[AMRadio] Moble AM... On 160?
This is am interesting piece of work: http://smg.photobucket.com/albums/v652/ranickel/Top%20Band%20Goes%20Mobile/ >From a 1963 Popular Electronics, I found it on the Glowbug mailing list. This might be a good "Starter build for a person like me, but the largest antenna I have is for 80 meters... How would one move this to the 80 meter band?

Re: [AMRadio] League dumps threat to AM
Paul, Thanks for blowing the whistle on this bunch of gangsters from Newington. I outright refuse to support anything that the (be)League(d) does anymore. Ed Hare was the only exception and he got trounced by the 'powers-that-be' that reign over the ARRgghhL. I've been reading up on the threads at eham.com and qrz.com, and there seems to be quite a number that believe this is the last straw with the (be)League(d).

Re: [AMRadio] Re: 4-400
Paul and the reflector, CQ magazine for November 1957, the annual antenna issue, has a very good and lengthy article on the construction of an HF amplifier utilizing two 4-400 A tubes. It uses a multiband switching grid input and I think the grid coil turret was the Harrington. It used a B&W final tank coil. I think there might have also been an AM modulator, I really don't remember for sure. My magazines are in Louisiana and i am in Colorado, otherwise, I could pass along the page number. 73, John, K5PGW No need to miss a message. Get email on-the-go with Yahoo! Mail for Mobile.

[AMRadio] Re: 4-400
I would guess the tube was nearing market during the Korean War. I know the early to mid-1950s is the time frame for the T-368 transmitter, specified with a 4-400 in the final. I have a 1957 Crosley T-368C that came with an old red script Eimac 4-400, JAN-type. The T-368 was the successor to the BC-610, so maybe some military historians on here know the development chronology. --Paul/VJB Don't pick lemons. See all the new 2007 cars at Yahoo!

RE: [AMRadio] Mfg date for 4-400 series
Thanks Barrie, that's just the info I was looking for. 73, Rick/K5IZ Rick: Not too far into the transmitting volume I find the 4-65, which has 5 pages. (Built a push-pull pair of these for 6M in the middle 1950s) Next is the 4-125A, with 3 pages. Next is the 4-250A, with 3 pages. Next is the 4-400A, with one page. Then comes the 4X500A, followed by the 4-1000A, which has three pages. I have five volumes of the HB-3. I have this particular book out at the moment because I've been helping a local ham with a 160M 813 project. 73, Barrie, W7ALW __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html 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 To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.

RE: [AMRadio] Mfg date for 4-400 series
Hi Barrie... In your HB-3, where exactly is the 4-400 data located? I found mine in the Transmitting volume and the other 4-tubes in last volume of the original set. I was also surprised to find only one (1) sheet of data. Is this consistent with your HB-3? Thanks, Rick/K5IZ I have an HB-3 here that shows a data sheet for the 4-400A dated 9-62. I also have an Eimac catalog from the early 1950s that shows the 4-400. 73, Barrie, W7ALW __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html 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 To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
