G4FRE to G3VKV fixed station tests

Last Thursday night I had a 2 way fixed station real qso with G3VKV over a 26km path on 9cm
Both sets of antennas were indoors, pointing out of windows, both stations running around 5W
In the latter half of last year, G3VKV received me on all bands 144MHZ to 24GHz. We are now trying to complete 2 way qsos on all these bands. So far we have achieved 146, 437, 3402 and 10370MHz qsos The results are at my webpage

I'd be interested to see/hear about the antennas you were using....

G4FRE used 5W + indoor 21dBi panel antenna+DB6NT Xverter+Portsdown/minituoner
G3VKV used 1,5W

Today we completed a QSO on 13cms. Easiest band so far, signals good enough for 4MS/s

G4FRE (10W to indoor 20db panel antenna) as received at G3VKV

G3VKV (12W to 40 ele Wimo antenna) as received at G4FRE
Biggest challenge was dealing with the local WiFi signals. Ended up with 20degree uptilt on the panel antenna to null them out!
