RE: [AMRadio] 450T amp
Am I missing something or is this a typo. Maybe the FCC has opened up a band down at 500KCs that I am not aware of. There is a lot I am not aware of these days!!

Mike WE0H WD2XSH/16 This, John, is just from a quick and preliminary search on 600khz... and the info is kinda dated, but... *Date Posted:* /Thu 23 Jun 2005; 9:22am/ *Author:* news *Subject:* New USA 600m/500kHz ham band permits close to being issued... ARRL Applies for 500kHz Experimental License Group of 23 sites seek to operate in 495-510kHz range. The American Radio Relay League announced that it filed an application for a two-year experimental license under Part 5 of the FCC Rules and Regulations, to permit experimentation and research between 495 and 510 kHz. Up to 100 watts peak transmitter power (20 watts peak ERP) would be used. Requested antenna heights range mostly from 12-18 meters; but a few are in the 22-33 meter range, and the Oregon site requests 43 meters. All are specified as non-directional. Modes listed in the application are 50 baud CW and PSK31. Dr. Frederick (Fritz) Raab, W1FR, will manage the project. Participating sites are located in Arkansas, California, Colorado, Illinois, Louisiana, Massachusetts, Minnesota, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Oregon, Rhode Island, Tennessee, Texas, Vermont and Virginia. This looks interesting... I'm searching for more data, and will send you in a private email. This bit should contain enough information so that others out there that have not heard about it can go in search of more info. -- 73 = Best Regards, -Geoff/W5OMR __ 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] 450T amp
eek, look what I started Jim...hi hi Sorry guys. Maybe we should tell them about the Part 5 license's, might get a few new operators down there. Imagine a kilowatt of AM on 1750 meters? hi hi...

It needs a little work, but I'm looking to sell this 450T amplifier, *with* a good working 450TL.

Re: [AMRadio] 450T amp
Any of the old ARRL of West Coast Radio books has schematics for triode amps. Here is a little something using a similar tube that was popular in the surplus scene many years ago : http://www.lakeerieba.com/6C21/KW_Amp.htm Although intended for slop applications, the above amp can be used to perk up your DX100 by probably 5-6db and function as a room heater. de KA4JVY Mark --- crawfish [EMAIL PROTECTED] wrote: I need a schematic of an amp using a single 450TL.
