Re: [Drakelist] Drake 4 line crystals
I believe "Gold case" refers to the price of $45.00.

Re: [Drakelist] TR4C weak audio and poor sensitivity
Well guys, I found the trouble. I decided to try inserting a signal with my sig gen and started with the antenna jack, then went to the external antenna jack, then went to the fuse lamp socket (tested lamp removed) on the relay side, then to the T-9 side, VOILA! Good strong signal S9+5 at 50uv. I knew then that it had to be related to the relay. I pulled the 6EV7 relay tube V19 and it tested good. I substituted another 6EV7 and the trouble went away completely. I put the original tube back in and still no trouble !?? Socket was in good shape so it's a conundrum. Hope it is not the T/R relay since I can see no way to remove the cover. Usually these relays are not used as a plugin so nothing to anchor down the base and rock the cover back and forth to pop it off. Bottom line, the rig works great. Still no doubt that the LSB filter is bad. Adjusted C130 best I can. It will be good enough. Can't afford to buy the INRAD filter set. Will still scope it out at the CXR BAL and at the filters. 73, Dick KF4NS St Petersburg, FL 33714 USA Keep The Glow!

That to me says it is likely to be one of the filters. Example: on 20M the trouble is on USB and on 15M it switches to LSB, in other words the trouble is always when the sideband switch is in the X position. All tubes have been tested and shorted/weak tubes replaced with new ones (pretested). The contacts of all switches and pots have been cleaned and the sideband switch tested for continuity. The 9mhz osc was adjusted for zero beat with C130 injecting a calibrated signal to grid 1 of V12. I have no idea if it may be an alignment problem caused by changing several tubes so please clue me in if that would cause this trouble. 73, Dick KF4NS St Petersburg, FL 33714 USA Keep The Glow! ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Re: [Drakelist] R-7
No, there is no provision for a fan on the R-7, and yes, it does get warm! Since they're still running 30 years later, it's probably not worth worrying about. I do like things running cooler, so a small fan blowing on the back panel heatsink certainly wouldn't hurt anything. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B, C-Line& TR-4/C Service Supplement CDs Hunter Ellington wrote: I have recently acquired a very nice R-7, but am surprised at how warm/hot the radio gets after about 45 minutes.
