Useful VHF tropo Indicators

[VK3ZAZ]

Since reactivating VK3RMV-1 I have seen on occasions its worth as an intel gathering device not unlike WSPR.
Patient, unattended and accurate.
And if you don't get on at 700am to hear the morning group the logs are still there for days

vk3rpg WAS GETTING ABOUT 1000 KM ON JUNE 14TH WHEN VK5PJ HAD VK4RTL
The trick is to get someone on air at the precise time, the issue facing WSPR users all the time, how to convert to a qso if that's your aim.

[VK3MEG]

thanks steve i'll have a listen for it testing some antenna's.
cheers

I'm more amused that VK2YGV-5 made it into the list
VK2RNW-1 is the digi of choice in the area. When I plug into it and watch the traffic live it is not unusual to see VK1,2,3 and 4 callsigns flying around and it used to be common to see VK3RPG with one hop and occasionally direct.

VK2RCC-1 was another comparable to RNW, but it went missing in action. The replacement is not as a good position.
It often pays to check all of the local digipeaters to see who they've heard.
