at 1800Z 20 seems to be open into the mid west, eastcoast and westcoast. Anyone up for playing with DominoEX? I'm on 14072.5 listening while doing some other work John VE5MU
Re: [digitalradio] Domnio, PAX etc
W1OER was on 14.073 just now so worked him and chatted a bit. He was calling in DEX11/FEC and I was set up for DEX11 w/o FEC. And then realized that I was actually on FEC because I had the RS ID Detect turned on. 73, Rick, KV9U John Bradley wrote: at 1800Z 20 seems to be open into the mid west, eastcoast and westcoast.

Re: [digitalradio] New Rig!
Welcome to the TS2K Experience, Andy! You'll enjoy this rig as you begin to understand it's many features. It's a great digi rig :-) . As another email noted, take a look at using the packet filters (menu 50A). I think you use HRD and you can do macros in that app similar to MixW2 to enable and switch the filters. I use that almost exclusively (instead of the Lo- and Hi-cut filters). The best is to experiment with it and see which works best for you. 73, Larry (NK2X)

Hi Rick, Just FYI; you and Dave (K3GAU) were solid copy on DoiminoEX on 160 tonight despite me using my 80 meter antenna. Actually seemed best using 22 baud with FEC...one or two static crash hits, but overall impressive considering my antenna limitations on 160 meters. 73 Bill N9DSJ --- In digitalradio@yahoogroups.com, KV9U [EMAIL PROTECTED] wrote: W1OER was on 14.073 just now so worked him and chatted a bit.

Bob, I re-posted this on the HSMM list too ([EMAIL PROTECTED]). Thanks and good luck! John - K8OCL
[digitalradio] Re: Domnio, PAX etc
Well can only relate my impressions; hope others chime in I think even though DominoEX halves the speed when FEC in engaged, it is well worth the speed trade-off. 160/80 seems to vary night to night in this regard; probably due to qrn and multipath. It also depends on one's ability/willingness to read between the lines as there are a few hits at the higher speeds and one needs to brain- error correct as there is no ARQ. As for Throb; I find it very sensitive, but at times it does not seem to decode signals that are audiblenever figured out why. As for MFSK modes, yes they are very frequency sensitive although I have had little trouble tuning most, aside from a few that took a long time to sync. Multipsk's AFC seems to lock quite well on MFSK signals, not sure how other software doescertainly DominoEX is superior in that sense. I have not worked enought MT63 to comment. I have had better luck with CHIP64 although both seem to not be qrp modes and require a high signal to noise ratio... It is odd (but probably not so if studied correctly), on some nights (condx) certain modes just seem to work better under various conditionsat times I am amazed that Olivia can decode signals in the mudother times I swear at it...one night on a VHF path only PSKAM10 or JT65B would get through; guess that what makes it all fun. 73 Bill N9DSJ --- In digitalradio@yahoogroups.com, KV9U [EMAIL PROTECTED] wrote: Hi Bill, Yes, busy night tonight on 160:) The question I wanted to ask the group was whether they have found on the lower bands (especially 80 and 160) that DominoEX (DEX) is better when operating at a given speed such as DEX11/without FEC or is it better at twice the speed, but with FEC, e.g., DEX 22 with FEC? Tentatively, I almost want to say that it may be better at the higher speed with FEC. If true, and I am not sure it is, it could be because the higher speed still has a fairly low baud rate, even for some serious multipath on the lower bands. The 77 wpm speed with DEX22/FEC is faster than is comfortable for keyboarding so a slower speed is not bad. The DEX11/FEC does seem quite robust, even with static crashes and who knows how much multipath. Of course you can never get 100% copy under certain conditions when too much of the data is damaged and the Viterbi decoder can not reconstruct the character. Then an ARQ mode would be needed. I wonder how well this type of mode would work with a PSKmail type of program? I know that I had a very difficult time reading a PSK31 signal that was up the band from me. The earlier station that I was talking with for our weekly sked for experimenting with these modes at a short distance of about 35 miles or so indicated that he had good luck with MT-63 in the past but the faster (wider) mode seemed to work better due to having the data spread out so far. Has anyone else found this on the lower bands with MT-63? The ability to only approximately tune in DEX signals is extremely helpful for me as I find that I have a difficult time locking in on MFSK16. Earlier tonight WA9HCZ and I started our experiments with ThrobX and although he could copy me solid, I could never decode his signal. So I must have been doing something wrong. Ideally, these modes that need extremely accurate tuning, should have some kind of display to help you determine if you are far from locking in to the signal or not. Something like we had with the early PSK programs. 73, Rick, KV9U
Re: [digitalradio] Re: Domnio, PAX etc
With respect to MT63 , I have used it extensively in the past and found it wanting, especially trying to tune a weak signal under less than optimum conditions, as the noise covered the audio up. Under side by side tests it did not copy as well as Olivia (1000/32) . probably half as well on the day tested between 2 stations 1500 miles apart on 20M . that day likely a 2 hop. MFSK is fussy to tune, and with some folks using older rigs, is subject to drift during a long TX at power. Does get through, however, as well as OLIVIA 500/16 , and much better than PSK31, again trying multiple modes between distant stations. DEX? I always seem to be in the wrong place at the wrong time, so have only used DEX locally. Look forward to playing with DEX over a distance Will sit on 14073 center freq in the AM and please let me know if you are playing on 80 or 160 . Monday night had some good luck with OLIVIA 500/16 over a considerable distance on 160m tnx John VE5MU
