I spent some time in EN24 yesterday with some folks from the W0CRC (
Crow River Radio Club). Chris KC0YBM was putting on a demo showing folks how to work satellites to make some QSOs. He has a nice portable setup where he can operate from the back of his Subaru with an FT-8800R and an
Arrow antenna.
I spent the afternoon shooting video and stills to put together a future presentation for a couple of the local clubs. As part of that activity I concluded that I should be able to make a couple of quick changes to my shack that would allow my me do the same thing from home.
So today (Sunday) in between the normal chores I managed to put a couple of new QSOs in my log.
It looks like I have a DST error in the log... should be 23:xx.. fixed.
AJ5C was my first QSO via satellite. K8YSE was my second. Both of the Q's were completed on the AO-51 satellite.
Here is a quick picture of my temporary shack from my camera phone.
I am running Linux with the program
GPredict to figure out when the satellites will pass my area. I am running
CQRLog as my standard logging program. Nothing too fancy here, it is your basic HF+VHF/UHF/Microwave+QRP shack.
(My Elecraft K2 is not in the picture as I am doing some work on it over at the work bench)I used a FT-1900 (2m FM) as the uplink radio connected to my 144mhz SSB/CW weak signal antenna. I used a FT-7800 (deaf on 2m but 70cm FM works fine) as the downlink radio connected to my 432mhz SSB/CW weak signal antenna. Both beams are on my VHF tower.
The antennas are not really tuned for this high in the band but they seemed to play ok.Since AO-51 is a FM bird you dial in the uplink frequncy 145.920mhz and just leave it alone. I then dialed in the downlink frequency of 435.300mhz. I then swung the antennas to the southwest and waited. AO-51 rose in the southwest and then made an arc to my northwest and was pretty easy to follow. I had some slight doppler shift on the downlink so I ended up tuning in at 435.305mhz.
QSO with AJ5CQSO with K8YSEThe QSOs can be pretty short as there are a lot of folks trying to work people in a very short window. Typically it is callsigns + grids + roger/73. There are is some occasional chit-chit if there is time and it is not too crowded.
Sure, a nice dual-band/two-band-at-a-time rig like an FT-8800R would make this easier. This took about an hour to setup to make my first QSOs via satellite and cost nothing.
I will likely get a satellite friendly radio and an
arrow antenna for portable operation while on photo trips, camping, and family outings. This was pretty fun. At some point I would like to try to work some of the linear transponders on SSB and CW. --That is an adventure for another day.
