[AMRadio] WTD: DX-100 Manual and knob
I need a DX-100 manual copy. But weren't there different versions of this TX? Are the differences such that I need to make sure the manual I get matches the version I have? How do I tell which version I have? This one also has an unoriginal knob in the center below the dial. If anyone has an original knob, I could use that too. Thanks. 73, Don Merz, N3RHT
[AMRadio] WTD: Info On BW Model B Turret
The BW model B turret was apparently made before WWII. It has a multi-deck 4 position switch in a mount surrounded on 3 sides with coil jack bars for BW Bxx coils. This setup gives you both band switching and plug-in coils. I guess the idea is that coils for your 3 most-used bands could stay in the turret. So coil changing to switch bands is kept to a minimum. I think the B turret must be rated 100-150 watts. If anyone has an original brochure on the B turret or pages from a BW catalog that could be copied, I'd like to see that. Alternatively, if anyone has seen any published construction articles that use this assembly, that would be very interesting too. All I have now is the listing and photo in an old Radio Supply catalog. Any help appreciated. Thanks. 73, Don Merz, N3RHT
[AMRadio] Collins Collectors Association First Wednesday AM Night Jan. 7th!
FIRST WEDNESDAY AM NIGHT !!! Sponsored by the Collins Collectors Association. Cedar Rapids, Iowa (QRZ) - Wednesday Jan 7th on 3880 kcs at 7:30PM local East Coast time marks the start of the latest chapter of First Wednesday AM Night, drawing hundreds of vintage stations from across the country. The event is anchored by a tall ship AM station in each time zone. The East Coast will run for 90 minutes this month as a test. The remaining time zones will be an hour. Stations check-in using Collins and other transmitters with AM capabilities, new and old. The idea is to revel in this nostalgic mode, enjoy giving vintage equipment a run, and sharing some storytelling about classic vacuum tube homebrew and commercial designs. In months past, anchor stations have included those running the beautiful Collins 300-G, pictured below, as well as those running the amateur KW-1 and other noted models. http://www.amwindow.org/pix/jpg/300g.jpg LISTEN for these anchors and stop by to say hello, won't you? You don't have to be running Collins or vintage gear to be welcomed into the group. 8P-9P East Coast Anchor: Bill K2LNU (upstate NY) 8P-9P Midwest Anchor: Tony W9JXN (Illinois) 8P-9P Rocky Mountain Anchor: Jim WA0LSB (Colorado) 8P-9P West Coast Anchor: Bill, N6PY (California) comments please to [EMAIL PROTECTED]
[AMRadio] FS: Drake B-Line and SX-25
FOR SALE: I am getting ready to post these to eBay. But if you have any interest in them, please let me know in the next day or two. Drake B-Line. R-4B, T4-XB, MS-4/AC-4, MN-4 with original manuals. The MS-4 cabinet has some scratches on the side. But otherwise, this is one of the cleanest, nicest Drake B-lines you will ever see. It has been in my collection for about 10 years. I bought it from the original owner. It is in very good working condition, transmits and receives off of either VFO. The final tubes in it are solid. The only known problem happened recently and that is that one adjustment on the MN-4 has started to bind when the knob is rotated. I have not opened it up to find out why. With original manuals. $480 plus shipping for the whole rig. Hallicrafters SX-25 in fair to poor cosmetic condition. It's all there. The front panel has good silk screening. But the gray wrinkle paint on the front panel looks old and seems to have a very fine sheen of surface rust in spots. The top and sides of the cabinet are poor. One side has several bad rust spots maybe 2 inches in diameter. The top has several large stains but no rust. The louvers are present and have small rust spots on them. This radio has all original knobs, dials and meter. The dials both work. There are no unoriginal holes in the cabinet. But the rear chassis apron has several unoriginal holes for an SO-239 (not installed) and other unknown mods that do not seem to have been finished beyond drilling the holes. Internally, the chassis has light corrosion all over. All parts appear to be original. All tubes are present. The line cord has been changed. As-is. Untested. $65 Thanks for looking. 73, Don Merz, N3RHT
Re: [AMRadio] RF Chokes Needed
Dave I just saw your request for 30-k1 chokes. I have a couple of NOS National chokes which look an awful lot like the chokes used in the 30K. They have five pi sections though, not four.My 30k does have the five section chokes . I was going to use tlhese on a later project but I have enough of other chokes so I can let them go for $12 for the pair post paid. If you haven't found any others and are interested in them let me know and I will see if I can locate them. Maybe I can get a digi photo close up of them and send it so you can see for sure if it is what you want. 73 Wayne, N0TE
Re: [AMRadio] WTD: DX-100 Manual and knob
Just a clarification.the B model and they used 6146s as modulators in place of the 1625sNo, the DX-100B also uses 1625's as modulators. The Johnson Valiant uses 6146's as modulators...do not believe any Heathkit used 6146's as modulators. 73, Larry KC8JX --- Tommye Jim Wilhite [EMAIL PROTECTED] wrote: Don: The biggest difference in DX 100s is the use of a step cap in the output circuit like the Johnson Valiant used.

Re: [AMRadio] WTD: DX-100 Manual and knob
Actually, the Apache used 6CA7/EL-34's as modulators. The finals were a pair of 6146's. Alan WA2DZL On Jan 5, 2004, at 10:12 PM, Tommye Jim Wilhite wrote: This is correct.

Re: [AMRadio] WTD: DX-100 Manual and knob
One day I will get it right, the valiant and BW used the 6146s. Shouldn't try to think when I am asleep. 73 JPW - Original Message - From: Bob Bruhns [EMAIL PROTECTED] To: amradio@mailman.qth.net Sent: Monday, January 05, 2004 8:20 PM Subject: Re: [AMRadio] WTD: DX-100 Manual and knob I believe the Apache used EL-34s for modulators.

Re: [AMRadio] RF Chokes Needed
That would be fine, Wayne. Please dig them out and let me know more - size high, etc. What serial number is your 30K-1 and does it have the original output coils, etc. I believe that it is a series fed link coupled network.
