With the upcoming Hamworthy Park Festival I wanted to see if there was any chance I could reach the QTH. Previous attempts from Poole Harbour were unsuccessful with FM and the Bongos whip antenna, but having a new antenna in the armoury thought I’d give it a try.
I had already tested from the drive way of my QTH, then headed out to what is the nearest high point to my QTH in IO90BS, that of Ringwood Road near to the Matalan – IO90AS. A test of the SSTV repeater there worked well.
I then headed down to Hamworthy park, as I drove through Bournemouth and Poole the hills behind me which I knew would absorb my weak signal, but I’d thought I’ve got to give it a try.
I had the hand-held antenna quickly setup, it was fun to do it out in the field. I attached it to the THD7 and tried to reach the QTH station.
I was not surprised to not hear the pips back to transmit, but as I had driven there, transmitted anyway to see if anything would be received. I wasn’t expecting anything back as the replay mode hadn’t kicked in, so I would have to wait until I got home to see. Sure enough I had received something, albeit mostly static, but at least the application and radio could pull the signal out.
APRS Provided some interesting information. My route was entirely captured, this is due to the geography of where the APRS stations are located.
If I compare my APRS packet reception to my location of the transmission from IO90AS, the APRS station is just down the road near to Bournemouth University.
As soon as I go over the hill, all my packets are received from stations to the east.
The hills between each location are clearly visible using the useful line-of-sight tool.

So it was great to go out and test, albeit the transmission back to the QTH from Poole was again not successful I was able to gain valuable experience and APRS packet data. I think I will be able to setup another solution utilising the Bongo’s 2M whip antenna and a small laptop for the actual Hamworthy Park Summer Fete, so will put those pieces together and test those out next !
Until the next time – 73s
