Re: Troposcatter & ducting
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

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

Re: Troposcatter & ducting
Last week, there were several -days- of 2 meter propagation between Mississippi and Ontario/Western NY, to the west of Dorian. Eat your heart out.

Troposcatter & ducting
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

Re: DM95
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

Re: DM95
Albuquerque-to-Amarillo: 269 miles. Once you get over the Sandia's, it's a mostly downhill-to-flat path.
Olathe-to-Amarillo: 410 miles.
For reference, My QTH in DM52XT to Santa Fe is 240 miles. Can

I hope we are able to make the contact Arne, and if anyone else needs my grid, please contact me. I am usually available on Slack, ON4KST, NMVHF chat and Ping Central. BTW, I am fairly new to 6M and

Re: DM95
I would think that FT4 would be better than FT8 with respect to meteor scatter. The time interval is half, so the odds of a meteor ping are halved too I think.

Steve - I think he is talking between Amarillo and Olathe. That is pretty long for Troposcatter.

Re: DM95
Arne,
I saw you calling him yesterday on FT8 but never did get a decode from him. I did get a couple decodes today on MSK144 of him calling you.

Re: DM95
FT8 officially sucks as a mode when there is meteor scatter mixed in. Just a single big ping of scatter within FT8's 15 sec receive window will likely prevent a decode on a weak signal.
I suspect FT4

Re: DM95
No just shorter requirement for a exchange. A short ping on FT8 is useless but a contact can be made with msk with nothing but short pings. Takes a lot of time however

Why ? Are you saying that the only mechanism that could support a QSO is meteor scatter ?

MSK 144 would work better for that distance with no other propagation to help. Just MHO
