In reply to EI8FDB:
Nice one bernard. I use cocoaModem too, I don’t find the interface all that intuitive and I’ve yet to figure out how independently set the frequency of each receiver and I can’t see a way of including LF/CR in the macros, which is a shame. Perhaps I’ll get my head around it. That said, it is a very good program, especially for free and I’m glad someone has done something good for datamodes on the mac.
I had already looked at the iMic, indeed, even looked on ebay for them. I am however, one of those penny-less student types, and even at ebay prices, I’d sooner not spend the money =) Fortunately I recently upgraded to OSX 10.4 and the in-built driver for my c-media USB soundcard includes support for attenuating the mic input level. Problem solved!
Yesterday I managed to get on the air with PSK31 and my ibook. I am at the home QTH in Worcs ATM, not at my Uni QTH in Bangor, where my Rascal GLX interface is. But I did manage to use a simple jack-to-jack cable for RX and lashed the mic to a pair of headphones and switched on VOX keying for TX, hi. It was just proof of concept, and it works =) I’ll put everything together a little better (Rascal interface, RS232 adapter for keying etc) when I get back to Bangor. When there is a fine day an 80m PSK31 activation should not be that hard to pull off (famous last words).
