Re: Topband: FW: The USA-CA Awards

[AB2E Darrell]

Jim,
You point out what is really an inconsistent CQ rule for USA-CA (not allowing 
LotW QSOs and requiring paper QSLs).
Of course this was the traditional way to submit when the program began and 
they had the little blue booklet you filled in the details, and you get your 
friends to view your cards and sign saying they've seen them.
Fast forward to now, CQ uses LotW to track and issue the WPX awards simply 
using the LotW confirmations and you apply directly for their award via the 
LotW site.

I mistakenly applied for the initial USA-CA award partially using LotW QSOs 
(but had 2 friends verify) and was summarily rejected by CQ.
No big deal, but at this point I doubt I will sort through thousands of old 
cards to pull out potentials for counties.

So I don't really see the reasoning, but maybe the logistics of doing so are 
more than I am seeing.

Perhaps I wrote poorly, Nick. Yes, the county information is there for
LOTW users who have entered their county. It is my understanding that
USA-CA does not accept LOTW confirmations. Am I wrong?

Topband: RFI tripping GFI breaker on 160m

[AB2E Darrell]

I trip a GFI breaker sometimes on 160m, usually in a contest 1500W.
Never had a problem when GFI outlets were the norm, but I had some electrical 
work done in an added
 room and the new code calls for a GFI breaker.
Has anyone had a similar experience and located an RFI resistant GFI breaker?

Re: Topband: Inverted L in contact with leaves

[AB2E Darrell]

Hi Pete,
No effect noticed here for leaves with L wire running over tree.
I just reinstalled my 160m Inverted - L on a taller tree (fed 10ft off ground, 
80ft vertical , about 52ft horizontal). It's been up all summer with leaves, it 
goes over the top of 95ft oak. My vertical wire is #12 THHN, insulated solid 
copper. I have 5 tuned radials of the same wire, but thinner gauge is also OK. 
I feed it with a 1:1 Balun Designs balun. I trimmed it slightly but it 
resonates about 1845 and gives me all the CW band. Tested with Acom 2000A at 
1500W outseems very stable as before mounted on a  shorter tree at about 
65ft.

Pete, even 1 tuned radial for your L, you should see it working and loading up 
OK if you want to test.

I used to easily find the tech supplement online from Butternut for tuned 
radials, but it looks like it's now gone.
Check this document out 
https://rudys.typepad.com/files/elevated-ground-systems-article-final-version.pdf
 . N6LF did some modelling and looks very similar to ON4UN's conclusions in his 
lowband book that 4 tuned radials achieve 60% of the efficiency of 100+ radials 
on the ground. Some may dispute this, but I've never had enough real estate to 
put down a full ground radial field of 100+, but I do have room to put up 4 
elevated radials. They can slope, go up and down but if you can, mount them 
about 10ft above ground.
The tuned radials are about 3.5% shorter than the 1/4wave element (see the 
formula). I cut them all the same as the element, and then gradually shorten 
them to adjust for resonance, depending on how the SWR looks.

In the past, the L has worked great for me. I now have about 115 countries 
confirmed on 160, all with an L.

73 and best of luck with the project,
Darrell AB2E

My inverted L is taking shape - about 60 vertical, the rest horizontal.
For a couple of months anyway, it is touching a number of leaves in the
vertical section.  I assume that's not a concern, but thought I'd ask
before I get a lot of radials down. First short radial is down and
MFJ-259 results look promising.  It's just a problem of waiting for lawn

Hi Everyone.

It's -10 deg F Wind Chill in NJ today (-23deg C) and that can mean only one
thing.
The CQ 160 CW Contest is here!

There are a few plaques that now need sponsorship. Please look at the list:
https://cq160.com/plaques.htm
If you wish to sponsor any of the open ones, or have another category in
mind please contact me directly.

Please visit our web site at CQ160.com and check the latest rules.
https://cq160.com/rules.htm

We expect all the rules to be obeyed as usual, and please spread out as
much as possible.
We realize there will be some FT8 activity around 1840.
I am hoping most of them will plug in their CW key and work stations the
old fashioned way.

Remember you must obey the ITU Region rules regarding operational
frequencies.
If you are found to operate outside these limits, it may be grounds for DQ.
Also, we will be doing a lot of RBN analysis to find power violations. We
realize this is not a true measurement, but we can find outliers. Please
observe the power limits set in the rules.

Also pay close attention to the remote RX rules, we will be alerted to any
use of remote SDR etc using web based systems.
*For Single Op Assisted only *You are allowed one and only one remote RX
within 100KM.

We expect good conditions, no storms and plenty of DX.
CU on Topband!

Re: Topband: 30 Ja's worked today on 160

Guy,
Good observations and I agree with you.
CWops is growing, and overall CW contest activity seems to be up.

I would bring up another reason for declining JA participation in general. 
Their  population as a nation is declining due to plummeting birth rates and by 
2050 will drop to 92 million from the current 127 million 
http://www.ipss.go.jp/pp-newest/e/ppfj02/ppfj02.pdf . There are likely other

"Nobody on CW" is probably answered better by few people listening and
most not having implemented an automated way to pick up on CW CQ's.
That's sort of built into the usual ham shack blend of FT8 and logging
programs.

In the contests, anyway, even RTTY tests and the recent RTTY roundup
with FT8 admitted to the fray, I see no diminution of participation,
the contests seem to be slowly growing.

The CWOPS weekly hour-long CW contests keep growing, with member ID
numbers well into the 2K range. It seems to have sharply caught on in
the last few years.

Re: Topband: Drone and pulley

[AB2E Darrell]

Hi Mike,
FB on the drone to string the line.  Best of luck with it.
In case the initial 3/16 line is too heavy for the drone, I have a suggestion 
that might help.
I too mostly use 3/16 line for tree antenna projects. I use an air cannon made 
by a local, which has a fishing reel, and I use Daiwa braided line initially 
over the tree (J-Braid 
https://smile.amazon.com/gp/product/B00ZYQXKU2/ref=oh_aui_detailpage_o01_s00?ie=UTF8=1
 ). Then I haul the 3/16 dacron rope over the tree with braided line. I've 
never had it break, and it's extremely light weight.

I would be interested in how you make out with the drone. The air cannon 
generally works well, but a few times the line has tangled on the way over the 
tree as the projective (6in pvc 1/4in) passes through the tiny branches.

This is the drone I ordered:

Prices on drones have really come down.

My plan is to tie 3/16" braided nylon cord to the drone; take off
vertically from the S side of the tree about 50' away to at least twice the
tree's height, move straight N at that height, and then descend straight
down *at least* 50' past the tree. (I'm being overcautious.)

That line will then be used to pull a 1/4" or 3/8" nylon rope over the tree
and make a loop (tie the ends together). At those ends is where the metal
pulley will be, attached at that point with about 2 or 3 feet of rope to
keep it from touching the tree. The 14 AWG THHN wire for the inverted-L
will go through that pulley.

*This drone may or may not work. *It doesn't have features like GPS that

And in a related story…..Laser Comm is teaming up with Auto Comm Ltd. of Palo 
Alto California to market to the Amateur radio Community the new Auto-Q radio 
package.

This new "radio station in a box" will utilize the best of Laser Comms new 
antenna system together with a completely stand alone Ham radio transmitter 
which will utilize the latest in a new digital technology called FT-8. The 
complete radio package is contained in a box less than 1 sq. foot and runs on 
the latest Elon Musk battery packs. These radios will make fully automated 
QSOs, and with a cell internet connection will upload all QSOs to the users 
DXCC and WAS. Head of computer development at Auto Comm. Jim Q Contact said 
“the new Auto QSO radio package can be deployed anywhere in the world. It can 
be set up at very rare DXCC countries, wanted counties or states and be left to 
run for months to make QSOs”. For those Hams that need a new country that has 
been difficult to get, they can deploy one of our units and then go home to 
their base QTH and work the Auto-Q Unit.”

Early testing has shown that the unit has been able to make over 2,000 QSO’s 
per month while left unattended. The Li-Ion batteries have a long life because 
of the very efficient radiation from the Laser Comm antenna. There has been 
some skepticism in the Ham community about the need for a ground radial system, 
but Auto Comm has done extensive field testing to proven that their antenna can 
radiate even better than a dipole at 300 feet.

When asked about the concern in the Ham community about un-attended QSOs being 
used for ARRL awards, Jim Contact said “our studies have shown that Hams these 
days are far too busy to spend the time at their radios to make QSOs. In todays 
society there are too many other demands on our time than to be stuck sitting 
at the radio using the old modes. Times have changed, and our studies have 
shown that today most Hams are more concerned about just getting the award 
counters rather than spending time trying to copy signals using the old 
outdated CW and SSB modes."

Auto-Q will have a table setup beside Laser Comm at Dayton this year so that 
customers don't need to walk too far through the mud.

them

and let them deal with that busy narrow road.

diameter coil as Tom Schiller used.
The Tornado design coils are now used on all their coil loaded antennas.
  I thought this might be interesting to you on designing the 80M coils.

Re: Topband: Where was everyone last night

[AB2E Darrell]

HI Dick,
I wondered the same thing.
I could hear a number of stations who were very loud but apparently had 
difficulty hearing me (I worked KV4FZ after a few calls...thanks Herb).
Thanks to those who worked me.
After 2 hours and only 25 stations in the log and numerous unanswered CQs I 
went to bed (0300-0500 op time).

Anyone get an error from the robot about the log date format?
I used N1MM and it seems in order. I emailed Tree.

 160 was almost as quiet as a graveyard last night.
 
 I heard and repeatedly called N7GP, NO3M and KV4FZ but received no answers.
 
 After an hour I went to bed.
