Re: USB Mice, SignalLink USB and Frozen Mouse in HRD.

Jerry N9AVY
 

Being in the alarm business, I've encountered RFI problems with smoke detectors from time to time. You know, you transmit and the smoke detectors in house go off.  A friend who is an RF Engineer finally told me what the problem was.  Seems that typical "el cheapo" household smoke detectors are ionization types (radioactive sticker) which have a high impedance front end which is prone to RFI.  The problem can be  solved by switching to a photoelectric type (light obscuration) detector which has a low impedance front end.  Most commercial smoke detectors are of the photoelectric type. 
 
My friend worked designing RF tight booths for testing radios and other RF devices where outside signal had to be kept out. Unfortunately, the smoke detector which was required by some fire authorities became a false alarm problem and that's how he discovered the solution.
 
RFI problems can be difficult to locate and fix.  We suffer from excessive, cheaply made electronics in most cases.

I've had similar problems, and the best I've been able to do is to weed them
out, 1 at a time.
The solution has been variable in nature. Sometimes just moving cable's
around, sometimes additional grounding, and hanging snap-on ferrite cores
all over the place.
There's no single panacea for eliminating rf in the shack. I'm using double
shielded, teflon coated, mil-spec rg-58 sized coax for all jumpers, except
for the output of my amplifier which is 1/2" Andrews hard-line to a wall
feed-thru panel.
I do have to admit that eliminating wires...with wireless has helped. My
mouse and keyboard are wireless and I've not had a problem with them.
One item that has me stumped? My Granddaughter gave me a small touch on &
touch off scent lamp for X-kah.  She was so happy that I was 'excited' by
the gift and of course she had the perfect place all picked out for it in my
shack. (Right on top of my Alpha 77SX amp.) Every time I x-mit, regardless
of the band or power, the lamp turns on, and then off with the next
transmission. I can live with that.
99% of all emissions emanating from my shack are at 35 watts or less.
It is interesting to see how other folks deal with these "opportunities".
A special thanks to K8SI, 070-1234, for interrupting his EU run on 17m this

Switch to LSB mice !
Well it depends on what band you're on. You remember, USB mice for bands above 10 MHz, and LSB mice for bands below 10 MHz. Of course, the standard convention is LSB mice for RTTY ops for all bands; if you try to use a USB mouse, you have to select the "inverted" mode on your software.

But this is a PSK club, and PSK operation is usually quoted with USB mice, even though the usual BPSK modulation is insensitive to inversion. (That's not the case with QPSK.)

A bit off topic for the group.....
OK I finally figured out (sort of) why my mouse will freeze when I xmit on
20meters, and react very slowly on other bands. Maybe this will help
others
who see this behavior. I have 3 main primary USB ports on my PC. 5 direct
on the Motherboard, one plug in card for 2 on the front panel USB access.
and one via two ports on the monitor which is plugged into one of the 5.

My Signalink USB is plugged into one of the other 5 on the MB. My
mouse is a
Logitech wireless, with a docking station for recharge. If the doc station
is plugged into any port next to the SL-usb, the mouse will freeze
when I am
in xmit mode, if I turn off the SL it will resume movement, even if I
am on
xmit. Very inconvenient as I like to jump ahead on my macro text and add
additional comments during QSO's

If the mouse doc station is plugged into either the front panel on the
PC or
the monitor (current location) I have no problems, though I am a bit
unsure
why it works OK in the monitor as that is plugged into a port next to the
SL.

I suspect this has something to do with how the PC internal system handles
USB assignments.

Re: USB Mice, SignalLink USB and Frozen Mouse in HRD.

I suspect this problem is more likely RF getting into the USB port via
either the Signal Link or the mouse docking station. Make sure you have
your PC well-connected to the same RF ground as your station. Also try some
ferrite beads on the SL and docking station cables.

Stray RF can do strange things to the state of USB and serial ports on a
PC/laptop, etc.

If the mouse doc station is plugged into either the front panel on the PC or
the monitor (current location) I have no problems, though I am a bit unsure
why it works OK in the monitor as that is plugged into a port next to the
SL.

I suspect this has something to do with how the PC internal system handles
USB assignments.

Re: What causes multiple signals on the waterfall?

Very good points Bob...
Some comments on your last statement.....if you see this affect on most of
the signals on the waterfall then
then yes I would suspect the sound card on the receiving end and start
there.
When you see lots of strong clean signals and then all of a sudden one shows
up
with mulitable traces, it's a pretty safe bet that the transmitter on the
other end
is having issues, however I would agree that it is not always the case.

With HRD, and my FT897, I can put an incoming signal on my center freq, and
using the the DSP DBF, I can block most strong signals (providing they are
not to
close ) on either side albeit at the expense of some signal loss on the
center freq.
I would be nice to notch out, but that will have to wait for another rig.

In many cases a signal that has multiple ghost signals on your
waterfall is caused within the receiving stations receiver, audio
card, computer.

This can be caused on both the transmitting and receiving end.
The only place you can truly measure signal quality is at the
transmitting end. There are a lot of variables between there and
the receiving stations computer screen.

Remember you are trying to receive a 100Hz signal using a 3000
to 3600 Hz Filter, the waterfall is handy but it has its drawbacks.

Learn to use notch filters or narrow filters. If your PSK software
does not support them ask for them to be added or use your
radios built in filters.

Power output, per se, has nothing to do with the signal quality
of your transmitted signal, be it PSK, CW, SSB etc. If you have a
clean signal you can run any of these up to the legal maximum
power output allowed.

In many cases a signal that has multiple ghost signals on your
waterfall is caused within the receiving stations receiver, audio
card, computer.

Overdriving. Exactly.
If you can't reach 'em with >50 watts, best to move one.
Zero indication on the ALC meter is the first step to preventing the ghosts.

I had another problem several years ago. My sound card died (mostly) and
I got many multiples of equal strength. Got a new card and all was well.

If I ever say "I've been a _______ for 40 years and I _______" that means
I have been a jerk who is unwilling to learn for a long, long time!

I appreciate polite input that helps me improve. Impolite input that
helps me is okay, too, except that it does not improve my mood.

The idea of sending someone a screenshot to help provide feedback -- great.

A signal can be strong and not have those images, and still be clean and
not
wipe out others on
the waterfall. Some other factors could be at work here as well. I have
seen
to much audio drive causing
harmonics and ALC not adjusted correctly can also cause this. Politely
pointing it out via an RSQ report
sometimes helps, but I have got the standard...." I been a ham for
40yrs...
and I know what I am doing."
Well at least we tried.... hi hi...... I am a firm believer that digital
modes should standardize to RSQ...

Back in the "OLD DAYS" hams would comment on "your overdriving your
audio"
etc. and be thanked
for trying to help. I want to believe that through proper signal reports
we
can get still have that respect
and the watching out for each other, and helping all of us.

This audio pairs have happened to me as well, from screen shots of other
folks who have sent me my image.
Once I made proper adjustments on my end, I was clean and no unwanted side
pairs.
Watch the audio, watch the ALC and above all have fun....

The theory I think is correct is that strong audio signals can cause
artifacts to be created in the soundcard. I see the effect sometimes with
strong signals.
