Re: [AMRadio] Hallicrafters WR-600

Bob, According to Chuck Dachis' "Radios By Hallicrafters," The WR-600 is identical to the S-120. You can find a manual for the S-120 on BAMA. Go to http://bama.edebris.com/manuals/hallicra/ and click on s120, fourth down in the third column. 73,

[AMRadio] Input to IARU Region 2 Bandplan

In reading over the IARU Region 2 MF/HF Band Plan, Effective January 1, 2008, I notice that the only frequencies between 1800 kHz and 297000 kHz where DSB AM Phone is allowed are from 3600 to 3625 kHz, 3875 to 3900 kHz, 7100 to 7300 kHz, 14285 to 14300 kHz, and 29000 to 29300 kHz. My position i

Fair Radio Sales, https://www.fairradio.com/catalog.php?mode=view&categoryid=1420 , lists 4D32's for $17.50 each. Surplus Sales of Nebraska has them for $35 each. In the good old days when they were used in the Viking I and the K

[AMRadio] QRM fron Neighbor's Security System

Jim, You reported the following. "I have recorded a problem like this with an 8566B in peak mode. There is a continuous sweep from about 7.1mc to 8.5mc at a two to five second rate. Traced it to a neighbor who just installed the X10 security and home control system. It's using the spread sp

[AMRadio] Millen Coil info

Darryl, Congrats on finding some nice pieces of Millen gear. You might enjoy visiting the James Millen Society web page at http://www.isquare.com/millen/millen-page.htm . You would also be welcome to join the group. You could certainly use stand

[AMRadio] WE 303J

Jack, I don't have the info on the 303J you are after, but John, K2TQN, gave you good advice. If you can find just one coil winding with your ohm meter, that's the one to work with. You should be able to find the normally closed contacts, they will measure very close to zero ohms. Monitor th

Re: [AMRadio] Relay Rating

John, I can't beat Bernie's reply from experience, but I will add that 300 watts of carrier would produce 2.45 amps of current into a 50 ohm load and 2.04 amps into a 72 ohm load, so you won't be anywhere near "overloading" the 10 amp rated contacts. Personally I use a mercury-wetted relay t

[AMRadio] BC-610 Master Oscillator Stability

Bob, If I were lucky enough to have a BC-610 and I wanted vfo control with more stability than I could get from the BC-610's own Master Oscillator mode, I would certainly try driving it in the Crystal Oscillator mode with an external vfo. I've had very good results driving other rigs such as m

[AMRadio] R389 price

Bernie, There is a page I've got bookmarked that lists prices that things have sold for on ebay. The information may be several years old, but it's better than nothing. The site is http://www.aade.com/hampedia/prices2.htm . You can find R389 under t

Re: [AMRadio] AMRadio Digest, Vol 70, Issue 18

Bernie, My call, W8KGI, comes from Columbus. I lived there from 1970 to 1989 and worked for Bell Labs out at the Western Electric plant on East Broadway. I also shopped at Universal Service, and I even bought Gibby's 75A3 there when they were liquidating his gear after he died. Jim, W8KGI Sa

[AMRadio] RE 75A4 and other old gear

I have my original HRO-50, purchased new from Steinburgs in Cincinnati in the summer of 1950 (thanks, Dad!). It's had a few mods over the years, like a pair of mechanical filters and a tee-notch, a product detector and audio derived avc, saturated reactor filament regulation for the local oscil

[AMRadio] Elmac Bias Battery

I've long since replaced the bias batteries in my AF-67 and AF-68 with a Zener Diode in series with the 6L6 cathodes. You can get a 5 watt, 22 volt Zener, type !N5358BG, in an axial leaded package from Mouser Electronics for 32 cents each. It is Mouser part number 863-1N5358BG. A 5 watt, 22 v

[AMRadio] Replacing 866A's with SS

I would not be concerned about "higher voltage" problems when replacing 866A's or any other mercury vapor rectifiers with solid state rectifiers. The forward drop across mercury vapor rectifiers is about 11 volts. The forward drop across a single silicon diode is about 0.7 volts, and most repl

Re: [AMRadio] SP600 Question

I have started replacing caps in an SP-600 JX-17. I removed the crystal unit and was wondering if there is a need for it other than using crystals. In other words can I leave it out and if so what connections need to be made to bypass it. Thanks all, Paul WA3GFZ Paul, Be sure you

Per the page at http://www.traveldocs.com/th/embassy.htm , the Thai Embassy is in Washington, DC. They have Consulate offices in Los Angeles, Chicago, and New York. I, too, am curious as to why they want a Viking 1. I have one, on the air, with a pa

Re: [AMRadio] Relay Voltage ID

Robert, It sounds like you could use this relay to fill in for the non-working contacts on your existing relay. You just need to find out what operating current it needs and then configure the circuit in the 32V2 to feed it properly. I say "current" because relays, being electromagnetically dr

Re: [AMRadio] AMRadio Digest, Vol 66, Issue 4

Robert, If that Collins Parts lead doesn't turn up a relay for you, let me know. I'm a bit of a relay guru. If that relay went out on my 32V3, I'd probably substitute a trio of 48 volt, sealed contact, dpst relays, "new old stock" from my junk box. They would be functional replacements. I r

Re: [AMRadio] AM HAMCOM 2009

Bob, For those of us who can't make it to the hamfest, it would be great if the Powerpoint Presentation could be posted on the web where we could get a chance to see the gear. Jim, W8KGI There will be a power point presentation that was done by Tom NE7X on all the West Coast AM Operators

[AMRadio] Please look for JR3TVH on 40

Y'all, Tim, JR3TVH, has been trying to work the US from his QTH in Osaka, Japan, on 40 meters AM. I understand that Tim is working around 7160 +/- QRM starting at 1200Z. It would help if some of you folks on the west coast with a good signal and antenna looked for him. Thanks, Jim Hanlon, W
