Hi all, I cannot get my flex 3000 to go into TX when using DM780 it receives & decodes fine but won't go into TX.

my set up is DDUtil V3. VSP manager and VAC 4. everything is connected even the radio in DM780 is connected. i get the following message when closing down DDUtil.....object reference not set to an instance of an object at DDutil_V3.setup.processDSPfilters0

any help would be good thanks

    right folks the plot thickens, I still have the problem described as above, however when I use the full blown HRD programme & DM780 with in it I can both RX & TX with no problems I have the full blown HRD set up exactly as I have in when I am using DDUtil  com ports, VAC & PTT the same too.

    yet it won't TX when using the DDUtil programme, I just can't understand it.

    for the time being I will use the full blown HRD but seems a bit of a waste to have 2 radio Payne's going at the same time using valuable resources CPU etc etc.

    thanks Keith
