G4FRE to G3VKV fixed station tests
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 http://g4fre.com/DATV_G3VKV.htm

Re: G4FRE to G3VKV fixed station tests
I'd be interested to see/hear about the antennas you were using....

G4FRE to G3VKV fixed station tests 6cms
The 6cm path has now been completed at the second attempt after slight increase in antenna gain at both ends to overcome multipath issues
G4FRE used 5W + indoor 21dBi panel antenna+DB6NT Xverter+Portsdown/minituoner
G3VKV used 1,5W
next band 13cm

G4FRE to G3VKV fixed station tests 13cms
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!

G4FRE to G3VKV fixed station tests 23cms
The last band to complete the sequence!
G3VKV (45W to 20 element Wimo Yagi) as received at G4FRE
G4FRE (8W to an 23 ele tonna on window ledge, you can just see the elements of the yagi outside the window) as received at G3VKV
Thats the completion of 2 way fixed location to fixed location DATV QSOs on 7 bands! The complete history of the qsos is recorded at http://g4fre.com/DATV_G3VKV.htm
