Re: Station weirdness

Rick and John,
Thanks for the ideas.  I am running the zepp with coax to the 1:49 I built, although I am going to change to a Palomar UNUN because the one I built is not standing up to the humidity in Houston.  The common line current makes sense to me, since I have a very good ground system, and that would explain why I don't see the other effects of common mode RFI.  One question I have is should I place the choke on the antenna side of the lightning arrestors ( all my coax runs go to a set of lightning arrestors tied to my ground rod, and then each one runs into the house and to my antenna switches), or should I put the choke on the radio side of the lightning arrestor?

Ron,

Usually when a zepp won't tune on one band the problem is that your ladder line is at a bad length.  Try adding or removing a few feet of the ladder line and see if that fixes it.

Not getting many contacts today.   I'm seeing activity on 20 meters.this afternoon but not getting anyone to hear me.  Made a few contacts on 40 this morning.  Sunny and mild today, a beautiful day to be out camping.  Solar panel not quite keeping up with demands so supplementing with generator daily.  Dinner in solar oven. 

Call me.....My APE needs more contacts.  I do have my minimum but need more.

Can't climb tower - doctor's orders.

About every year or so I disassemble tower mounted remove coax switch (it's down low) and burnish the open frame relay contacts. Ameritron 5-position. Only problem I ever had with switch was when a spring broke on armature and I repaired it ... something I used to do many years ago on the job.

Jerry,

I had a similar problem but limited to my vertical.  High SWR but an hour later tuned perfectly.  Two or three days later high SWR again.  Turned out to be a dirty connector at the antenna.  One shot of Deoxit and still working fine six months later.  Like Rick said 95% of the time it's a connector so might want to check them all out.

Re: Station weirdness

Rick and Jerry,
" Good luck and hope you find your problem and fix it easily."
Any insight on how to make those two go together would be greatly appreciated :-)  I seem to do well on the first, but miserably on the second!!  Glad to see that I am not the only one who has the weird and strange happen to them, although most of mine as a newby, seem to be self-inflicted right now :-).  Latest learnings:
1.  When you tune a 10M dipole on 80M it is really hard to get much signal out :-)
2.  An MFJ-939I is an amazing autotuner that I am pretty sure could tune my truck's satellite stub to 80M!
3.  Label your antenna switches!

The mystery right now is that I seem to have problem with my 132' end fed zepp on 40M, I can tune it flat, and the match shows good, but when I get above about 35 watts out, it starts tripping the self-protection on the IC-7100 and reducing power, but not to a regular level like it would if it were a steady high SWR, it kinda jumps, lowers power SWR goes down, radio kicks power-up, and the cycle begins again.  It tunes fine and I can get 100 watts to the tuner in on every other band, so I suspect I am getting some weird resonance bridge as I increase power, but it is definitely power dependant, since at about 35 watts it goes away completely.
My first kick at the cat is I plan to extend the end fed to 202.5 feet, which I think I can do in the space I have.  The other monkey in the wrench is that is is only about 10 feet high because the Neighbourhood Nazi's would crucify me if they knew I was operating an HF station here.  I already tried changing the length of the counterpoise, with no discernable effect.

I had something similar happen last week.  Sudden hi SWR on all bands.  Grabbed the MFJ 259B and started working backwards from the vertical.  That was about 9 AM and the heat index was already near 100.  The antenna checked OK.  Jumper to the bulkhead fitting checked OK.  Fitting itself checked OK.  But when I got to the main coax on the other side of the bulkhead fitting, the waterproofing was split and the PL259 wasn't even finger tight.  Now the waterproofing was 2 layers of self-bonding silicone tape covered with a double wrap of 3M Scotch33.  It had simply split - from the heat, humidity, and UV I guess.  First time I've seen that in many years of using that waterproofing technique.  And that wrap as new about 20 months ago.  After it split, I guess the PL259 just worked loose from expansion/contraction in our lovely summer.  Tightened it back, rewrapped with 2 layers of silicone tape, 2 layers of 3M Scotch33, and everything is back in normal range.  Took about 2 hours with several water and "go inside and cool down" breaks.  Someone once told me that 95% of all electronic faults are in connections!  In my instance they were right.  Good luck and hope you find your problem and fix it easily.

Rick:

Turned everything off for a couple hours and then all was okay again. Probably need to check coax connectors as you suggested. All affected antennas are on tower and fed into a remote switch on tower. Everything goes outside on single hunk of coax.

Not able to climb tower so can't check things up there. Have always suspected the balun on Force 12 C3 being a ceramic may have a moisture absorbing crack somewhere. Tower climbers now are too expensive ... all my usual guys retired from climbing.

Have noticed that when noise level in early morning in NIL that's when I may have problems.

I'll keep watching things and hope they go away, but that's wishful thinking.

Station weirdness

Jerry N9AVY
 

This morning I turned on rig (FT-1000MP) and hit the antenna turner button to make sure antenna was working. It shut down antenna tuner and said "high SWR" . Tried other antennas and had same results. Turned off rig for a couple hours and everything was okay and worked fine. Can't help but wonder if this might be moisture related or some external to antennas.

It's a puzzlement ...

PSK-31 is my favorite digital mode, but maybe not for a reason you have heard of before.

PSK-31 is my favorite digital mode, is because I am really lazy after a day's work, and PSK-31 is completely OK with that. 

Let me explain.  I work during the day, and like to stream a news program, or maybe a Netflix-type show in the evening.  What I do, is watch a show, with the bottom 2 inches of my computer screen devoted to the Ham Radio Deluxe waterfall set on a PSK-31 frequency, on either 20 or 40 meters.  If a stronger signal pops up on the waterfall, I pause the show, and if it's a CQ, I reply, and usually have a nice ragchew.  Afterwards, I go back to my show.  Sometimes, it's an Olivia contact, but PSK-31, 90% of the time.  I can usually snag a couple QSOs over 90 minutes or so.  Any of you who have worked me, that's how it happened.

There are other reasons, of course.  PSK-31 is thrifty on bandwidth, faster than Olivia, and it's a good "rag chewing" mode, things I appreciate as an old CW op.  But, the fact that I can make some QSOs while being completely lazy after work, appeals to me the most (certainly in the summer, but especially during long ND winters, lol).
