Hi All Having just moved house (& country!), and set up the HF radio gear for the first time in quite a few years - I'm having a dabble with PSK31.
I suspect that I'm having problems with poor isolation between the radio and the PC - at the moment the 'quickly knocked-up' interface is 'direct' - no opto or transformer isolation. I can read the PSK31 quite nicely (using DigiPan) - and load up the TX on low power (10W) - but higher TX power seems to generate odd squeaks and general instability.... ...also - I have yet to get a reply from any other station on PSK - which makes me wonder if my signal's getting distorted past the point of readability ? Does anybody have a source for 1:1 audio isolation transformers ? I can't seem to find them from the usual suspects (ebay, CPC...?) - would need to be an organisation that ships to Ireland..... Many thanks in advance Adrian - EI5JV
