G'day Glenn VK4BG... calling your way now on cw for a couple of minutes....

Wayne.... VK2XN QF59ar.... Narrabri

G'day Glenn, 27 deg to you certainly makes our AE path a challenge with 1000m high mountains 10km out from this qth. BUT I have worked Trevor VK4AFL and Andru VK4KAY via AE in the past month, so with the right plane on the right path at the right time.... it should be possible. :popcorn: I will set ...

G'day Glenn sending a bit of CW your way at the moment on 1296.100 from QF59ar near Narrabri.
VK4RTT 2m beacon up to 579 at the moment.

I see that there has been some activity on SSTV from the ISS. How can I find out when the schedule is to know when to tune in?

Thanks

Does anyone have a Theory on how I received signals like those in the pics below from Mick 2 evenings in a row? Was it at the same time in both evenings, Wayne? And how long was the signal detectable on each occasion? Not every commercial aircraft has ADS-B fitted, even now. (Though we must be gett...

Hi Wayne, Is Mick running true 20W? Has he heard your signal or has it been one way? Hi Leigh, Not sure about his output I'm just going by his report @ 20w. He only hears me on the odd occasion when I use 100w or more. His signal was very stable tonight, around the -23dB mark give or take a dB. A q...

Nice work Mick. VK4NE Airscout speclab.jpg VK4NE WSPR Airscout.jpg Does anyone have a Theory on how I received signals like those in the pics below from Mick 2 evenings in a row? There was no reported Tropo and the flight path has very few aircraft along it at these hours regarding possible AE. Chee...

G'day Barry Thanks for your observations and theories, all credible. The "normal" BNE-ADL route follows the VK2XN-VK4CZ red line to the metre, and doing so would produce very little drift/doppler over the 2 minute WSPR tx period. The one thing I have noticed is the minimal rise and fall of...

G'day Scott,

Beats me how we manage to hear each other at all..

Thanks for the post Kevin, the wheels of progress turn slowly at times.

I'm still wondering if this mode would perform as well if not better than FSK441 on 432MHz.
Maybe the next Major Shower will answer my question.

Cheers

Hello Leigh, My question was prompted by your post re the -28dB decode from VK5AKM. With WSPR-15 having "9dB better sensitivty than the normal 2-minute mode". (quoted from the WSPR-X users guide) I wondered if this had been tested at VHF, 9dB would equal a considerable reduction in tx powe...

Leigh,

2 options.. 2 minute periods or 15 minute periods

Hello Leigh

Have you considered testing WSPR-X on 2 metres?
I know it was developed for LF MF propagation but from what I understand
it is more sensitive than WSPR.

Cheers
Wayne.... VK2XN

Hello Leigh, thanks for the post. Below are a couple of screen captures showing the Northern E's opening on both 6m and 2m WSPR. IPS ionograms for the east coast all indicated a high probability of VHF E layer activity, prompting me to set up 6m and 2m WSPR in tandem this morning. Consistant +11 to ...
