I did manage to get one frame from you Arthur, even though it was a healthy signal the interference won for the most part.
Sorry to hear about your antennas, i did that exact same thing many years ago, NEVER again!

There was definitely some tropo about as .750 was very busy all day.
Malcolm UHY, i heard you very well up to S7 for some time while you were working Dave.
There were were lots of other stations quite weak/readable but i couldn't raise any of them, nice to hear lots of activity, great!

Looking forward to the next one.

A really good day out. Thanks to all who participated!

I went portable about 20 miles West of Salisbury and managed to work Malcolm G0UHY at at 119 km, David M0YDH/P at 154 km and Dave G4FRE/P at 118 km, all on 70 cm. Closer in I also worked Mike G8LES at 87 km having seen his pictures before even hearing him on talkback. Some work to do on the 5.6 GHz kit which I took along to test but seems to be very insensitive on receive.

Please don't forget to submit your entries to contests@batc.tv.

Dave, G8GKQ

Close, but no cigar......not helped by leaving my Minitiouner behind - I did have Plutos to use with DVBS_Gui but neither laptops could cope with details for 146.5 and obliged by crashing after 30 seconds. SDR RSP1 was present too, but not with its required USB-B lead. One day I'll take everything I need.....
1kW ERP on 5.6GHz FM didn't make it to Dave but it all seemed to be working. My new full-wave dipole for talk-back on 2m worked well, being heard on the Yorkshire moors and down in Taunton (suspect some tropo help).
Did work G8LES one way for a first and only contact.
Some observations as a relative newcomer....144.750 is too busy for effective calling - do we need to agree a QSY off once a new station is found?
When posting activity, could people include the name/location enough for Google to find it rather than just the locator. At the moment I'm looking at the distance and direction using Google maps. Maybe there's a better way (I think some contest software shows distance and bearings based on locators entered, maybe there's a better way - please share!)
SIte was nice and private (by paid for arrangement) and offers good takeoff to the north, via West round to South. For the future I may be able to move a bit to clear the trees where it is at least clear (but flat) round to the south.

Gareth,

If you have an Android phone use LocatorDroid for bearing and distance, it knows where you are from GPS ref.
