I went to the headphone because I had to keep the receiver in a different room using a speaker. This precluded listening to changes as I made them. Turns out apparently, the fidelity was already lost so the changes made no difference. Great input! Is there no one near you who can help?? Not within a reasonable drive and then I wouldn't learn anything.

[AMRadio] FS: Huge Oil Caps, Drake B-Line, StarLite Receiver, NRI Tube Tester, BC-610 Crystals
For Sale. All prices plus shipping. Pictures available. Huge Oil Caps: I have 3 huge oil-filled capacitors that are genuine antiques. One made by Westinghouse, is dated 1927. These are about 15 inches square and 6 inches thick, excluding the large ceramic posts on top. They weigh 25-35 pounds each. Typical capacitance for each one is 4-6MFD at 4-6000 volts. They are not leaking. One may have some suface ruist on it in spots, the other 2 are clean. I'd like $30 each for these--about a buck a pound--if anyone wants them. Drake B-line: Drake R-4B, T-4XB with AC-4 supply and MS-4 speaker. I have tested these with mixed results. The receiver hisses, the filters work, the notch works, RF Gain and AF Gain work as they should. But the preselector only works on 40 meters and no signals are heard on any band. So it needs some attention. The transmitter tunes up and transmits SSB on 40 meters. I did not check for full output and I did not test any other band. Anyone buying this rig should expect to have to go through it and bring it up to spec. The front panels all look good, with some light stains that should easily clean off. The cabinets are all pretty scratched up but once they are on your radio desk shelf, no one will notice. The TX cabinet has some cut-out modification on the side with a connector, probably for attaching an external VFO. The RX has all of its crystals and two extras. The TX does not have any crystals in it (but you can just set it to transceive on the RX frequency which is the most common operation mode anyway. $275 Star Lite Short Wave or ham radio receiver, probably dating from the late 1960's. This looks like a Japanese atempt to clone a Hallicrafters receiver right down to the "S" logo (instead of "h") in the circle on the front panel that reminds me very much of the later Hallicrafters "H" logo. Anyway, this is a 5-tube set with BFO. It has mechanical bandspread which is slipping and will need tightened up. The tuning is working fine. It looks pretty good except for a white paint scuff on top and dirt all over--you can see coffee or something spilled on the front panel that needs cleaned off. It does seem to be complete and all original including the whip antenna clipped to the rear which is cleverly designed to mount on the one atenna wire screw and be held vertical by another clip. Untested and offered here as-is. $25 NRI Model 71 tube tester. This is an emission type tester with simple lever controls. It looks good inside and out, though the case covering is coming loose in spots and will need re-glued. Also, the roll chart is very stiff and needs loosened up and lubricated. As-is. $22 SCR-299/399 BC-610 crystals and storage drawer. There are 55 crystals here for the BC-610 transmitter and a rusty but restorable crystal drawer to hold them. The drawer could be from SCR-299 or -399. It was definitely made specifically to hold these FT-171 xtals. All the xtals say "In BC-610" on them. Some of the crystals are in the ham bands, as follows (in KC): 3995, 3955, 3850, 3825, 3807.5, 3700, 3580, 3570, 3556, 3520, 3510 and 1837.5. Most of the rest are in the range 2045 - 2557KC, though there are a few odd ones outside this range, but not in the ham bands. There are some duplicates, but not very many. The drawer may be rarer that the xtals--I really don't know. The rust on the drawer can be easily fixed with some simple restoration work. It's painted gloss black so no great color matching skills will be required to get it right. As-is. $50--less than a buck a crystal.

[AMRadio] Free Pick-Up: 7 Foot Black Rack
Free for pick-up in Pittsburgh, PA: An original 1930's Bud 7 foot black wrinkle enclosed 19 inch rack with nothing in it. It has a hinged rear door and is 17 inches deep from the rails to the back door. The rails are threaded. This came out of the estate of W8JLH a couple years ago and I no longer have room for it. Obviously, it's pick-up only in Pittsburgh, PA. Thanks for looking. 73, Don Merz, N3RHT __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [AMRadio] D104 element Rebuilding
Jim Candela wrote: Many years ago my Astatic 'Rochelle salt" crystal element died from prolonged exposure in my garage. The output from it was low, and distorted. With a burst of curiosity, and desperation I took the bad element apart. Feeling I had nothing to lose, I did just that yesterday but used sili glue to hold it all together. It was an interesting learning experience. Unfortunately, it didn't help my problem but mine was working; just not to my satisfaction. It still works about the same so I ordered two new cartridges from Mouser to see if it's me or the cartridge. I had been wondering how age/time/humidity could have the slightest effect on a quartz crystal millions of years old. Turns out they are not quartz at all but Rochelle salt which, like all salts, are very hygroscopic and turn to mush in time. js -- PHOTO OF THE WEEK: http://schmidling.com/pow.htm Astronomy, Beer, Cheese, Fiber,Gems, Sausage,Silver http://schmidling.com __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net

Re: [AMRadio] AM BANDWARMING
Why not start an AM calling frequency on 3865 Khz so that there can be activity 24/7 - something similar to East Coast Amateur Radio Service? It's all about presence. I for one will be operating from the Collins Radio Center on AM using the Collins 30K-1 on or about that frequency on the 15th of December.

[AMRadio] CRYSTALS FOR AM BANDWARMING ? ?
From: Donald Chester <[EMAIL PROTECTED]> > Frequencies I hear discussed are 3685, and down on the low end near 3610. FYI guys - I have crystals right now for 3615, 3645, 3655 kHz, 3686 and 3700 kHz I can try to get some made up for 3685 kHz if a lot of folks want them, but it will take a few months. Let's gauge the interest then. What about 3680 and 3685 kHz? Kind of like a mirror of 3880 and 3885 kHz - very easy to remember. 73 to all - Brian, AF4K __ AMRadio mailing list List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
