[UK-CONTEST] RS232 1 Radio / 2 computers

[G3SJJ]

Be interested to know how it works out Callum.

Big knob / little knob technique has been common in CW and SSB Field 
Days for many years now, and also at GU8D in the IOTA Contest we have 
done that on the Mult station. The second (little knob) computer is 
connected to the network but not the radio so we had to make sure we 
were always on the same band/mode as the main VFO one. I think we lost a 
few Qs one year in IOTA because Mult 2 computer hadn't kept up with the 
band changes on Mult1 ie main VFO. The UBA report indicated some "Not in 
log" Qs.

Last year at GU8D we instituted in-band / same mode multing which would 
have worked if not for the Shitelog/ mHam Router problems. So if you are 
running on 20CW for example, little knob op looks for 20m CW mults, and 
the Mult station looks for 20 SSB Mults. We are hoping to try it again 
this coming weekend at G8D at my QTH. It would be nice though to have 
the little knob computer able to poll the radio.

N1MM now fully supports both RSGB CW and SSB FDs. The scoring and mult 
indication are good, although at a cursory glance it didn't seem to 
count own country as a mult. See what you think.

Aah, you also need the patent GU8D SR2O switcher!! Quite simple bit of 
logic. Each op has a headset, whoever hits the foot switch first grabs 
the mic.  And no,  you can't have the cct.   But it will be in use at 
G8D on our Run station, cos it's good!
