This is a great topic. I worked Japan last night and Moscow this morning, coming home and heading to work, respectively. I am running 25 watts and loving every minute. Likesaid before, it seems that by being a mobile allows you to break through a bit easier.

NICE! Smiley

Just worked this morning via mobile QRP at 500mw (milliwatts) a Russian station with 5/5-5/7. There was a pileup for this guy.

Yes...calling QRP or mobile in some cases gives you a slight advantage but not as much as you think. Very low power, inefficient inferior antenna and low altitude and you still need to be heard. To be heard at 5/5 and 5/7 at 1/2watt in the pile up is huge when others are running 100+ watts and 1/2 wave resonant antennas up high.

Actually, depending on the band you're operating on the efficiency of mobile antennas can be pretty good. On the higher bands efficiency will be quite high. For example, on 160M my antenna has -9.7dBi gain but on 10M it has close to 4.5dBi gain.

But great job on the QRP - that's a great achievement!

I worked the azores while mobile QRP.I was using a ft 817 into a 20m hamstick mounted to the bumper of my jeep rubi.I broke a pileup and got a 57 report all from Rapid City SD.We did not carry on a conversation just exchanged reports and location,it sure excited me.

It is exciting! Keep it up trying different antennas and you'll see it get even more exciting. At 5/7 report you could've had a nice lengthy QSO if you think about it.

Australia and Japan using just a little Radio Shack HTX-100 in the mobile, 25 Watts SSB with a 9 foot whip!  What a treat!  Smiley

Longpath from central Oklahoma over the Pacific over the Indian ocean over Africa and out into the Atlantic. An Island near Diego Garcia. Via the Mobile.

The path was verified by Jack W1fdy the Southern Cross dx net control net operator at 14.238.

A few days ago 10 meters after our (Texas) sunrise opened up LP to southeast Asia. Quite unusual as I recall. I worked a few from the mobile, but east coast was having a field day ! My Hong Kong LP QSO was reported on QRZ as 16668 miles.

Wild 10M LP to Asia in our morning !

93 miles on 2 meter with 75 watts and a 5/8 wave antenna through very mountainous terrain.

Mobile HF has been a BUNCH of fun the last few months!  I was driving home from work the other day, and the best signal I heard was C50C.  Worked 'em on the first call, and that was my first C5 mobile!  (It was a great op at C50C, too--handled the pileup very well; efficient and good ears.) What's more fun than working DX from the car?  :-)

I get the opportunity to work a fair bit of mobile and portable DX with 100W, VK/ZL regularly in a morning on 20m long path, ZL on 40m in the morning long path and East Coast USA around 05:30hrs. 4A4A Revillagigedo Island is my furthest on 80m some 5,800+ miles, plus a number of contacts to East Coast USA.

I was backpack mobile a week ago on 20m with approximately 80W, amongst the many VK and ZL contacts was one JA long path, some 19,068 miles, I could kick myself for not trying a QRP contact as I was 58 with him, I could easily have done this with 5W. My best backpack QRP contact is VK7 with 500mW 13,960 miles, the same morning I worked ZL2 13,306 miles, however 500mW was a little difficult, but Q5 with 2.5W.

Not strictly mobile, as the FT817 and miracle whip were on the roof of the car Cheesy but I managed to work WA6 with 5W from the Island of Crete, SV9, in October on 10m, 7,113 miles, I also managed to work VE1 and W0 with 500mW and the same equipment, October was exceptional Wink

Timing, persistence and technique should see most people working good mobile DX, exceptional mobile DX takes a lot of hard work, VK on 160m is the new challenge, courtesy of G4ZOW Wink

Edit:  I had a chat this morning with ZL3JAS/M for an hour, so I guess that's my longest lasting long distance mobile to mobile QSO Wink

A few days ago I had a good QSO with KP4BI (Puerto Rico) which is 10,000 miles+ from my location in Thailand.  This was with my MFJ 20 meter band rig and about 100 watts output from my linear into a Hustler resonator on my car roof.

This was working the grey line.  But perhaps the fact that I had parked my car only 5 meters from the Indian Ocean would certainly have helped Smiley

Now, that's a good one! Puerto Rico is fairly easy for me. But, I have not worked
Thailand yet. Maybe one of these days!!

Back in the late 90's I was headed to Ft hood Texas from Abilene, running my FT-726 mobile with mag-mounts on 2 and 6 meters. Listening to a dead band on 6 and all of the sudden I heard Arnie Coro, calling CQ on 6. If you aren't familiar with Arnie, he has been a fixture on Radio Havana Cuba for years with SWL and Ham Radio programs.  so it was a good contact for a minimal station, and a thrill for a former SWL turned Ham to speak to Arnie Coro!
