It was a total pleasure to operate in CQWW RTTY, the first time using a Flex in a RTTY contest. (Single op. unassisted) . Seems to me that using a Flex may need to get re-classified as "assisted" since it was really easy to work lots of stations search and pounce. I did not operate more than 5-6 hours on Sunday , but the few hours I did operate were so EASY.
I assume it is "old news" to regular Flex operators, but for the newcomer , here is how I set things up. I configured N1MM as per the usual instructions using VSP amd DDutil (Google this for info). I set N1MM to use MMTTY as the RTTY interface. I selected DIGL in PowerSDR and also selected a 300 Hz filter. In MMTTY/N1MM I set AFC to "ON". With the 300 Hz setting with AFC I had absolutely NO issues in then simply clicking in the middle of the two vertical lines in the Panafall and finding the station tuned in well enough to instantly start decoding. No "fine tuning needed". I used the "2X" setting in PowerSDR most of the time, "4X" worked well also. "1X" "0.5" gave you more spectrum to monitor, but the detail was too small to really differentiate between stations. I did run in to a few issues that may be related to latency but nothing major. Maybe I need to adjust some buffer settings. Quite a few times , after I had stopped transmitting, I would see may call sign then scroll across the N1MM screen. A few times I incorrectly thought it was a station coming back to me . Example 3UK G3RK de P5DX Also, a few times, a station responding to me could be heard stopping their transmissions but there was a 1-2 second delay for what they sent to appear on my screen. This only happened a few times , so perhaps my PC was a little sluggish at times. I'll work on the settings for next time. Lots of fun, Andy K3UK _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
