows it's age. I recently put it all on the work-bench and got it working again, but, it needs some work. I did replace the terminal blocks on the remote unit as they were beyond repair. The new terminal blocks are as close to the original as I could find. The switch contacts on the remote unit were cleaned with De-Oxit. I have done nothing with the control box, it is completely original. The only other parts replaced were the bolts and nuts to hold it to a pipe (the mounting brackets are original) and the grounding stud. I did have it working on the workbench, but when I put it on the tower, the motor would only turn if I gave the box a good whack, so it needs to be taken apart again and further restoration done. I lost the manual at some point, but good PDF copies are available, or I can e-mail one I found. I would rather see it go to a good home than just sit in my attic again. Contact me off list.

[Drakelist] Late R-4C 3rd Mixer Changes
Anyone who has had a late-production R-4C has heard the hiss when listening to a quiet band or a weak signal. Some folks say it sounds like bacon frying (Yum!) but to me it sounds more like the rain setting of one of those noise generators they sell at Brookstone that are supposed to put you to sleep at night. Searching through a lot of stuff, I've located two changes that do fairly similar things on the large scale, but require differing numbers of parts and time in which to do them. I knew there was a Sartori mod and - sure enough - I finally found www.archive.org and found the June 1979 issue of 73 Magazine. This is the change I remember doing back in the '80's. I remember that it helped quite a bit, but the receiver still was never really quiet. It changes the LO feed from the grid of V6 to the cathode. It also adds a series-resonant circuit at the plate to eliminate any excess 50 kHz crud from the output. I've wondered whether or not one could hear this but I suppose there can be products from all that crud that could get into the audible range. There's also another mod that's described on http://www.zerobeat.net/drakelist/drakemod/drmod40.html that involves fewer added parts and looks like an easier change, overall. It does the same overall feed change in that it moves the LO feed from the grid to the cathode, but doesn't use the resonant circuit. It also changes the limiting diodes to 1N4148's removes some capacitors and replaces them with either different values or jumpers. Besides erroneously calling out pin 1 of V6 as the old connection point, it's easy enough to follow. Has anyone out there tried both of these changes and, if so, which one worked better? 73 enjoy those Drakes... Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils. John Stark.

[Drakelist] Receive/Transmit Relay? Mute Problem?
Hi all, I have a Drake C-line rig that does not mute the receiver even though the transmitter is set to transceive. The unit has just been refurbished by one of the well known, much admired folks who do that kind or work so I'm sure it was in top notch working order when it was re-boxed and sent back to me via UPS, here on Vashon Island, WA. However, when I hooked everything up I found a big problem. 1. The receiver does not mute in any of the transceive modes. I get acoustic feedback of my voice if I transmit SSB. When I go to tune mode I get a loud tone (maybe 1,000 Khz sidetone?) in the speaker. 2. I've double checked all the interconnecting cables and had an experienced Ham double check my connections as well. I've also swapped a fresh cable into the mute cable position, as well as each of the other cables, as a process of elimination technique. 3. If I switch the receiver Function switch to external mute or noise blanker, the receiver mutes. However, even though the speaker is muted, the S-meter goes all the way over to the right to 60 decibels if in Tune mode. 4. We disconnected the receiver end of the mute cable and measured continuity to ground when switching the transmitter to Tune. The mute cable is not being connected to ground if the receiver is simply in the On position. However, the mute cable is being grounded if the receiver Function switch is in the External Mute or Noise Blanker positions. 5. During all this, we hear no clicking of the transmit/receive relay. What do you think? A faulty relay? Something upstream of the relay? Where do I start looking?

Re: [Drakelist] Receive/Transmit Relay? Mute Problem?
Rick, Maybe I mis-understood..but do you have the R-4C in EXTERNAL MUTE position?? It has to be. The TX should mut the RX in that mode. 73, Lee -Original Message- From: Rick Wallace rikw...@attglobal.net To: 'Drake List' drakelist@zerobeat.net Sent: Tue, Feb 7, 2012 10:32 pm Subject: [Drakelist] Receive/Transmit Relay?

[Drakelist] PEP mods for W7, W4, MN2700 MN2000
*Hi Guys, I just completed installing K4DPK PEP kits in the W7, W4,MN2700 and MN2000.* *I also put Blue LED's in the W7 and MN2700. The kits are extremely easy to do or I would have never been able to install them!! And they really work Great. Also the Blue LED's set the watt meter and tuner off really nice. You don't have to mod. these any to put the LED's in as they will lay on top of the meters inside the case and you pick up the voltage from the 9-12 volts to power the pep kit. I think its a nice addition to them but that's my opinion.* *K4DPK is a really nice guy a good friend and a straight shooter who is willing to help any one!* *Woody * -- * ** **Of **all the things I've L**ost, I miss my Mind the Most~~~* * If you forward this e-mail, please delete the forwarding history* *Thanks* *Woody* ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
