I went to Portsdown Hill (where else?) with the demo Portsdown transmitter. I worked G7JTT/p, G8LES and G8GTZ/P on 146 MHz, G4GUO on 437 MHz, and G8GTZ/P on 10368 MHz - the best catch of the day at 62 Km.

All contacts used the Portsdown Transmitter with appropriate PAs and Transverters. Receiver was a Sharp tuner, Minitioune 0.6d and an SUP 2400, again with appropriate preamps and converters.

In addition, I know that M0DTS, G0MJW, G4CPE, G4KLB, G8VAT, G8VDP, M1EGI, G8VDP and G3NWR/P were active. Was there anybody else out there?

Hi Dave,

Yes I can report activity Saturday and Sunday between G0WFT, M0SKM and G3KKD. 70cms 333Ks/s Saturday and 70cms 2Ms/s Sunday.

Anyone else was either too far south or north. I did make an unsuccessful attempt at 23cms analogue with M0DTS on Saturday morning :-(


Ian Waters G3KKD pictured Sunday afternoon. 70cms 2 Ms/s over a 62K path.

G7JTT/P - IO91JA 39Kms - One way G8GTZ/P tx 2ms

Great fun :-)

Looking forward to the next one - Question, should we make it a monthly event from March to October?? Just seems a long time until May when the NB contest season begins and the next planned activity day...

As G6NOI and I arrived at Rhosesmor, North Wales, the rain started. It wasn't very heavy, but the blustery wind made for an unpleasant afternoon weather wise. However the activity made up for it and all our contacts were on 3cm.

The tx equipment was a 'Solfan' / DG0VE 500mW PA / 15dB horn combination. The rx system was an Octagon LNB with a 26MHz crystal, 60cm offset dish and a MiniTiouner (Sharp) / Pace MSS508.

The cunning plan to dispense with CRTs for analogue succeeded. The output of the Pace was connected to the DigiLite transmit system through the HVR1900 MPEG-2 capture box and viewed on the laptop.

Except for G4CBW, all transmissions were analogue.

Received by G3UVR at 14km.
2-way with M0LCR/P at 31km.
2-way with G7MNP/P at 31km.
2-way with G4CBW at 65km.

G4CBW was running about 10W to a 1m dish at first. We received him on the LNB alone and also on the dish with very low power. This was our first reception of 3cm digital. We look forward to trying longer paths. We also tried transmitting to him vertically on 2m. The signal was very strong, but would not lock, presumably due to lots of multipath.

We heard M0DTS and G8VDP on the vertical on 144.750MHz. In the end, time was pressing on and the weather had sapped our strength to continue. An enjoyable day overall. Thanks to all who took part.
