Use of RsID during digital nets
|
We have been working with a group of our ACS members to develop some expertise in HF fldigi\/NBEMS. I was hoping this group could provide some advice on the use of RsID/TxID so that we don't chase each other around the band. About 10 years ago I used fldigi/NBEMS extensively for tracking runners in trail races but that was mostly using MT63 on FM.
My thought was to have the NCS transmit TxID with locked transmit frequency during the preamble then turn off TxID. Net check-ins would use RsID to sync with Net Control and then lock transmit and turn off RsID. Does this sound correct? Thanks, Bob AF9W |

The Feld Hell Club's nets all run with NCS having TxID on the entire net so anyone can join on the right freq. even if they are late to check in. NCS also has locked it's freq. The other stations on the net should use RxID to sync with NCS. It is up to them if they leave it on or not, but normally it should be off if already synced with NCS. The only advantage to leaving it on is if the net needs to move due to QRM is would be useful to again sync everyone. It is important that the RxID is not setup to automatically jump freq/mode, but to only notify of the RxID reception details and leave it to the station to jump or not.

Thanks, Cliff, makes sense.

Bob... @ ORCA DIGITAL NET, NCS runs TxID ON; members have it OFF except when changing mode for traffic or comments. Unnecessary TxID adds time to a busy net w/o benefit. It also adds noise to the log. NCS has TxID active, so incoming Ops can easily determine net-mode throughout the net. At Ck-In, members transmit a brief Pre-Tone b4 text w/TUNE Button, warning others that a transmission is eminent. Monitor a couple ORCA nets to see how efficiently this works. If you can't copy us directly, use an SDR. We encourage members to think of TxID like turn-signals that don't self-cancel. You want to be mindful of their state, turning them ON/OFF as needed. This helps build Situational Awareness and efficient digital operating tactics. NCS & members have RxID ON.
Pre-Toning when doubles are likely avoids avoidable doubles, enabling fast and efficient net operations. When NCS calls a member station directly, Pre-Tone is unnecessary. We've been using these tactics for 10yrs with excellent results. We've checked in as many as 41 stations in 30min. Our nets run very efficiently and we pack a lot of practice into an hour.
