I'm relatively new to this QRP thing.  I got into it a year ago, but then stopped all radio for 9 months (kids!). With my limited time, I'm quite happy how easy contacts have been. I expected long periods with no success, but that hasn't been the case.

I made a contact 2,800 miles distant with ten watts, which I know many of you have easily beat.... But that's my second best to date (3,800 Germany to New York is my current best).  I was using the Buddistick in a park near my hotel, the KX3, and a LifePo bat.

Anyway... Lots of fun! Finally building my Small Wonders SW+20 and I have the NorCal40A waiting in the wings with the theory book!

How's several hundred thousand miles/watt sound?

I was especially proud of my 40 meter CQWW CW contact with RC9O in rare zone 18 near Mongolia until I saw his antenna farm. I used 5 watts and a 43' vertical. He used...

My best was earlier this year with FT5ZM according to the N9SSA calc. is about 11,350 with 5 watts and a windom on 20m, which is about the same as Perth Australia. I have had several Qs with VK6 over the years. They were all on 20 and 30 meters with a variety of antennas - windom, HF2V, and HF5B.

Not my farthest 2X QRP/DX but my most interesting CONUS non 2x QRP qso was with K6KPH the Pt. Reyes, Ca. Marine Historical Society's commercial marine morse station from my Maine QTH, 3,280 mi. or a bit over 2,000 mi. per watt with my 1.5 watt 20m MFJ Cub and 20m homebrew Hex beam (24 ft.) and receiving their unique QSL card in the form of an old Marine Radiogram.

JKA, glad you brought this up. I have always considered my most satisfying QSOs to be between genuine off-watch MM stations on shore or at sea, plus significant Special Event stations such as Titanic memorial, Marconi birthday, significant radio/wireless commemorative stations for the occasion, etc.

Distance not an issue.

I remember way back in the 80's when 28.060 was teaming with NA-EU 2xQRP Qs. Back when 10 was 10 meters. What great fun!

I think my farthest recent confirmed (via QSL card) contact was VK3QD, 15,800 km, on 20m SSB, 5W, mobile, using an FT-817ND and a hamstick antenna.

Just for giggles I fired off a CQ on 15M with JT65 using the lowest setting on my rig which is 1.5w PEP and I wasn't using a ginormous antenna, but a compromise antenna, a MFJ-1786 magloop.  I was maybe expecting someone stateside to respond, but no.  ON6SAT out of Belgium came right back to me, which incidentally I ended up getting him on 10M, 12M & 17M at the same 1.5W!  4327 miles! In my opinion these new digi QRP/PPP modes make it all too easy now to go the distance, but it still is awesome how far we have come over the last two decades in infusing the home PC into amateur radio and the real game changer of SDR capabilities that have happened in just the last five years. Technological evolution is more and more fascinating the older we get..... Grin

Absolutely!

While I don't do digi modes much anymore, I started using JT65 about 4 years ago and was amazed at what could be done with so little power and "regular" antennas. My first two QSO's were a KH6 and Asiatic Russia, running 5 watts. I've used the JT-9 mode a little and had, if anything, even better results. I've heard a few guys say running JT65 is like watching paint dry but I think it's something that QRPers ought to at least understand and have in their toolbox.

My best QRP DX for watts per mile was mobile on 17 meters running 100 mW CW with a 559 report. It was Utah to Hawaii, so about 30,000 miles per watt. That's far from what others have done but it was fun.
