I used similar stuff when installing my submersable well pump. The gadgets I'm looking for are like the ones supplied with IC7000 tuner connectors. Just molded PVC or vinyl, should cost about $0.50 in small quantities. Several eBay sellers include them with the connector sets, so I know they are out there somewhere - but, again, since I don't need the connector, $8.00-$10.00 for the eBay set makes that unreasonable. OK, so I'm cheap! ;-) I'll stick with 'ugly' for the time being. They'll turn up eventually.

Thanks for your suggestions.

Thanks - interesting site. I'll have to bookmark it for future reference. However, the dust covers they show are for the wrong end of the connector. I'm looking for the boots that cover the wires as they exit the other end of the connector. Not crucial, but dress the connector assembly for neater appearance.

Forgot to tell you they will have the hoods in many colors!

Does anyone know of a source for the vinyl hood that fits over the 4-pin Molex plug for the automatic tuner connection?

Short burst of what? If it is RF feedback, then you DO have a problem
on digimode, even if it goes away after you start sending. You're just
over-riding it. You need to be able to have a clean signal at all
times.

Since the 7000 came with a Data port connector, I could replace the big
Acc conector with the smaller Data connector.

The SignaLink USB may help, depending on exactly what your problem is. It has isolation transformers that prevent ground loops currents from flowing between your computer port and the radio, power supply, etc. However it is always best to correct the fundamental grounding problems first.

I have *no* problems on digimode, just checked with a weSDR online. nice clean signal, only a short burst on the start and end of the BPSK31 transmission. So digimode seems to be okay. I also did some more testing with SSB, where the problem seems to be very bad with teh compressor on, and minor without. Will still pull the ACC plug when doing voice though.

I will get some ferite beads and do some more testing with the beads on the CAT/audio cable (TRX side, as near to the ACC port as possible).

As for the grounding, that will always be an issue here. I have to be lucky to get some decent RF ground in the shack. I do have the powerline grounding, but that is not acceptable AFAIK.

The SignaLink would not necessarily fix RFI being picked up on the cables connecting the audio device to the radio (either ACC or DATA). There again, the best approach is to determine the cause of excessive RF in the shack and correct it the best you can. Then adding some clamp-on ferrite chokes to both ends of the audio and control lines may be needed to attenuate the remaining RF on the audio. Many PSK31-type stations have considerable distortion on their signal due to RFI and ground loops and never know it -- just living with excessive errors on the RX end of the link. When you move to higher speed modes, then you HAVE to clean up the signal.

Using the data port will help whether you use your existing sound card (after correcting grounding and RFI issues) or go to the SignaLink USB (a good investment in the long run), since the audio input level is higer, relative to the induced RF on the cable. Plus you don't have mic audio getting mixed in.

If you have your digital audio going into the ACC connector, I would try unplugging it (and all other cables going to your computer, such as CI-V, etc.) when you get a bad report. The ACC audio input is very sensitive to RFI and ground loops. And RFI can be fairly sensitive to frequency, which may explain why it is intermittent.

And this is what caused the bad audio! Thanks!

The other problem with the 7K is that when you use the ACC audio input for digital, any noise in the room gets picked up by the mic and mixed with the digital audio, unless you remember to unplug the mic cable.

The DATA port is better for digital modes since it requires a higher drive level, but maybe that's what you're using already. When I use the ACC port, I put a 65K resistor in series with the audio input, connected inside the shell of the DIN-13 connector at the radio. That increase the audio level on the line to about 400 millivolts.

..snip

Steve is 100 percent correct when he talks about using the 13 pin ACC port for an interface. I had the same problem with my SignaLink USB and 13 pin cable. RF in the audio. Switched to the 6 pin cable and the issue was solved.

It has been a couple of years since I have used the Icom 7000 for digital. But I do recall that this, and can't remember which way got rid of the RF. Either leave the Signalink USB on, or off. One way will get rid of the RF.

Thanks, I guess it's simply normal then, just thought it was kind of strange. I've always had a bar or two of ALC when operating PSK and was trying to trace it to something, still dont know whats causing that, but I've been able to communinacate all over without ever recieving any complaints, so I'll take it everythings good.

You didn't mention what your mic gain setting was. I normally use about 30%, with the mic about 1-2" from my lips and off to the side a little. Compression will greatly increase any soft background noise in the room (making my big scope's fan sound like a "howling vacuum cleaner"), but you said that turning off compression didn't make much difference.

The ALC meter shouldn't be peaking at more than half of the green bars, although the noise you describe doesn't sound typical of overdriving things.

The next thing to try is adding common-mode chokes to the feed lines. Depending on what type of antenna and feed arrangement you have, you should add a common-mode choke (either a current balun or HF-rated ferrite chokes) at the antenna's feed point. If that isn't practical, then before the feed line enters the house and again on the output of the tuner.

Do you have a good single-point RF ground for the shack, with each part of the radio system (radio, tuner, computer, etc.) grounded directly to it with a relatively short, heavy (#6-8 AWG) wire?

Another common cause of RFI (especially intermittent) is loose feed line connectors. On PL-259's the point needs to be seated in the notch and the shell screwed down tight. Also, a poor solder joint on the braid (or broken braid where it was nicked when the outer jacket was stripped) to the connector shell will leak a lot of RF to cables near the radio back panel.

Your TBW settings could probably use some tweaking. I would suggest wide=200-2800, mid=300-2700. I don't use narrow, but having 500 for the low cut is too high, in my opinion, so perhaps 300 or 400-2600, depending on your voice. But that isn't causing your noise problem.

Without knowing more about your antennas, feed lines, grounding and their layout relative to the shack, its hard to be more specific.

Hi all,

I mostly do digimode on HF (and FM via repeaters on VHF/UHF), but on
occasion I do some phone on HF. It has happened to me a couple of times
that I get a comment on my audio (without asking), that it sounds "bad".
One user described it as "like a howling vacuumcleaner". Today I did
some test with a nearby HAM on 80m (an simultaneously via a repeater on
FM) and he didn't notice it being bad. Okay, speaking directly into the
mike revealed some plopping sounds and the digimode audio cable produces
some hiss from the computer (cheap USB sound dongle and direct couples
audio cables, no money for a Signalink USB or Microkeyer yet), but
nothing more.

At first I thought (and was suggested) that it could be RFI, but I also
got bad audio reports on 40W or less. And, moving the MFJ926B from 5
feet to 25 feet away from the IC700 didn't make a difference.

Then I suspected the Compressor and TBW settings. And okay, Wide
(100-2900) sounds better than Mid (300-2900) or Narrow (500-2900), but
neither sounded "bad". Even the compressor had just a minor influence on
the "badness" of the audio.

Until now I got a handfull of spontaneous bad audio reports, one from 15
miles away on 80m and the rest from DX stations (Lebanon, Egypt,
Switzerland, to name a couple). IIRC I used Wide/Compressor on all
QSO's, but switched off the Compressor on all occasions and that didn;t
help that much.

In digimode I get an occasional QRZ/AGN, but most QSO's are 100% copy
(unless the remote station is on the edge for me, but even them I get
mostly solid reports).

So, do any of you recognise this bad sounding audio phenomenon? If so,
any suggestions on how to avoid it? I'd like suggestion that don't
involve buying other microphones though. ;)
