Re: [Elecraft] COM port problems

[Peter Dougherty (W2IRT)]

Reassigning port numbers did not solve the problem, and I did try that as one 
of the first steps in troubleshooting.

With one day’s work under my belt here’s where the situation lies as of tonight.

 

1.  After a cold reboot, the first attempt to launch either CI-V Commander 
(DX Labs rig interface) or N1MM Logger + may or may not capture the COM5 port 
used for CAT control (which was briefly changed to COM8 then changed back after 
finding no change).
2.  Launching either the old version of N1MM Rotor (v12.11) or the current 
.NET version, there’s about a very slim chance that it will work, but the usual 
result is that on attempting to start the rotor software it indicates both 
rotor com ports (COM1 and COM3) are already in use, and any attempt to invoke a 
direction command generates an error message (8018, IIRC) stating the function 
can only work if a port is open.
3.  Using the DX Lab “DX View” software, which interfaces with the rotor 
control software, if I repeatedly enable/disable the rotor control tick box, it 
**MAY** come back, and will keep working until the program is closed.
4.  If CAT control is in fact established, whether through N1MM or 
Commander, it will remain active until the program is closed. Once closed, 
either reopening it or opening the other control software will result in either 
program not being able to see the radio (i.e. the port remains locked out). 
Note than if it is Commander that is closed and N1MM does not see the radio at 
first, if I hit the “Reset Radio” bar in the bandmap several times it does seem 
to come back and start working again.
5.  Every other function of the PC is working the same as it always has, 
and once a COM port feature is working it remains working flawlessly.
6.  Troubleshooting has involved using Process Explorer to see if any 
devices are holding a port open when the problem is occurring, and none appear 
to be doing so. Phantom COM ports were removed, all USB devices were set to fix 
the issue of stopping the device for power saving (I hoped that one would work, 
but it didn’t), and all USB Serial drivers were deleted and allowed to 
reinstall themselves upon reboot. The results were identical.

 

In short, it appears to me that there is SOMETHING within Windows 11 that has 
changed somehow, and is locking serial ports on its own, with no easy way to 
release them.

Subject: [Elecraft] COM port problems 



OK, got a massive problem that just cropped up this evening that is far
beyond my understanding that has completely killed my ability to use my K3
with my computer.



After restarting the PC, suddenly I cannot communicate with the radio using
DX Lab Suite or N1MM+ on the assigned COM port. I have downloaded the K3
Utility software and it is able to connect to the radio on COM5, its usual
port, and invoke macros via the Utility. So I know there's proper
communication between the radio and the PC. But once I close down the K3
Utility program I get the first major problem. The radio goes into transmit
for 10 seconds, releases for about 4 or 5 second, and goes back in to
transmit. Only powering the radio off and back on again stops this behavior.

The main issue is that no CAT control software seems to be able to connect
to the radio at all. The radio is on COM5, and has been for at least the
last 4 or 5 years, and until today it has just worked, even after building a
new computer last November. I just rebooted today and everything went to
heck.

The kicker is that's it's not a K3 hardware problem, and since it works with
neither N1MM nor DX Lab software any more it's apparently not those programs
either, and quite frankly I just don't know where to look next. Compounding
the issue, and likely related to it, the N1MM Rotor control cannot find
either COM port assigned to the rotors (COM1 and COM3). I have tried
removing the ports and re-adding them in Device Manager but the problem
still persists. I am absolutely prepared to pay a certified systems
professional to diagnose and fix this, but with ultra-specialized radio gear
I doubt they'd be able to figure it out either. 

Re: [Elecraft] Using the Antenna Tuner in the XPA100

[Fred Jensen]

One would think so, but maybe strangely, there is no sign of any RF on 
the coax at the rig connection.  My coax run is 100' of RG-8 laying on 
the ground.  Because of a walkway made of pavers between the house and 
autotransformer on the fence, it runs under the antenna along the fence 
to a conduit under the walkway, and then back next to the foundation, 
still on the ground, to a 1 1/2" entrance weather head and pipe into the 
house just above the floor level, and then about 6 ft to the rig.  The 
autotransformer on the fence has a ground screw with a wing nut but 
nothing is connected to it.


For awhile, I just had a 25 ft coax run laying across the walkway and it 
all behaved the same.  Wife "convinced" me to get the black hose off the 
pavers. [:=)  I expected I'd have to choke the coax at the house 
entrance [and maybe a lot more], I have no idea why I didn't need to.


Full Disclosure:  While I've spent a number of years in college, have a 
couple of degrees, and am comfortable with the mathematics of RF, I'm in 
my 70th year with a license and my usual approach to anything is the old 
school, "try it first."

While this does work for transmitting, it also is a recipe for "RF in 
the shack." In addition to "lighting up" the shack, the counterpoise 
does not stop at the station -- it continues on every wire connected 
to the station, including power wiring. At a minimum, this demands 
serious bonding of everything in the station.

Re: [Elecraft] Using the Antenna Tuner in the XPA100

[Fred Jensen]

Mike,

I'll assume you're going to end feed the wire.  The impedance at the end 
of 130 ft will vary all over the place on different bands.  My WOOF 
antenna is 136 ft end-fed through a 9:1 autotransformer ["balun" may be 
the most misunderstood, misused word in Amateur Radio]  The outer 
surface of the coax shield to the rig forms the counterpoise [i.e. the 
"other side of the antenna"]. The ATU in my K3/100 gets a good match on 
all bands up to 6, although I've never gotten an answer from anyone on 6.


That said, our hobby name begins with the word "Amateur."  You can go 
old school and just try it ...

I have never used an autotuner before.  Thanks for your input.

your voice. The article says “KX3”, but the procedure is the same for the K3. 
Most of the advice came from K3 operators. The idea to use the DVR is from Lyle 
Johnson, KK7P.

[Elecraft] The RIGHT way is to adjust COMP

[Bob McGraw]

Start with COMP at 0, adjust the MIC gain while speaking normal voice to 
attain 5 to 6 bars {no more} as indicated on the ALC meter.  Then adjust 
the COMP for a value to indicate about 10 on voice peaks.


For those that believe in using the "I turned it up a little bit, now 
how does that sound?" approach, . forget it.  Set it correctly as 
described above  and it will sound great.   There is a right way to do 
this.   Anything else is flying by the seat of your pants.


If you desire to have it sound different, then twiddle the EQ values 
until your hearts content.   After doing so, you may need to reset the 
MIC and COMP levels to be correct.


I much prefer to listen to my signal on a remote SDR and record my 
signal on the SDR site. Then listen to it in my shack on my speakers.  
Then I know HOW MY SIGNAL SOUNDS.   That's what is important.   I make 
adjustments from there.


As to others, they can adjust their receivers, their speakers, their 
hearing aids and a host of other things that will make ones signal 
sound..err, many different ways.  So which one of the "many 
different ways" is best?  Likely none of them.

The RIGHT way is to adjust COMP for a METER reading of 10 dB on voice
peaks.

Re: [Elecraft] KX2 on Commercial Airplane

[Thorsten Fricke]

Hi all,

Am 26.06.22 um 23:38 schrieb Michael Parsons:

I fly constantly and have been taking my KX2 with me every single time for the 
last year. I also currently carry an IC-705 with its battery and two additional 
Bioenno 4.5ah batteries all as carryons. I fly around 50 times a year and never 
have been stopped or searched other than the general X-ray machine as per usual 
flying TSA requirements. It’s just fine to take that with you as a carry on.


I can fully agree and confirm this! My daughter studies in Tel Aviv and
everytime I am going to visit here, I take my KX2 with me. Even with El
Al there is no issue at all to take it on board as carry on.

The ONLY issue I have... my backpack used as carry-on contains the KX2,
a X230 Laptop, a Kindle and my D300 (incl. 16-85mm lens)... this needs
to be unpacked before and packed again after the x-ray machine... and it
is quite heavy ;-)

[Elecraft] Using the Antenna Tuner in the XPA100

[Mister Mike]

Hello Elecraft Listies…..

I want to know the best way to use the built-in antenna tuner with a 
random-length lomg wire (130’).  Inasmuch as the RF output of the tuner is a 
PL-259 for coaxial cable I would imagine I would use a balun (4:1?) or unun 
with the shield side to ground and the hot side to the wire.

I have never used an autotuner before.  Thanks for your input.

73,

Michael, W1RC
