Hi Ray, I live very close to you and have no problems with VK3RED reception here, i have a larger problem with the 1K eirp from the the nearby Paging Transmitters. Please come up on the Local UHF repeater VK3RGU 438.375 mHZ after 8.30 PM to discuss with the beacon custodian. Or come around and we ca...

Thanks, Bob.

Thanks for the information.

Hi Peter,
Will look for you on the logger over the next few nights.
There are few stations here in gippsland with JT9 installed as part of wspr-x, was testing with norm vk3dut a few nights ago.

jim, VK3ZYC.

Hi,
Perhaps JT9 is a possibility, seems to work ok on the balloon tracking out to several 1000 km on hf with lighting crashes
Willing to try with you anytime, can run it just below the wspr freq on 2m with 1000 Hz mod freq.

see topic WSJT-X
may be of some help.

hi, Now have several decodes. 0703 -6 -0.3 997 @ 1/VC25GP5209X 0802 2 -0.0 994 @ VK3YT19B36RW0 1002 3 0.3 995 @ VK3YT19836Q80 1003 3 0.0 995 @ 1/S-26QQ4/ZC4 1103 -1 -0.0 995 @ 1/SM27334/M76 dont always get both packets, possibly due to other signals in the passband. Rx here is GPS locked to 10.36870...

Hi All,

Can anyone listening to the JT9 signal on 10 MHz advise the current frequency offset it is transmitting on.

I can see the WSPR signal but have no decodes of the JT9 signal. I am looking 1000 Hz but no decodes as yet?

Hi,

I had a problem at xmas with a new noise source wiping out 2m band, pulsed at a 2 second rate. Only on at night.

Traced it to a set of solar powered blue LED lights i had put up outside as decorations. a Very nice noise generator.

Hi,
Have a talk to Premier Batteries in sydney (you will have to look up the phone number)

They have supplied gates cells to our firm in the past. These were for IFR500,s they may even make up the pack for you.

Hi,
Only seen 1 report of signals rxed, and a report that the mode J transponder did not fly also.

Should be able to pick up signals with single 9 el yagi and using spectran or wsjt to look at signals
will be too low in s/n ratio to hear most likely.
