An inexpensive solid state rig for "AM" use
is the Yaesu FT-757GX or GX II. There are a number of them around for about $300.00 without the power supply (FD-700/757 heavy duty power supply). Any 13.5 VDC 20amp power supply will work with this rig and the power supplies, FD-700/757, are cheap as well. If you don't mind the size and weight there are a number of other trasmitters, ie Hallicrafter HT-32/A, HT-37, Heathkit DX-40, DX-60, DX-100 etc that will give you excellent "AM" results. The latter rigs would need an outboard receiver capable of "AM", not zero beating an "AM" signal although that can be done. The HT-32A is an excellent "AM" transmitter, I used one for years before selling it because of shipping weight and desk space. As for "Crowded bands", well that's been around for years and a few stations using "AM" won't be a problem. After all, "AM" was the original mode of voice long before "SSB" ever came around. That was not to mean that "SSB" is no more important that "AM", just to say "AM" still works and a lot of folks still use it. I have no problem with stations that want to operate "AM". So if you are looking for "AM" gear than charge on my friend, there's tons of it out there for the picking. 73's Mike DA1TNJ / WB8TNJ "Paul Clay" wrote in message ...

It may be fun, but it is also inconsiderate unless on a little used band. It takes up at least twice the spectrum of an SSB signal, and possibly more - hardly necessary given crowded band conditions. Not to mention the off-frequency heterodynes. Just two cents worth from an old timer (licensed for nearly 65 years) and brought up on AM. Bob, W6NBI I agree that it's important to be considerate, Bob. But even today, I think there's still room for playing around with AM, especially if one is carefull about the time of operation, the amount of power used (I'm planning on using 40 watts output or so) and radiating a good signal. No question that SSB uses less spectrum for voice communications, but, if one is willing to forgo the enjoyment (dare I say fun) of operating phone, one could conserve even more spectrum by operating CW exclusively. Obviously there's a trade-off involved (between the extra "utility", broadly defined, of higher fidelity signals and the extra, double as you say, bandwidth consumed), but, so long as operators exhibit good judgment and courtesy, I think the community's enjoyment of the hobby is maximized by giving people the choice of operating AM. - Paul, N6LQ |

Maybe so, but in my part of the country, there's a group that gets up at 5 o'clock in the morning to run AM on 75 meters, and their fat signals do little harm. Good to hear the old timers keeping alive some of our ham heritage. Bob k5qwg Just two cents worth from an old timer (licensed for nearly 65 years) and brought up on AM. Bob, W6NBI |

I thought the question was about what kind of rig is usable for AM. I do
not us AM but I do listen at times to some locals, and is good to see many modes still used. My Icom 765 should work for AM, and some day I might try it just to say HI to the group. There is plenty of room on the bands for their use. "Bob Miller" wrote in message ...
