We discussed RS ID quite a bit when first developed but only being on Multipsk, it was not that popular. From my testing a year or two ago, I can confirm that it works extremely well and there is nothing really technical to understand.
The RS ID transmit, adds a burst at the beginning of each transmission that has the special coded information. (Fldigi adds the burst to the beginning and ending of each transmission). Then there is a corresponding RS ID receive that decodes the burst, switches to the correct mode, and can move your waterfall frequency to the RS ID frequency within a few Hz. This can be of great benefit for modes such as MFSK16 which require very close tuning, even with AFC. I would like to be able to easily turn off the transmit feature, since once you make the contact, you don't normally want to to keep sending RS ID transmissions due to the time it takes to send the burst(s). The transmit ID's can be nested several layers deep in the menu. My understanding is that the RS ID receive is turned off automatically once you are "captured" by the other station. Otherwise, you could get captured by someone else right in the middle of a Q and moved to another frequency and even a different mode. I couldn't find information on HRD/DM780, but the Fldigi information is at: http://www.w1hkj.com/FldigiHelp/ConfigID.html 73, Rick, KV9U Phil Williams wrote: > > > I agree with Andy's recommendation.
