Well I’m all kitted out for mobile PSK31 (and more now) Gawd… another 1.5kg to heave about! I intend to get out this Sunday (you watch the wx turn awful now). Not quite sure where and when, that still depends on the wx and my legs. But a possible pairing is Ben Each SS-034 and Stuc a’Chroin SS-010 or Meall Bhuide SS-060 and a tiddler on the way home.
But I want to sound out a few ideas that I hope will help make digimodes a bit easier. Of course with the way the bands have been I should be so lucky to get a pile up, but, for once we GM hams have the advantage that many of the chasers are 200+km away minimum. This helps on 60m certainly.
Assuming that there is some propagation and that anyone wants to work me, I think it would help no end if anyone answering my digi CQs does not answer me on my TX frequency. With the way things have been and following on from Barry’s comments in his Caterpillar bull, many chasers will not be able to hear each other. If you all netted onto my TX and replied at the same time then I’m not going to be able to pick anyone out. From experience, unless one signal is massively louder than all the others, you cannot pick out one PSK signal from the others, unlike when listening to SSB/CW. So spread out. RX bandwidth is from 300-2500Hz, so if I’m using an audio frequency of 1000Hz, there’s a huge amount of space for people to answer on. Pick a frequency and stick to it. I’ll work splits with my TX frequency fixed and I’ll tune about on RX. Possibly I might use the beacon frequency for digimodes. There’s loads of space around the beacon CW freq. and maybe a few non-SOTA types may hear me too.
If anyone has any better suggestions then I’m happy to listen but I think that things should work OK with this kind of split. I’ll be trying 80m and 60m primarily. In fact since I found that on the 817 the preamp and attenuator settings are stored per band, my 80m rx seems much livelier. Yes I had the attenuator off and the preamp on on 60m and didn’t realise that they were they other way round on 80m. No wonder the band seemed dead the last few times I tried!
Tests suggest that I should be able to get at least 1hr battery life on the digital side. It will be interesting to see how the SLAB holds up on the 817 with the 100% duty cycle. Of course I’m looking forward to see if I can qualify a summit on 0.5W only. That would be extra special.
