As some of you know, I have had troubles with my SCS DR7400 connecting to my ICOM 746 PRO
if power is lost to the modem.
Unlike the older SCS modems the new Dragons do not have a battery, so if power is lost all the
settings in the Dragons are lost for the most part except what is in the EPROM within the Dragon …..
The problem lies when BPQ32 is brought back up after a power outage, For some reason the
commands in BPQ32 will not reset the DR7400 to address the Radio, unlike the DR7800
which has no problem. Thus whatever frequency the radio is on, when the power outage
happens, is where the radio sits on frequency. Besides that, the modem will not answer any
calls and states it’s busy.
Ken KD6PG has written a simple script so it can be fixed by using a terminal program.
Using a Terminal program log onto your 7400 and hit return to get to the CMD: Prompt
Then type TRX:
Next type TY I 19200 104 Note: I is ( i )
This should set the 7400 to the ICOM at 19200 with a CIV address of 68
NOTE: CIV codes may very from ICOM to ICOM radios
Then type quit
Quit returns you to the CMD: prompt
This is only for the SCS DR7400 but may work for the DR7800 fi you have a problem
Hope this helps someone having the same problem as I am having.
