Thread-topic: Amazing night in LF. South Dakota at 7660Km in WSPR-2
HNY Spiros, LF

Sorry, I'm still not ready for QSO. This week I will be back at Tx QTH and have to
install PA at top terrace, check downconverter for Tx in LF, etc. But don't worry
We will do it ;-)

BTW. I mentioned in this reflector time ago, that I was observing an strange LF antenna effect
Tunning the antenna at resonance with VNA did not match with the optimal resonance point when
transmitting. I was puzzled with that untill discovering some nearby metal parts heating up during
transmissions. The chinese IR thermometer gun did his job here

Once removed the metal parts, resonance in Tx matchs now with VNA readings and all is much easier
I'm running 3A RF and PSU at [email protected] I have to test WSPR-15 again and when getting the last U3S
firmware finally combine transmissions in WSPR-2 and 15

The only way to convince SWLs to run WSPR-15 instances is to put a signal on air and compare results

Hi LF
 
Last night didn't start with good DX but seems that conditions improved later on
I have got decodes from a new one, K4RCG in Virginia. Also Wayde and Paul reported me

But the most amazing was an email, from Arliss, W7XU, in South Dakota at about 7660Km !!
He has been decoding me four times around 02 UTC with signals from -28 to -31
I have asked Arliss to upload the data to wsprnet, but in the meantime, this are his reports
