Thanks for the update Olivia.  Although, I'm sure Mike was looking forward to a night in the bush....

Re: KK6MC/r activity

KD,

6M SSB starts at 50.125 and goes up from there if the band opens up. The segment 50.100 to 50.125 is reserved for DX operations, technically for intercontinental QSOs but you will hear XE stations there if there is prop. 6M CW is pretty much confined to 50.090 to 50.100 though you may find a few stations working below .090. 50.090 is the official calling frequency but I often hear stations calling around 50.098 +/-. 2M calling frequency is 144.200, you'll find both SSB and CW there.

Good luck. Try to work the rovers when they change grids. You can work them each time they are in a new grid.

Duffey,

No, it made it I was late in seeing it and asked just before I saw it in my cue.

Yes, the EME array has better gain than the stacked yagis, judging by the radio check I had with W9RM.

Will track you and Mike on 2.  Sorry I'll not have 222 through 1296.

Have fun es 73 Bill

end of contest, if we are early we will operate a bit here


WB2FKO whose home station is dismantled in preparation for a move will be operating with me. While we are dedicating most of Sunday morning to MSK144 we will operate FT8 and FT4 when in the other grids. WSJT-X while roving is new to me, so I am still feeling my way around, but we plan on spending roughly the first half hour at a grid on SSB & CW, then the next half hour or so on FT8/FT4 and then what time remains at the end back on SSB and CW. If we get behind schedule we will try to leave on time, which may leave us short of operating time at a grid.


When we have cell access we will be on Slack and APRS.

A random observation...

There is troposcatter and then there is tropospheric ducting, which is what most VHF+ ops from east of the continental divide (and some west coasters) are familiar with, when 2M and above 'opens' over paths exceeding 3-400 miles.

While troposcatter is a useable propagating mode most anywhere and accountable for a good majority of those 300 mile Q's on 10M and above, tropo ducting is another animal altogether and rarely appears in areas of drastically variable terrain like central and western Colorado.  The temperature inversions that often (always ??) cause ducting to occur are usually at low enough elevations that they are blocked by high terrain.  Plus, inversions go hand in hand with atmospheric moisture content, something hard to come by in the dry southwest.  My current humidity here in DM58 is 15%, which actually is high for this time of year.

I was referring to the Olathe-Amarillo path. Tropo losses rise steeply beyond 300 miles. Six and two are not too different with respect to the plot below. Meteor scatter starts to overcome tropo at about 350 miles, depending on station capability. WSJT-X helps, but at those distances MSK144 is probably better than FT8 or FT4 for that path. Typical modest station capability on 2M is about 200dB, less on 6M roughly by the difference in antenna gains.

The difference in large part is due to the height of the scattering media; for troposatter it is about 35,000 ft or below, for meteor scatter is it 60 miles or so. - Duffey

Re: Troposcatter & ducting

Keith Morehouse
 

I do.  Until 6 years ago, I was able to take advantage of it.

I recall a bad cold wave around Thanksgiving one year, when the Great Lakes were still warm and ice free.  A duct set up over the lakes and up the St Lawrence valley that allowed me to work K1WHS in Maine on 2, 222 & 432, along with VE2's from EN52 - well over 800 miles.  And, 2M QSOs all the way to VE1.  On 432, I was using a single 9WL yagi at 40' and 200W.

I also had a 'everyday' range of close to 400 miles on 2M troposcatter with a 5WL yagi at 75'.  Well set-up rovers could be worked out to 300-350 miles on 6 & 2M.  That's actually not too much different from what I see here in DM58.  Unfortunately, many local rovers are just not set up for longer haul stuff like they were in the upper Midwest.  They mostly have a 'work local' attitude.  You would never see serious rovers in IL, WI or MN counting on loops for 6 or 2.  The easily worked 6M rovers ran full size antennas, even if it was just a dipole or beam driven element.  It made a huge difference.

Re: Troposcatter & ducting

Yes, tropoducting is almost unheard of in the Southwest. Of course, we don’t get the tropical storms either.

While troposcatter is a useable propagating mode most anywhere and accountable for a good majority of those 300 mile Q's on 10M and above, tropo ducting is another animal altogether and rarely appears in areas of drastically variable terrain like central and western Colorado.
