Re: Proper adjustment of audio levels for transmit

 

There's a few ways to feel comfortable about your signal. I use a PSK Meter, & a Bird peak reading wattmeter. I adjust the output of my digital radio, a Kenwood TS-480HX, to 30 watts as measured on the Bird wattmeter. Then I adjust the output control on my RigExpert Standard to a full sine wave display on the PSK Meter display. When transmitting text the PSK Meter tells me visually and with text when my signal is "OK", "UNDERDRIVING" or "OVERDRIVING". I make adjustments to the signal with the RigExpert Standard.
Seems like a lot of adjustments, but once set, it rarely changes.
And, I'm of the philosophy that you want no ALC showing on the radio's meter.

Okay, good to hear, thats the way I have been operating. Did decrease the RF out to 50 watts and adjusted the interface to read about 19 watts on the Wattmeter, made a couple contacts that way today.
But WOW! there were some strong signals on 20 today!

Re: Proper adjustment of audio levels for transmit

Not all bad signals are distorted audio some times it can be ground loops, RFI in the audio lines or chassis and it also can be a very dirty sound card with high THD% or receiving interference from the computer itself into the sound card. I had a couple of cards that produced some horrible audio.
I notice on one of my rigs that the ALC does not read correctly at different power levels , One way I have learned to set up my audio is to turn my RF power to 100watts then adjust on the audio to produce maximum swing (using BPSK31)general with a dead carrier around say 60 to 70 watt range and swinging up to 100watts on peaks. Then I can back down my RF power knob to any pep power I want to have. I have had good compliments doing it this way and the swing is indicating that the radio is staying linear.


While this is all generally good advice, the only way to be sure all it well is to measure the IMD outside the signal chain as distortion can be introduced anywhere in the signal chain. It is a good idea for anyone who is really serious about keeping it clean to invest in a standalone IMD meter.

Jim,
 
Good post! My problem is I run a Jupiter and it has no meter, the ALC is a light, on SB its supposed to flicker, however on PSK I have not found much to tell where things shud be set.
 
When I was a newbie I was told, on the zair, to run my power out to maximum (100 Watts) and back the power down to 25-30 Watts using the soundcard. I have a few e-mails stating the light shud be 'on' another says it shud be 'off' and still one that says it shud 'flicker'.
 
I shud add I get good reports ie 599 all the time, only once I was told my signal was bad, and worked Africa QRP. (Power out 100 watts, Signalink adjusted so Wattmeter read 5 watts.)
 
So, if you see me on, and don't like the looks of my signsl, Please e-mail me.
I don't want to be "The skunk at the digital party", to steal a phrase. Tnx agn Jim.

Subject: [070] Proper adjustment of audio levels for transmit

I am increasingly running across stations that are over-driving their transmitters. When I can copy a signal at 3 points in the filter passband, that is a problem. And the distortion on an over-driven signal often makes the signal difficult to copy or un-copiable.

1) When transmitting using USB (Upper Sideband) and audio input via the mic jack, adjust the audio drive to a point just below the ALC kicking in. And remember your PSK-31 audio is going through the same speech processor settings as you mic audio, so turn off speech processing and/or compression.

2) If you have a DATA mode, i.e. the Elecraft K3, using the LINE IN connection, set the audio level (MIC) to 4 bars of ALC. Then adjust PWR to the appropriate power output level. LINE IN in most rigs by-passes any speech processing and/or compression.

3) Do not be offended if someone gives you a bad report, check your audio drive. An over-driven signal is bad for everyone, and indicates a lack of skill on the part of the operator.

Re: Tips on how to work DX from a DX station

Jim K5SP
 

Scotty, I think that list originated during my tour. The BritRep at the
time would not let us get a VQ9 call. I dont think he knew how, as it
was shortly after the Seychelles separated from Brit Empire. I was there
1976-77 as Tech Control Supervisor, then to Training PO for the
Commsta/Chief Op of the Mars Station. (our CO was island commander, and
we took it over from the CB's then and put me over there). First thing I
did was shut down the station, took down and cleaned/tightened loose
elements on the antlers, and aligned all the gear. That 90 foot
freestanding tower was erected on my watch there. Once we got that
thing up with all that height and those elements, we could hear stations
from all over. A friend of mine K6JMZ was a warrant ham that was there
at the same time I was. We had a ball, and had some no qsl lists also.

Wow Jim, Talk about bringing back memories. Former VQ9RS (Aug-Dec
1980) I had the same issues. I used to rag Chew with a ZS, A9 and A6
back in the day. It was amazing how many Rude ops would break the pile
when we just wanted to chat.

Did they have the BAD List still there? We used to keep a list of Dont
ever QSL at the 2 operating stations. We compared the log to that list
(Time consuming if you ran a pile) but before I sent the logs to my
manager Id check the list. I also Noted bad OPS in my log and Lyle
(N6BLN) my manager would send the card back with a note that stated
due to your poor operating practices you would not be getting a card
and that you had made the VQ9 Do not QSL list. Amazing the long
appolgy letters we got.

Anyway, I would always start my piles with a Rule list of what I
expected. If those rules were not followed I would leave. It was
amazing after a couple days of that how the Word got around the DX
nets of the 80s that when I was on you best follow the rules or I
would quit.

Hi Steve and the group,
 
5. Ignore me if I ask you to work split. That's really so everyone ELSE will get out of YOUR way.

I wished more DXpeditions would use split frequencies when working PSK31. I can say that there are always a few "tailgaters" who do not realize that they may be interfering with a call intended for someone else.  This happened to me a few times this year, once when the tailgaters were finished, all I saw on the waterfall was "KJ8O de XXXXXX pse KN".
 
And I am guilty of it too, but I think if we all work together, more people will get their chance to work the DX stations.
 
Ok, I'll step down from the soapbox....
 
Thanks for the great job you're doing, Steve.

Re: Lesson Learned

 

Steve,
Does that FT-2000 have enough buttons and knobs on the front panel for you? :-)
I like my FT-2000, and after a month or 2 of mastering what I was interested in, I now use it for CW only.
My digital radio is a Kenwood TS-480HX. I like the small foot print on my desk, and I can go to 200 watts for RTTY when necessary.
Have fun down there.

I learned today that Yaesu's Digital Noise Reduction (DNR) and PSK31 don't mix well together.

I had been wondering why many of the signals on 20m were distorted. I didn't have the problem on 15 or 10, but 20 was different. On some signals, I didn't get railroad tracks on the waterfall. Signals were strong enough (based on color and brightness) but it was an almost-solid blob.

On this trip I'm using a Yaesu FT-2000; the FT1000MP Mark-V that I used last time is broken. With a little bit of playing, I figured out much of the rig, but still had that problem on 20m.

So today I started paying close attention to everything in the display, and correlating the indicators to buttons/knobs on the front panel. And there are a lot of those, 16 knobs and 75 buttons! But when I pushed the DNR button, a "DNR" light on the display went out and the signals cleared up!

DNR is probably a great feature for audio signals, but wreaks havoc on PSK. My guess is that it is destroying the phase shifts. Your ear can't hear phase, so it can be used as a "degree of freedom" (in other words, something to be sacrificed) for audio signals. But for a signal where the information is carried by phase changes (like PSK), it's a disaster!

So, my apologies to anyone who tried to call me and I couldn't decode it. I know what to look for now.
