Does anyone know how I can convert the output from a speaker/headphones jack
from a Laptop into a suitable input to the Mic socket of a TS430S? It's for
running SSTV

I have not been able to find anything on the net - probably 'cos I'm asking
the wrong question.


have u actually tried connecting the output of your speaker directly
into the mic input? i bet you a 2n3904 that it would work. you can cut
down the audio output using the volume control applet.

even if you do horribly overdrive the transceiver, you dont have to
sweat because the SSB filter will clean out any out-of-passband
distortion. and sstv does not use any amplitude variations (i am not
aware of the newer SSTV modes) so clipped audio will not be very
different to the remote receiver.

as usual, i guess, you should simply plug in the sound card output
into your mic input to see what happens.

i have used my homebrew on PSK31 without any attenuation. it works
pretty well. infact, i got into PSK31 by hanging my PC's mic over the
speaker box and tuning the sigs using WinPSK. On a dare, I left my
transceiver mic on top of the PC's cambridge work speakers and started
working PSK31 dx right off. the next night i searched around for a
pair of cables and connected the rig and the PC together without any
other components.

i have used RTTY, SSTV as well as PSK31 without any electronics in
addition to ordinary cables.
