CONGRATS – Bob, KK6KMU – On 24/7 Endorsement

CONGRATULATIONS, Bob on your successful, dedicated pursuit of this very difficult Endorsement.

 I believe you will be only the 31st of 2,872 members to achieve this one. You have already thanked the great co-members who gave up their sleep to help you put this one away. Now, go take a nap!

You have also made great progress on your 365/366 Award. Just 11 dates needed for that one. Unfortunately, to complete the 366 Award, you will need to wait until the next Leap Day, February 29, 2024.

Congrats again!!

Thank you for everyone's help.  Couldn't have completed my 24/7 endorsement without the help from Rick N7WE, and Alan KA5VZG.  Also thanks to Barry VA7GEM and Darin KO4EJD getting up and being there.

Thanks for the NM and AZ contact. I put in my logbook twice once for NM and once for AZ.

The best explanation of propagation I've ever heard was from Chief Dan George as Old Lodge Skins in Little Big Man:

Just my two cents.  Propagation has something to do with this also.  Yesterday I saw the other end of Dicks QSOs.  Could not even make out his trace but saw almost everyone he had a QSO with.  SSB on 20 meters allowed me QSO's all the way across the country but states nearly were silent.  I experienced this the last two days hunting Parks on the air.  I will never understand the mystery of propagation.

One more hour slot left to finished with my 24/7 endorsement.  Thanks again to Rick and Alan for being there.  Couldn't have got this far without you guys.  Schedule of the last  time slot below.

 

Friday, Oct 22 1100-1130 UTC

Thanks

Dick-
I second what Steve said!  You and Kathy really are doing a wonderful service for your fellow 070 members that are chasing grids.  You are PSK TRAVELERS extraordinaire!  You make every effort to give the grids to those that want.  Thank you so much.  Safe travels and enjoy the event!  We'll look for you in the audience and wave if we see you - hi hi!

Steve et all,

Your signal went up greatly when we moved the car basically 90 degrees, even though the hamstick should have been in a favorable direction to you.  Kathy and I did an experiment one time to determine if vehicle orientation made any difference to signal strength.  Since it was only anecdotally determine without the benefit of a calibrated range we found that vehicle orientation did not seem to make much difference.  Have found that being near tractor trailers seems to effect the swr, however. 

Still have not been able to figure out why the swr went to infinity yesterday.  Checked all connections and ran some tests and everything was fine.  Today swr never went over 3:1, usually down around 2:1.  Told the xyl that maybe the antenna over heated, hi hi.  She said at 80 mph with a 20 mph cross wind the antenna should have been air cooled.

Mobile & different antennas

 

Let me add one experience.
During this year's APE travels, I was using a Tarheel, Model 75.
When installing it on my car, at 1st I used a ball-mount that I had used in previous years, with a 102" whip, and a long random wire, alligator clipped to the small corona ball at its tip.
This year, I made an extra heavy luggage rack mount, that had the Tarheel motorized coil above the roof level. 
In testing, mounting the Tarheel coil above the roof level, on the luggage rack, was 2 s-units better on receive than the ball mount on the left rear quarter panel with the same antenna.
Then, replacing the 72" standard Tarheel whip with the 108" whip, added another 2-3 S units on receive.
My deduction is that raising the Tarheel motorized coil above the roof level both enhanced my receive and transmit.
If I get the time, I have a 17' telescoping stainless steel whip that I'm going to try. 
On the down side, there'll be no matriculating down the road with that beast attached. 
Milt.

That makes sense. I guess I shouldn't have been as specific about ground planes as I was, but your details are consistent with the thought: most antenna mounts on mobile vehicles will favor some directions and dis-favor others, due to the interactions between the antenna and the body of the vehicle, and the unique placement of the antenna.

Maybe we need to suggest that Kathy find a parking lot and drive in circles and let Dick stop her when there is maximum signal strength for each QSO. Only problem is that will delay their travels. (just kidding about the suggestion)

At the risk of speaking for Dick while he is in transit, here's a bit of info about his mount.  At least this is the way it was when we had lunch a couple of years ago.  The vehicle is a van and the antenna base (ham stick) is at about the midline of the van, on the driver's side rear.  I think he used a FireStik SS204 mount placed under the tail light assembly with the 3/8-S0239 nub about a half inch in the clear.  Given the 48" length of the lower half of the helical wound Ham Stick, about half of it is above the roofline.  Of course, the whip is well clear.  I think probably what impacts the pattern more than anything is the location of the antenna to the rear of the vehicle and the counterpoise from the van body being offset as opposed to centered.  That would explain the signal strength based on vehicle orientation.  My thoughts anyway.  I was too dumb to ever figure out a mobile mounting so just went with /P during my travels - magmount Ham Stick in the center of the vehicle roof.

Re: DM53

Stephen Melachrinos <melachri@...>
 

Sorry, didn't finish that.

My guess on the car orientation is that his antenna pattern is affected by how much of the car is between the whip antenna and the direction of the station--basically how much of a ground plane exists at that azimuth. So if (for example) the antenna is on the left rear bumper, there would be almost nothing going in my direction (ENE) from him if he was driving NW. But if the road were to turn and go NE a bit, that could add significantly to the ground plane and thus to the pattern in my way.

Dick is still in DM53--just managed a QSO.

One thing he just confirmed is that signal strength depends on orientation of the car.
