Re: [Drakelist] Off topic:
Luther, Looking at the schematic, RL is not in a normally high power location, so most likely any pot which will physically mate up should work. But I like Mike would check the solder joints. Also check the switches. The SWR/power switch is also between the diodes and meter. An ohm meter on RL should be a quick check for it. An ohm meter from the fwd/ref switch center contacts to the top of RL should indicated if the SWR/power switch is okay. Let me know how it goes. 73, Ron WD8SBB --- On Sat, 1/16/10, Luther Nallie lanal...@hotmail.com wrote: From: Luther Nallie lanal...@hotmail.com Subject: [Drakelist] Off topic: To: drakelist@zerobeat.net Date: Saturday, January 16, 2010, 8:46 PM Now that I can get on all bands with my TR4Cw, my tuner went on the blink.

Re: [Drakelist] Off topic:
I am sorry I did not make it clear what the problem is on my first post. What is happening on the MFJ 941D is my reflected power is showing 3:1 on a dummy load and I checked it with a Bird meter and it's absolutely flat. Nothing happens when I try to turn the adjustment screw on the RL except if I go too far the SWR shows as a dead short. So it is showing some reflected power. I checked the connections as far as I could see and they look okay. What I would really like to do is change out the RL before I go any further and go from there. If anyone has a part number from a parts house, that would help me tremendously.

[Drakelist] TR4 and SB-200 Question
I have just recently purchased an extremely nice SB-200 with all of the Harbach mods installed, my question is this. With all of the mods installed which are mainly aimed at allowing the SB-200 to play better with today solid-state rigs, do these mods, in particular the Soft-Key mod now prohibit me from using my Drake TR-4 with the amplifier? I do realize one of my major concerns it to not overdrive the amp with the TR-4. After reading the suggestion which was posted a week or so back I think I may use the T-connector and a 100-watt dummy load setup to help solve the over driving problem. I am wondering if I should just use the ALC line and perhaps a foot switch on the amp. Any suggestions or feedback is appreciated. 73, Kevin - KG0MN E-mail message checked by Spyware Doctor (7.0.0.514) Database version: 6.14140 http://www.pctools.com/en/spyware-doctor-antivirus/ image001.gif___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
