I can't answer from experience, but the documentation says that the 320d is a 320 with an extra wide IF out port for a DRM decoder. How this was accomplished I don't know. It may have just been addin

Mainframe manufacturers often did this. IBM stopped around 1979 when they had an on line searchable database of bugs. It was employee only until around 1985 or so. They continued to publish the list

I'm in Israel and am looking for a TenTec rig. I'd prefer something in the range of a Corsair (or II) or a Paragon (or II), but I'm open to most offers. I can't afford an Omni, and I want the rig for

Are you kidding? While I'm sure the scout is a good rig in its own right that does not present the image that one would expect. IMHO more like a gold plated rotary spark garp and a Sterba curtain. :-

I don't have one, and in fact don't think I've even seen one, but I can relay to the group the information others have posted and I have read elsewhere. When the Paragon was produced it had the provi

Considering the amount of metal in the 10d head, that had to be one big transformer. Is it possible that the case ground was loose? I had a 10d fail with an open contact where the head plugged into t

Here is what I think you are saying: You want to connect the radio to an amplifier. Then connect the amplifier to a tuner. The tuner gets connected to different antennas based upon which band the rad

Hi, My Argonaut 509 dial cord needs to be replaced. I know that I could order one from Ten-Tec, but at this time it is impossible for me to do so. Has anyone replaced the dial cord on a 509 without u

Hi, I have an Argo 509 with a strange problem. Sometimes when I turn the rig on, or after I transmit, the receiver becomes very quiet. You can not hear atmospheric noise and signals that were in the

Hi, As part of getting my Argo 509 back on the air and running smoothly, I've decided to investigate two mods that I have seen before, but never saved. One was a "cleaner keying" mod, the other was c

Thank you, but Google is no ham's friend. They've invested over $100,000,000. in BPL. I've been boycotting Google since July. I have done a search using DOGPILE. It led to many sites that no longer e

I have one, I can test it out for you (D-104, Triton IV-D). Which model of the D-104 do you have? If it is an "amplifed" (really an impedance matcher) model, make sure it has a fresh battery and the

I had good luck with a TS-520se and an unamplified D-104 using an impedance converter from one of Doug DeMaw's (W1FB) books. It was a simple FET and a few other components. Mine was in a little box,

I forgot to ask, is it plugged into the rig directly, or via a 262g or similar power supply? Are you sure the mike is ok? One of the D-104s I bought used had the usual filter over the element replace

Thanks to everyone who responded with a suggestion. I think I fixed it by cleaning the "transceive/receive" antenna switch on the back. I say think, because when I did it this morning, 20m and 40m w

I've never seen one of those. The amplified D-104s that I have use an internal 9 volt battery. I assume that someone decided that they did not want to rely on a battery and added a power cable and sw

Are you refering to the hand mike or the stand mike? I've never even seen a hand version in person, But I have several of the stand version. They do get in the way but I've gotten into the habit of p

Yes, but what worries me is that almost all the time using the same antenna. my Argo 509, Triton-IV digital, Drake TR-5, Kenwood TS-430s and R5000 all read within one S unit of each other. The needle

I have a similar problem with mine. I found that the power supply may be marginal (it's a 120 volt supply on a 230-120 volt transformer). I also found that when I connected the antenna jack to a dumm
