Take your time and be patient. You’ll be an expert in no time!
Last year, 22 logs were submitted. Lee, N5SLY, won Top Dawg honors and First Place in the 50W category with a spectacular 79 QSOs utilizing all 6 modes, and a score triple that of his closest competitor.
Let’s see if we can give Lee some competition this year !
Hope to work you in all 6 modes

For 31 Flavors, there are lots of good suggestions embedded in the contest rules.
RSID operates by sending a short burst of a specific modulation before the data signal, which can be used to automatically identify over 272 digital modes. This burst consists of a 10.766 baud 16-tone MFSK modulation where 15 tones/symbols are sent. The burst occupies 172 Hz of bandwidth and lasts for 1.4 seconds.
Using the RSID is a great idea. Just make sure if you make a contact to turn the RXID off during the contact because if another RSID is received while you're in the contact your rig might switch to a different mode and you'll loose the contact..
That will not happen in DM780. You must click the little notice box for the software to change frequency and mode.
