Hi
I used writelog in the ARRL RTTY RU contest last weekend and had a lot of
problems. This was my first RTTY contest using the flex, I have previously
used writelog for all my contest needs and like its operation and interface.
I also rather like the fact it uses IP comms to the Flex rather than using
DAX and SmartSDR Cat.
I used the following setup
Smart SDR v1.9.13.173
Flex 6500
Windows 10
Latest writelog version 12.12C Dec 2016
Writelog Flex driver - WlFlexDriver1203A (setup as single radio)
MMTTY as main RTTY interface using XMMT.ocx
Network uses a Gigabit switch between PC and Radio with cat 6 cables
Smart Cat & Dax closed (Except when I needed a PTT line when writelog
stopped PTTing then DAX and IQ channels used by WL driver were disabled in
SSDR DAX/CAT)
The problems I had were
1 - For no reason comms would start to drop packets (upto 30%) Rebotting
writelog sorted problem once. Other times the network issues persisted,
tried rebotting everything many times including PC
2 - Keying of the radio stopped and I had to Revert to using SmartSDR Cat
port in MMTTY setup to key rig.
3 - Intermittent operation of Focus helper
I also had the latest version of 2tone crash a few times in my clone
receiver.
It was running with less network traffic than my normal general logging
setup of DXlab and SDR bridge with a couple of CW skimmers running. I still
tried slaving the switch and network cables but that had no effect.
I was running unassisted in RU but for BARTG and WPX RTTY contests I want to
setup a RTTY skimmer to post to the band map. But need to sort out base
logging/RTTY software first.
I normally get zero packet dropped and latency <1mS
Any help appreciated Andy M5ZAP
