The idea is that they want to calibrate the 10 meter receiver on the Juno spacecraft, which is heading towards Jupiter.  NASA wants hams to send "HI" (..../..) in very, very, *VERY* slow Morse (like, 1/125th of a word per minute slow).

I wish that I would have known earlier, I'd dig out my 10 meter transceiver. Might do it anyway if I can find my code key.

I'm doing it right now.

I'm only pushing out about 60 watts because I don't want to overly stress my finals.

Right now, we're in the 240 second "quiet period".

My rig is hooked up to my computer as a remote base. I'd have to pull a lot of wires to run CW. I do have a 10 meter 25 watt rig. Since I have two hours I may just power it up later. I'll post the link to my google+ ham group also. Thanks for the post. I'm surprised that I didn't hear of this earlier. I haven't logged on to QRZ today yet.

I may only key up for 10 seconds, the radio is 30 years old.

I only heard about it because I was "reading the mail" on 20 Meter PSK.

So is mine.  TS520.

Actually older than that, I think:  It's from the 1970's so more like 40 years old.

PSK is on my list of things to do. I'll build a TNC with a Raspberry Pi.

My bench is full of preamps and rf switches that I'm building for 2 meter SSB weak signal right now.

All I have is a cable that goes from the headphone jack of the radio, to the mic jack of the computer.  When I want to transmit, which is rare enough for digital modes, I put the radio into vox, and put the computer speaker up to the radio mic.  Works great.  Doesn't take a lot of effort to do something like that, just has to be a quiet room.

Fooled around a bit with JT65 and JT9 also, and Hellschreiber, which is a neat mode.

That would work but my house is seldom quiet. Noisy dogs and a talkative wife. ;-)

Unfortunately for Juno, 10 meter propagation was very good for the first time in months yesterday at this time.

Also, I run a ham radio trivia net every Wednesday night at 5 pm PT. Echolink *world* conference server node 479886, IRLP reflector 9251 and Allstar node 27626.

Join us if you can. Its nerdy ham fun.

Oh, I know it was good:  I snagged HC2SL and LU7HF via CW on my drive home yesterday on 10 meters.

Still, worth a shot.

Currently in QSO with US5CCO in the Ukraine on 20 meters, using JT9.

what's Morse code for, "Jane, stop this crazy thing!"

Ditty, how was Juno s'posed to respond to your signal?

Did she?

Or did you run afoul of her going into safe mode?
 
2013-10-10 02:35:02 AM  
Oh, I see. The results are upcoming.

Kittypie070: Oh, I see. The results are upcoming.


Juno wasn't going to be able to distinguish any one single signal, because the receiver bandwidth is too wide:  It's designed to collect noise at Jupiter, not discrete signals from Earth.  The idea was, with enough people transmitting the same thing at the same time, spread out within the receiver bandwidth, that it would be detectable on a close fly-by.

I don't know what the results are yet, but I did e-mail them my information for a QSL card.

w00t!!

thanks, ditty :D
