Thats the problem with this QRP syndrome. Everyone cherry picks the big guns, and does not give credit to the big guns antennas for helping them out.
You never hear a QRP station say. " I heard this good strong station with a attic G5RV and I called him and he gave me 5/7" Its very simple these kind of QRP QSO's with average ham stations are rare depending on what you call DX.
Its easy between certain locations. Examples are the East USA towards Europe. Signals routinely peg the S-meter on the short path. Try and the same QRP trick from California or the Mid West, different story. The long path is even harder. If you running a decent level of power like 20 to 30 watts which in signal to noise ratio terms is similar to a 5 watt CW you will have great success.
If you like setting and breaking records QRP at any low power is fine. However from a practical communication perspective, where you require reliable communications not pot luck communications 5 watts SSB is not a realistic power level. The low power contesting power level should be raised to something like 20 to 25 watts. Even with average antennas you can have consistent reliable communications. If you look at commercial HF radio systems over the world you will find that in many places the so called "jungle radio phones" operated at this power level It was a good choice for reliability on battery power. The same goes for HF military manpack communications.
Ham manufacturers could easily design 30 watts SSB battery/portable radios. Yes of course if you like QRP and conditions allow it nobody is stopping you from turning the power down and having some fun. I cant see
that picking a arbitrary power level such as 5 watts and just accept that you will fail 90% of the time. I prefer to have success 90% of the time and reliable communications. If I wanted a challenge that challenges the laws of physics,
I would go on top of the mountain and scream and then see if my voice reached South America. Under some circumstances operating with QRP power is just as ridiculous.
To WX7G and all...
You are absolutely correct on what you stated in your previous posting about 2 db stronger. I find that to be a good "rule of thumb" and I've used that for decades now....honestly, that really works. However, something I've found recently,especially on 40 meters night-time propagation-at least here at my Qth is to call stations who are well over S9 too. A good example of this was last night and last Thursday night on 7.163 Mhz. Tom-DF2BO--Yes! Tom the owner of Opti-Beam in Germany was 5by9 +30 to 40 Db here on my vertical array. He kept asking for DX from North America..."DELTA FOX TWO BLUE OCEAN With Company calling Cq Dx North America"....the usual kilo-watt stations were answering but the longer I listened to Tom stating that it was already daylight there in Germany and had been for an hour or so....I kept hearing stations farther West of me here in Upstate NY answering him and Tom giving them 5 by 6...7 reports. after hearing DF2BO for over a half hour here at my Qth I decided to give him a call. Tom came right back to me giving me a 5 by 7...8...he was still 5by9 +20....Tom was totally shocked to work a 5 watt Qrp station on 40 meter LSB. On frequency he had I5ZSS- Pat near Florence and GM2YSN-Ian in Scottland. I had worked Pat and Ian many times B4 and they both knew of my Qrp exploits. Pat gave me a 5by7 and Ian gave me a 5by8....Again, this 3 way with DF2BO, I5ZSS and GM2YSN happened last night and last Thursday night with the same conditions being well after sunrise in Germany and Italy.
And NO!! NO!! NO!! I AM NOT BRAGGING ABOUT MAKING THESE CONTACTS!!! SO DON'T TAKE IT THAT WAY PLEASE!!! PERIOD!! What I'm trying to put forth to ALL of you reading this QRP and SSB postings...is don't be afraid to call an S9+whatever station who's calling CQ DX outside of the country you live in. You may very well be pleasingly surprised that S9+++ station just might answer you because conditions are highly favorable between you two. The point I'm really trying to make is LISTEN to what the DX station is saying...I was TOTALLY SURPRISED when DF2BO- Tom stated that he had been in daylight there in Germany for well over an hour. I would have thought as in my past experiences on 40 meters that the DX Window usually closes shortly after sunrise for the DX station you might be working. Bottom-line is...as far as I'm concerned .....is to LISTEN to what the band conditions are currently when you're on the air. Propagation/conditions are NOT set in stone...I know I learned something from the 2 contacts with DF2BO and company ....LISTEN MORE.....OPEN YOUR MIND A BIT....THE SOLAR INDEX/NUMBERS DO NOT ALWAYS TELL WHAT BAND CONDITIONS TRULY ARE.
My BEST regards with many 72...73...
