Didn't think this one would have decoded from Alan, but it did -

5w to my vertical. I should have a small horizontal yagi running by next weekend if all goes to plan. Interested to see how that performs, particularly towards Adelaide.

I've found my stock TS-2000 seems to be stable enough for decodes at 5w most of the time.

Screen capture of Alan VK3DXE 70 cm signal, doing a double TX stint. Alan's 70cm signal has had a bit a spreading about the signal today, doesn't usually show up like this. There is aircraft reflected signals mixed in across the direct signal, the AE signals dont appear to show any spreading like the direct sig does.

Not sure what was causing the wide signal, but looked weird on the waterfall. At least it decoded, and now back on frequency.

interesting day running about 1/1/2 watts beaming VK5

Have no idea why radio was drifting barely making any power let alone any heat

Steve, drift is most likely AE Doppler. You were pretty weak here most of the day, so it wouldn't take much for a plane to lift your signal.

Leigh, VK2KRR's signal on 70cm this afternoon. Quite a bit of AE, but also a lot of spread on the signal:

Here is a lucky capture of VK4TVL from Townsville on 6m WSPR. Notice that you dont need the full 2 min TX to get a decode. VK4TVL came up out of the noise as pictured.

vk4tvl6mfadein.PNG
VK4TVL 6m WSPR Fade In


Notice prior to this decode there was some powerline noise (next pole along the run), which raised up the noise floor. This stopped just after the 0430 period began. Very low noise level from the 160m Inverted V dipole that I was using. Mostly because its not tuned for 6m of course, but it does work pretty good for 6m sporadic E so it seems (RX only).

Thought it was worthy of posting up. :popcorn:

You can also see Im running 2, 6 and 10m WSPR all at same time here. :shifty:
