Folks, I seem to have a new problem with my Paragon. It transmits spurs 600 Hz above and below the carrier about 10 to 20 dB down from the carrier. This was reported to me by someone using the spectr
This happens in Tune or CW. I can't generate a pure enough sinewave to measure in SSB, but will next week. I took some data on receive this morning and the spurs are down at least 40 dB on receive. I
Mike, Well, I went to measure, just to be sure, and everything was as expected - voltage wise. What surprised me was that the problem has now gone away. I would attribute it to contact resistance bei
Jerry, That not quite what Toby's talking about. The old noise blankers used a noise sample in a wideband receiver to perform a short (not extended by selective filters) duration receive mute, much l
Well folks, I've been biting my tounge (fingers?) for days but can't stand it any more! I must remark in support of Carter's comment. In terms of the folks who run the ARRL, I can say that they are d
Perhaps we first need a list to discuss the merits of having a separate list for CW? 73, Joel, W1ZR May I please suggest a separate list be established to discuss CW matters? I don't mean to denigrat
Well, I have owned a number of Ten Tec radios, used more and may own even more, depending on what I read here, so I like the choice. If they get divided up I would sign up for most, and then someone
John, I think I remember that the split audio is only available out the front headphone jack? If so, it would probably take a small stereo amp and then you'd be in biz. GL & 73, Joel Joel R. Hallas,
Interesting question. I've wondered about this for a while and had an opportunity to try my Centaur amplifier with a FT-2000 (in place of my usual Paragon) in full QSK mode this weekend. What I did w
Crit, It depends on the level. As I remember from my Corsair days, the attenuator is between the antenna and RF amplifier. If the RF amplifier input is being overdriven, it will still be if the gain
As with the postage stamps, Ten Tec will probably issue all future with the printing that you have and offer to replace your "defective" microphone element <g>! Together with my excellent O2 I purcha
The classic SSB-AM signal was that generated in the Collins KWS-1 of 1956. I agree, it's not exactly a transceiver, but another example of that kind of signal. If received in a receiver with 3 kHz fi
Actually I meant "classic equipment." I'm not sure I ever heard a KWS-1 in "AM" mode. The classic SSB-AM signal was that generated in the Collins KWS-1 of 1956. You mean a "classically inferior" AM s
Ken, I guess it depends on what you assume about the way the signal power is generated. You assume that the sideband power will be twice as high as the power in each sideband of a DSB-AM signal. I as
Hey, they're nothing compared to the "band modules" for my HRO-60! I might need to add a room on to the house for those puppies! <g> In fact for mobile operation the modules are a lot smaller than th
Al, While a solid variable signal generator is a great asset, I have a URM-25, but it isn't exactly trouble free or "small footprint", I also have an Elecraft XG-1 "S-meter calibrator. It puts out an
Am I missing something here? If a DSB AM signal is tuned with the carrier centered in a 6 kHz BW, I would expect to see just 3 kHz of audio BW. If you tune the carrier to one edge, you will be able t
Well, this is all very good info and suggests that the Orion sub-receiver is not really all that useful as a GC SW or BC receiver, if you really want to listen. I've made the case to a few folk in th
Dave, It certainly sounds like RF getting into the radio! Sometimes good grounding helps, but it is often even more important to find out how the RF is getting there and stop it from doing so. The po
The reason I got rid of my Corsair (perhaps was that I found the RIT range insufficient for serious DX "split" operation. I spent a lot of time unsuccessfully looking for the extra VFO and finally tr
