In short....
No Yes YMMV ....Dave "Paul Clay" wrote in message ... Do any of the solid state rigs from the mid-80s to present put out a good AM signal? If so, which ones? Is the conventional wisdom true that only by resurrecting a boatanchor tube transmitter can an operator get a nice sounding AM signal? Thanks! |

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. I have an Icom R-75 receiver that I plan on using. I like the idea of going with an old Heathkit because of their relatively small size, simplicity, and, yes, a bit of the nostalgia factor. But I've noticed that some of those units in good condition are going for almost $100 (more, if they've got a VFO, which I would have to have). I was surfing the net and saw a used Icom 735, which would interface very nicely with my R-75 (doesn't the 735 come with ICOM's CI-V equipment link?), for $250; yes, that's more money, but then I get FM capability, a built-in backup receiver, etc. As far as Heathkits go, the DX-60 was a relatively simple am-cw transmitter. About 60 watts, screen modulated. The Johnson Ranger, with 75 watts, was plate modulated, and had much richer audio, although much more complexity. It sounded as strong as other AM rigs running hundreds of watts. A Heathkit DX-100, if you can handle the weight and size, would be ideal; plenty of power, no amp needed, and a built-in vfo. I have an Icom 735 -- never tried it on AM. It does have the ci-v link on the back. Rated at about 25 watts on AM. Not sure whether many people will be able to hear you at that level, though -- most of the AM'ers I hear on 75m are using amplifiers to cut through the static and hash. Try 3885 khz at about 5 a.m., any morning. A lot of these guys have several AM rigs sitting around, gathering dust, and you could probably pick one up for a song. Good luck... Bob k5qwg |

Another example of a simple question where the threads stray so far off topic, he question isn't even addressed in the end. Paul, to answer your question: The FT101's sound very good with a D104 microphone. If you are looking for a good current solid state rig, the TS850 with the DSP100 and modulator feed is very hard to beat. Of course, these are my opinions only and others may disagree. Max |

Is the conventional wisdom true that only by resurrecting a boatanchor tube transmitter can an operator get a nice sounding AM signal? Thanks! 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 Exactly correct. I operate AM on a limited basis. I also run less than the legal limit for AM all the time. I do not operate on 20 meters, nor do I operate on 75 after dark in the AM mode. I can't speak for others.' Dan/W4NTI Dan, Like you, I run AM at times, but I do it during the day when many ops are at work anyway. Usually it's on 7290 or 95. If someone tells me I am messing them up, I will yield immediately. After all, it's only a hobby and courtesy should be the order of the day---at least, that's what I was taught. 73 Jerry K4KWH |

"Bob Stein" wrote in message ... snip Frankly, at the risk of incurring flames, I would like to see AM outlawed on the HF bands, just as spark was outlawed even before my time. On the other hand, I firmly believe that ham radio is a dying hobby, vis-a-vis computers, so it won't make any difference in the long run. \ Bob, W6NBI Let's put the shoe on the other foot. Even with the wider bandwidth with AM, why should the AMers have to yield to SSB? The point is to be courteous to ALL oper- ators and if there is a signal too close to me, I just move. There still is plenty of room. Why are ops so "territorial"--they MUST operate on a certain frequency or just DIE! They get all bent out of shape if someone happens to be on "their" frequency. Why not just move away a few khz? I will move in a heartbeat--even if a rude op tells me to "hit the road" (ever heard that phrase?). It doesn't mean that much to me. The AM guys usually operate at the top end of 80, 40, and 10 Meters, leaving the rest of the band to the SSB folks. The point is, all ops have just as much right to operate as any other. AM is still legal, and many fellas love it. I only do so on occasion and chat with a few of my friends on 7290. I run 40 watts with an IC706; most of the time, however, I am on SSB. I do still miss that warm glow in the shack and the sound of the CLACK as the dynamotor kicks on my old mobile Lettine about 38 years ago. Jerry K4KWH -- Remove spam-suppression X from my address |

Am surprised that none of the below posts mentioned the Icom 706 series! My IC706 (both of them) do excellent sounding AM and I have gotten quite a few compliments. 73 Jerry K4KWH |
