Jerry-
I see people working him but nothing of his trace.  So I can't help you triangulate him.  Kind of tough to do anyway...with only a vertical.  Hi hi!

Joe - I have looked at this one, but the thing that turned me off of it was that it requires a Tee into your TX line. How that little device is supposed to hold up to 30-50 watts is beyond me, but I don't want to cut my signal anyway. I believe a Tee is a -3db device, but I can't swear to that, but I can theorize that it'll introduce an impedance bump and possibly treat one section of coax as a terminated stub, screwing up the characteristic impedance of the antenna system.

Anyhow, if you make sure your compressor and EQ are off, and monitor your ALC meter like a hawk to ensure that you always have ZERO ALC (by varying your audio drive level), you should be good to go.  I've gotten IMD reports (on dead PSK31 carrier only - the RIGHT way!) in the mid to upper 20's by setting my system this way.

I'm not saying the IMD meters are bad devices by any stretch, especially that one that "sniffs" the air. If this one could be made to do the same by just attaching a separate antenna to it, it might be neat as well. It's the direct connection that worries me.  That said, he's been building these things since 2003 or so it looks like, so......

Hi Joe-

I've never tried one of those.  I went with the IMD meter way back when I started PSK 10+ years ago.  Mine is still functioning daily!  The things I didn't like about the PSKMeter was it had to tap the coax (not stand alone), having to run on the computer, and the automated control.  Back then I was using PSK Deluxe (which later morphed into DM780) with HRD (Simon's free version) and didn't want to fuss with trying to get all three programs playing nice with each other.  Some of my friends reported difficulty with the rig power/pc sound card drive way of control. Sometimes reducing rig power without reducing sound card drive allowing ALC to kick in which distorts the signal. I don't use the pc sound card anyway (always microHAM interfaces) so I just went with Clint's design and have never considered changing.  You might check out the eHam reviews for the two products.  They are in Reviews-Categories-Specialized Amateur Communications Products. Hopefully you'll get some comments here from members who have actually used the PSKMeter.  It seems to be the only option currently in production!

Maybe someone who knows Raspberry PI or Arduino will come up with a stand alone equivalent of the IMD Meter.  That would be neat!

There is a kk7uq IMD Meter posted for sale on eHam.net this morning.  Don't know anything about the poster or that particular unit.  I have used the IMD Meter for years and personally think it is something every PSKer should have.  BUT.....these are no longer in production due to part obsolescence. . 

Back in January of 2016, the club got a opportunity to order one from Jim KJ3N who was doing the final build-out of units from the his inventory of no longer available parts. As I recall, the price was substantially more than this guy is asking.  Several members ordered and finished out his production forever.

40m tonight

 

40 meters is in great shape this evening! The band is stretching out a bit from here in Southern 6 land.

There's some very nice cw signals that go with the ARRL Int'l DX 'Test, CW weekend, and a few nice wide, strong and clean bpsk31 signals. Some Spanish language broadcast station is also making an appearance.

It's been a while since I've heard one of those.

Hi Jerry,
 
I’ve seen this often with very strong signals input to a soundcard.  
 
I think the soundcard creates sidebar artifacts around the central strong trace that contain the same information as the primary signal.  The decode software algorithm will decode the sidebars just fine.
 
When the signals are at normal levels, I don’t see the sidebars.
 
Just my guess …

Last night and today I saw a single signal on 40m and it was strange looking.  No setting on rig have changed as far as I know.
 
What I saw was three signals with the center one being the primary and on either side (about 10-15 hz) were sidebands with same station. It was a zero in MN who was working a KC7 .   Both stations seems to have same problems.   Am thinking it may be my FT-1000 MP  or weird propagation.

Hi Jerry,

 

I’ve seen this often with very strong signals input to a soundcard.  

 

I think the soundcard creates sidebar artifacts around the central strong trace that contain the same information as the primary signal.  The decode software algorithm will decode the sidebars just fine.

 

When the signals are at normal levels, I don’t see the sidebars.

 

Just my guess …

Last night and today I saw a single signal on 40m and it was strange looking.  No setting on rig have changed as far as I know.

 

What I saw was three signals with the center one being the primary and on either side (about 10-15 hz) were sidebands with same station. It was a zero in MN who was working a KC7 .   Both stations seems to have same problems.   Am thinking it may be my FT-1000 MP  or weird propagation.

 

Any have an explanation ???

And sometimes applications use the sound card and leave it in various random states. 

I have two sound cards - one for the digimodes and one for system sounds and other applications.

Jerry, sometimes Windows updates reset the sound card settings . . .

Yes, but my West Mountain Radio M-8 has not changed settings since at least 2006.   It was fine until recently where I noticed  the sound card sliders were almost double the original settings.  Don't know what changed, but it might have been something in soundcard components. 

 

Otherwise, it's been flawless all this time through over 10.300+   contacts. 

 

Don't want to get into which interface is better than others.  Just know I have confidence in my station (most days).  Also have a Signalink on the shelf.

That's why I like the Signalink, it's got knobs to twiddle.

Paul :

 

Thanks for that bit of info because it cleared up things here.  

 

Somehow the soundcard sliders were set to almost double  normal level even though I haven't touched them in years. May have had something to do with age  or one of the upgrades the computer wants to do.

 

My crummy looking waterfall now looks less polluted !

 

Thanks again.

Guys,

I have had similar issues in the past. It was definitely my sound card. After lots of experimentation, l learned that a good decode required a setting of at least 52% AND that distortion began at 55%. I have mine set at 54% now and I check it periodically. Invariably, whenever I have problems, the setting has been nudged. Resetting to 54% is my solution

 

YMMV

It's not your radio !!   Seems to be at my end and saw same problem on 20m this morning.  Dan, KZ3T, reported same thing.  Looks to be something caused by propagation conditions or might be soundcard problems on my end; they looked a bit high so back off on sound card sliders a bit.

 

Don't worry , not your problem.     If it were  I would tell you to disassemble radio down to component level, put it all in a bag, twirl it around your head and squawk like a chicken  !    Hi !  Hi !

I will try to be on again this evening.  If anyone sees my signal looking like this please let me know so I can track down the problem.

Not sure it is your radio Jerry as I saw the same thing, center signal (main) with two side signals. When I went to them it was the same station.

Thanks Mike !

 

Just looked at  K5SP  on 49m a few  minutes ago.   About 6-8 Hz. either side of his main signal I can see 2 "sidebands"  which have same data as main signal.  Might be my sound card flaking out ...  could be time to finally switch over to Tigertronics USB.

 

Appreciate the info.
