Hi Chris,

Watched your youtube clip and I had similar annoying noise. I tracked mine down to be a noisy D-Link router switch in my own home

Hope you get to the cause of yours.

PS-30 still progressing well, last decode at 19:10utc by ZS6AF and ZS4TX. The quality of this foil balloon must be very good.

Slow approach to Namibia

Glad to see that PS-30 is still in flight. I have two receivers listening on 20m and 30m on jt9. Yesterday I set up one of my Dad's rigs at his qth (vk5pp) on 20m as well, 5 element yagi, currently beaming west, short path. Not sure if long path maybe better ?? Good luck PS-30, hope to decode you so...

PS-30 progressing well, currently at +8500m over NZ south Island. Not having much luck receiving any of the telemetry here conditions have not been good. However ZL1RS and VK4RV have been doing a great job receiving and uploading the data.

Hi Ed, I had a time sync problem which started occurring on one of my shack pc’ That particular pc was using gps software to sync the time. Worked perfect for a long time then started problem started. I tried all of the other sync programs (as mentioned above) but no go. What I did discover, which w...

Interesting Andy, we are all enjoying the experimenting

PS-27 may have suffered early battery failure ??? No decodes for a while now

Andy, noticing the jt9 transmission has moved frequency a bit ??

Thanks to your team Mark, it was fun tracking it for a while. Noticed some frequency drift during the flight, not sure if that was due to temperature or Doppler or perhaps both. Received a good signal for most of the flight, lost it at 6500m altitude. Looking forward to the next one :D 73 vk5ei - joe

If using dl-fldigi, just click auto-config and you should be to decode.

Hi Mark, received telemetry from your 2 balloons last week, strong signal and was easily decoded using fldigi. Would be great to send one over to Andy :D On 14th Aug 2014 one of Andy's balloon was 5km from my qth and then did a few circles over s.a. I think it didnt want to go back home :J Look forw...

Should be ok, make sure the coax feed is good quality and short length to radio.

A 70cm Helix design that is being used at Southhampton Uni, England, on their sdr radio is working well. More info at http://g8jnj.webs.com/currentprojects.htm

Hi John, I made several contacts with alan, vk6tdf on the ssb satellite birds and he was using a similar antenna and he was happy about it. What is you plan with this antenna ??

Last decode at 08:10utc, alt 3755, balloon maybe down

thanks andy

Good decodes received on 30m jt-9 now

still getting decodes here, last message

081103 5 -22 0.2 -223 3 * OD5RI RIRI 73

lots more fading now

Getting decodes here as well, signal strength -19dB vfo dial at 145.978

Well done Trash Great to see the kids enjoying the funside of amateur radio.

Great fun Andy, very interesting tracking your balloon payload, still getting wspr reports coming thru on 30m. Might be hanging from a tree branch
Will look out for your next one.

Nice spot Andy, the little transmitter doing well
