Hi everybody, I see that WSJT has an "ISCAT" mode for ionosphere scatter. I can't find much about how to operate in this mode, or even much about ionosphere scatter in general. I gather that it's a d
Hi Sean, I am no expert by any means but I can share an anecdote or two. I became interested in ionoscatter at 144 MHz after talking to SM2CEW and other Europeans about it. For a period of time in th

On 6M, pretty much any two stations with decent power and at least 5-6 elements at a good height can work out beyond 1000 miles frequently. I think having a good low angle signal is a key to success
Hi Sean, Some years ago while looking for quantitative info on troposcatter for a program that I was writing, I came across a 400+ page compendium on Ionospheric Radio Propagation put out by the Nati

Excuse the ignorance but what mode (software) do you use? From the article/paper it appears MS and IS are very similar in make-up but different natural enhancements to create the path. I've done some
Hi this is interesting. From a practical perspective I'd be curious in knowing if there is much difference in what needed to be successful using long haul tropo scatter versus iono scatter on 50 MHz
WSJT has ISCAT and JT6M that can be used on the mode. It doesn't look like they are in WSJT-X yet. I'm assuming with sufficient power and gain the answer is "whatever mode you want." I'll have to rea
I follow this thread with interest. I make grid expeditions around the Pacific Northwest and am always looking for ways to expand the range when the bands are otherwise closed. There are some rare gr
I've done some MS...great in the winter when you want to heat the shack. Is it similar? At 144 MHz, they are not similar in practice. MS comes in short bursts; IS is there more or less continuously.

There is a considerable amount of path loss, so, in theory, all the "good things" you would want for long-haul troposcatter (or sporadic-E) are useful for ionoscatter. High ERP, low angle take-off an
This has me very intrigued. Do you know of any software that could project an arc 800-1000KM from my QTH? That way, I can look for a station that would theoretically, be in the target area to experim

One can project a circle of given diameter in miles or KM on a Google Earth map. I've done it but can't remember how. Maybe you need to generate a .KMZ file and import it ? ? Keith J Morehouse Managi

After reading thru some of the posted materials and links I'm wondering if the the "JT" and related weak signal digital modes might provide enough of an advantage to make iono scatter viable on 50 MH
