Re: [AMRadio] Modulator question.

Talk with Jim (WD5JKO), I think he has used a Crown P.A. amplifier as a cathode modulator, maybe an SB-200 as the final? Unless you're stuck with 13.8 VDC, I would look for something in the commercial P.A. type amps.(Guitar Center,Musician's Friend, pawn shops,etc.) I have a 45 year old Fender PA

Don't you just hate it when someone replies to your post with a different question and a dozen people try to answer his question but nobody answers yours? I'm sorry I can't help you out Dick, but I thought I would acknowledge your initial question. 73 K3PID - Ron H. _

Several members of the Gulf Coast Mullet Society Net on 3885 kcs use the combination of a DX-60 driving a Heath SB-200 and their audio sounds great, along with some RF punch to boot. 73 Robert W4RL Trustee of W4GCM - Original Message - From: "Bob Macklin" To: "Discussion of AM Radio

Re: [AMRadio] Modulator question.

A transmitter like the DX-60 puts out about 12W of carrier in AM mode. It uses Controlled Carrier modulation and does not require a modulation transformer. Bob Macklin K5MYJ Seattle, Wa. "Real Radios Glow In The Dark" - Original Message - From: "MUCHSTUFF" To: "Discussion of AM Radio i

Re: [AMRadio] Modulator question.

Have you considered using a car audio amplifier in a cathode modulation? If possible it could avoid finding another transformer that would stand the higher voltage and current in a plate arrangement. I give this some thought every time I'm in my friends car audio store. But, being one who always

Re: [AMRadio] Modulator question.

Hi Brian, Do you have a modulation scheme in mind? i.e., high-level, plate or controlled carrier or others While "rolling your own" can be done and certainly is rewarding when the whole magilla finally works...there might be other avenues to explore. For example, there are rigs

Speaking of AM Transmitters, does anyone have a source for plans to build an AM Transmitter for 75 meters in the 15-25 watt range?Thanks. - Brian/KF5CCN --- On Fri, 5/7/10, RICHARD GEORGE wrote: From: RICHARD GEORGE Subject: [AMRadio] Modulator question. To: "amlist" Date: Friday, May 7, 2010

[AMRadio] Modulator question.

I have over the years built several low power AM transmitters. I would like to build something a little bigger say in the 400-500 watt plate modulated. I have been kicking around the idea of using one of the solid state amplifiers made for car audio driving a reverse connected audio transformer.
