Fwd: Re: [drakelist] Tr-4 Low receive update
Matthew E. McNeely [EMAIL PROTECTED] made an utterence to the drakelist gang -- The switch is in the tranceive position and working correctly. Let me ask the obvious, and the only reason I do is because it's caught be several times. What about the tranceiver/mute switch on the left rear corner? Is it in Transceive position? If you have it locked on. take the lock and move it back and forth a couple of times. Mark At 11:37 AM 9/20/04, you wrote: Matthew E.

Re: Re: [drakelist] Tr-4 Low receive update
Don and Diana Cunningham [EMAIL PROTECTED] made an utterence to the drakelist gang -- Matthew, There is a #12 lamp, used as a fuse, in series with the antenna lead to the antenna changeover relay. It is located in different spots in different serial numbered TR4's, but some are on the bottom of the chassis, near the antenna connector. Others had it in the final compartment (watch for the high voltage if you have to go in there, hi). The pins on these bulbs can corrode (or the bulb be open) and you will get the symptoms you describe. Have you cleaned the pins on this #12, and better yet, checked it for continuity?? It will make receive VERY low, hi. 73 and good luck, Don, WB5HAK - Original Message - From: Matthew E.

Re: [drakelist] Tr-4 Low receive update
Al Parker [EMAIL PROTECTED] made an utterence to the drakelist gang -- Hi Matt, This isn't very technical, but -- my first TR-4, back in about 1974, was about the same. (I've had a bunch of them in various versions since, and should be more analytical -but--.) Back then as I remember, 10m wasn't much, but did come open some. My TR-4 was like yours on 15 10m, I just turned up the AF gain and worked a lot of folks. Maybe if I knew more then I might hv helped it some, but it did well, and the friend I sold it to worked the world with it, after I did. If you can hear some more antenna noise when you peak the RF Tune ctrl, then you're getting signals thru, and it's sensitive. It seems like you do hear signals, maybe the same ones you hear on the SS rig, but not as much S-mtr indication. Take a look at the manual and do the RF alignment in the order they recommend, you might peak it up some on 10 15. You can do it with the xtal calibrator signal, don't need any special eqpt. If you need more specific instructions let me know. 73, Al, W8UT New Bern, NC BoatAnchors appreciated here http://www.thecompendium.net/radio/ http://www.hammarlund.info - Original Message - From: Matthew E.
