[Moon-net] 2xWSJT and Linrad+SDR-IQ in the same computer

[Gabriel - EA6VQ]

Yesterday I was QRV on 144 MHz. EME for about 10 hours and experimenting the
whole time with a configuration that allows me to run simultaneously two
instances of WSJT and Linrad in a single computer (I don't want to have more
PC making QRM in the shack...hi)

One of the instances of WSJT was getting its audio input from the mic line
of the PC and it was also used for transmitting, with my conventional
station (TS-790)

The other instance was getting the audio though VAC (Virtual audio cable SW)
from Linrad and the SDR-IQ, and it was only used for looking for other
stations in the aprox. 160 kHz band I was monitoring.

To my surprise everything was running perfectly. The CPU load of the PC (a
laptop with a Core2Duo, 2.4 GHz, processor) is normally below 30%, except
when both WSJT's are running the decode simultaneously, but even then the
decodes were pretty fast.

I'm also very satisfied with the RX performance of the SDR-IQ + Linrad, that
is aproximately the same than with my traditional setup (sometimes even
better).

It was great to be CQing on a frequency, but being able to monitor the whole
EME band during the RX periods.  You never get bored when nobody answer your
CQ...hi    It's not like MAP65, but so far it's a noticeable improvement.

For those wondering how can I have so many windows open in a 14" laptop, the
answer is that I have a secondary 22" monitor connected and that I use both
at the same time.  If you want to have a better idea you can have a look to
the RF+AF diagram of my station at http://www.vhfdx.net/safont_sch.html

Many thanks to Leif for his support, correcting the mistakes of my initial
tests, and also to VK2KU's for his helpful pages.
