Title: Longest Mobile Contact?
Post by: KC5VUW on February 25, 2009, 09:07:15 AM
So I was just wondering.  What is longest mobile contact people have made?  My longest was about 4076 miles from Fayetteville, NC to Maldegem, Belgium this morning.  This was from my mobile to a fixed location.  I was running an Icom 706mkIIg with about 100 watts into a homebrew fullsized screwdriver.  How about you?

Longest mobile QSO for me??  Almost 2 hours.  

Enroute from Lake of the Ozarks, Missouri to my home QTH.

Furthest QSO worked Australia on 40M running 100W and a Yaesu ATAS (he had a quad beam).  Longest QSO was almost 3 hours on 40M CW between KC, MO and Des Moines on I-35 with a station in TX.  Most memorable, worked Poland on 12M with no one else on the band and on the drive back from Dayton one year snagged W1AW CW mobile on 20M, QRP.

Hummmm! Longest in terms of distance? Or time? Or longest in terms of boring subject matter?

I have worked Heard Island several times from various locations, all of which were about 12,000+ miles. This is about as far as you can talk from any two locations on the face of the earth.

I had one conversation in about 1975 which lasted for nearly 8 hours, including two stops for gas. But that doesn't hold a candle to two friends who traveled from Ohio to LA, and talked nearly the whole time.

Then just last week, I had a conversation which lasted about 40 to 50 seconds, that was about as boring as any I have ever had. When I hear "QSL-QSL-QSL", and "Roger That" three times each in that length of time, I just pulled into my driveway, even if I'm 100 miles from home!

I routinely work Hawaii mobile on 20 meters SSB and probably my best DX contact was busting a pileup to work a LY2 station using 100 watts and a Hustler MO-4.

Southern Australia near the Peak of the last sunspot cycle. I wasn't paying attention to the call at first I thought they were a Canadian station! I was running 20 watts into a Wilson 1000 magnet mount on my old Mitsubishi Montero (Before they became yuppie transporters) I was fishing on Island Beach St. Park on the Jersey Shore Late in the afternoon. monitoring for my best friend Scott, then KB2TXE (He took his dad's call- my elmer after he SK) 28.320, the rig was a "mono band" (pseudo CB) Emperor TS 5010, It's the beacon now at 28.138. Still Virgin too! Recently I worked a station on the Isle of Man from my Jeep Wrngler, 20 meters, Hamstick Yaesu FT757 GXII @ 90 watts.

Opps, For got to mention- The Longest running QSO I had was with Scotty, Again I was on Island Beach and he was at his home in Pt. Pleasant- We gabbed for 2 hours, In between me checking the bait and tossing back the occasional sea robins.

Ok.  So I forgot that "longest" could mean distance, or time.  Plenty of good stories out there.  I can't imagine talking on the radio all the way from Ohio to Louisiana!  I broke a bit of a pileup this morning and got into Lithuania.  Distance of almost 4700 miles.

One important fact to remember Tim, is the number or distance of any contact, DX or otherwise, has little to do with any antenna parameter, including efficiency. All a log book entry proves is the band was open between the two sites.

Quite a few hams in Hawaii operated parked mobile, usually close to saltwater, because of housing restrictions. Contacts that would be hard to believe anywhere else are pretty routine. It's about thousands of miles of saltwater in every direction.

When there are some sunspots, even just a few, winter long-path phone QSOs with the Middle East are doable with 100 watts and a mag-mounted  Hamstick at the beach. And they'll usually give you a 5/7 or a 5/9. That's 16,500 miles. How can that be possible? Well, there's an all-saltwater great circle path between here and southern Africa.

The surfing and the girls here are better than they are anywhere. Same goes for the DX.

I've worked 300+ DXCC and 5BWAZ in the last 9 years of mobile operation.  Longest probably were long-path QSOs from Arizona to ZS or northern EU, although it's hard to be sure since you don't really know the exact path taken.  My prides-and-joys are probably VK6 or LA (Norway), both on 75m...or maybe Arizona to ZD7 on 6m SSB!
When the band is open and you have a reasonable antenna installation, you can truly work the world!

My best two contacts mobile in the last 6 months were Israel on 20 meters and Australia on 40 meters from my location in NW Ohio. And I credit K0BG for his help in setting up my mobile station correctly.  His advice on his website and via my numerous email requests for help were right on.
I'm running a Yaesu FT-857D to a Tarheel 100A-HP using a SGC SG-500 amp powered with an Optima Red Top battery and a Rockford Fosgate 1 Farad Capacitor.
By the way, I worked Israel barefoot.

Over the years I've worked quite a few European stations from the mobile using 100W and a Hamstick. As Alan said, it has more to do with propagation than antenna efficiency.

Anchorage Mobile to Jamaica (4900 miles), Dominican Republic (4700 miles), Yugoslavia (5200 miles) or New Zealand (7088 miles)...guess the Kiwi's win that.

Ford Pickup, FT-857D, 100 watts USB, Hustler TriBand Coil Setup.  20 meters.  Just worked Jamaica in fact this week.  Booming into Anchorage all week.  One huge pile up to him from Asia and my itsy bitsy mobile made the trip.  I love this hobby!

In regards to kilometers per watt, my best record is from Mojave, CA (Hwy 58 / 14 junction NE of LA, CA) to Easter Island using a Yaesu FT-817 5W mobile with a mag mount helical wound 48" Firestick CB antenna (cut down for 10M). Of course band conditions will directly impact any distance records one is trying to achieve.

As to length of time, I have had mobile QSO's while traveling cross country that went well in excess of an hour on regular occasions.

AS for quantity of DX contacts while mobiling, I run a FT-100D 100W transceiver with a Don Johnson W6AAQ DK3 'Big Stick' full size screwdriver antenna. With this setup, I have logged every continent, nearly enough QSOs to qualify for DXCC and WAS mobile.

I also use that same setup for 6M when it is open. I like to travel around giving out rare grids when I am able to be in one.

I've been mobile here in Florida off and on for the last five years or so. I usually work 20m phone, occasionally 17m.

Usually I'll talk to anybody who is easy to hear in the mobile environment, but I can recall working Japan once, Australia a couple of times, and European and South American stations frequently. I never try to work split while driving. Once on the way home from work I heard a huge pileup (condx were pretty lousy and the DX few and far between) and it was S9SS popping through. I figured I didn't have a chance under the circumstances, but I got him first call, and he incredulously asked, "Did you say MOBILE?" You just never know!

All contacts were with a TS-50, 100w, Hamstick with mag mount on a Saturn VUE. Maybe the saltwater adds a few dB!

Could I do better with a better antenna? Possibly, but this simple setup keeps me busy enough.

I only installed my Icom IC-706MKiiG in my Nissan Navarra 4WD approx a month & a 1/2 ago.

My Longest Contact thus far is from Mobile in Blacktown A Western Suburb of Sydney to K7ZSD in SCAPPOOSE, OREGON. Distance of 12383.63 KM'S. I also contacted Station in Argentina but I don't have his Gridsquare so I cannot calculate the distance.

Just had my longest distance QSO's this morning on 40m. I worked ZL4IR at a distance of 18,651 km ( genuine 58 report received )and within the hour also VK7GK (16,849 KM) and ZL3OZ.
These QSO's were between 05.20 and 06.15 using 100w from an ic706 and Outbacker Outreach 500.
I was parked within 20m of the ocean and a clear take off in the direction of VK, ZL etc. Also worked JT1DA ( 20m )and OY9R before 07.20.
So great to work some long distance DX on 40m and good luck with your mobile operations whatever you use.

On the way to work one morning on 20m I worked the 3B9C dxpedition from VE1 land. That's about 15,000 miles as it was early morning long path at the time. Antenna was a 20m Hamstick with just 100 watts.

I think K6YNB/N6NB made some contacts over 443,000 miles from
his mobile station shown here:

Longest mobile  contact was mobile to mobile with the other amateur in Madeira Islands (off coast of Western Africa) from West Texas/New Mexico. Also worked mobile to mobile on New Zealand's South Island. Mobile does add that fun "edge" to long haul DXing and did I mention it is quite addictive as well. Plus, it is a great way to introduce Amateur radio to others...especially KIDS, so don't forget to use it to pass on the joy!

Had a contact last week with a sailor en-route from Cabo San Lucas, MX to Hilo, Hawaii. He was about 1/3 of the way there. I was rounding Cape Hatteras at the time, so total distance was about 3100 miles.

Ok - so I was operating maritime mobile, but mobile nonetheless!

I have worked so many countries from the mobile I cannot think of what would have been the farthest. However, one sticks out in my mind. Miles per watt ERP would have to be my mobile contact on 160m to Austria from Michigan using 100w from the mobile. With an ERP of 2w over a distance of 4500 miles, on 160m this is awesome. When conditions are good and you have a decent antenna, DX is easy from the mobile.

I can remember the last solar cycle working almost every point around the globe all within a couple hours from the mobile. Location and conditions is more of a determining factor than anything else. Any antenna that is better than a dummy load will get out when the conditions are right. True, an antenna that is more efficient will do better when conditions are marginal. However, even an a hamstick will do the trick when conditions are right. I would much rather have an antenna that will work all of the time, though, than to have one that is so-so.

As far as time is concerned: I talk on 75m from the mobile quite a bit. While mobile on 75m I have had my normal round-table with the group that I talk to. My mobile puts out good enough signal (running 100w) that I have pulled up to the house and just continued talking from the pickup -- why go inside when I am 10dB-20dB over S9 from the mobile. I have talked from before sunset to a little after sunrise to the same group on 3840kHz from the mobile.

I live in the remote mountains of east central Nevada, which makes having a good HF mobile a necessity; VHF is not very common and we only have a few repeaters, and none in certain areas, and none that work more than 20 miles from town; UHF does not exist; cell phones, yeah right. When you get 15 miles away from a town, forget it. At times you can be 70 miles away from a town, so HF is the only way to go. This is why in the day I run 40m and at night I use 75m.

It won't be long before some Ham will work a rover or something like that on Mars.
