QO-100 Satellite

Now for something completely different – 13cm/3cm Satellite!

A21EME announced that they would be on QO-100 and so on a wet Sunday afternoon in October 2019, having already worked them on 2m and 6m, I decided to have a go at a junk-box QO-100 setup in the workshop: SG labs 13cm transverter, wi-fi 5w PA, 31el long yagi on TX. 80cm sat dish, unmodified LNB and RTL dongle on RX. Result - A21EME in the log.

I’m a Life Member of AMSAT NA but have not been active since the early 1980s (as H44PT on AO-10) so this is really fun.

March 2020 - my updated QO-100 setup is now operational:
IC-9700 TX on 432MHz into SG Labs 13cm transverter and SG Labs 20w PA feeding 1.2m offset dish via home brew patch feed (POTY).
IC-9700 RX on 144MHz from modified LNB with DX Patrol down converter and GPSDO locked.
With the IC-9700 in satellite mode this gives me full duplex transceive.
Can also RX with SDR Console or the Goonhilly websdr on my workshop PC (all options covered!:-)

I have adjusted my TX power to make my SSB signal about 2-3dB weaker than the beacon but at this level I sometimes trigger the LEILA alarm if I use CW. I only need about 3w at the dish so I run the system well backed off – so much so that I need to add another attenuator as the IC-9700 is already on minimum output.

29/7/2021 SPECIAL UPDATE The secret is out. NA continent is now on QO-100 satellite!! A couple of months ago I asked Bo OX3LX if he was interested in trying QO-100 - just above the horizon in SE Greenland. Many thanks to the “Thee Musketeers” PE1CMO, PA2V and PA3FYM for supplying the flyaway kit and to Bo Christensen OX3LX for finding a suitable location in Greenland. Surprised and delighted to get the first ever QO-100 QSO with “NA” Continent on 29/7/2021 after txt from Bo for test. CLICK TO HEAR THE TEST

My QSO(s) with Bo meant that I had Worked All Continents on QO-100 - and here is the certificate to prove it:-)

December 2021
5th ACTIVATED IN79 Bass Point on the Lizard in Cornwall for the first time on QO-100 A historic site between the Lloyds Signal Tower and the Marconi Huts GB4LD -  flags to sparks to satellites!! TNX to all for keeping me busy - 151 QSOs in 36 DXCCs. Beautiful sunny day but a bit cool with wind gusting to 50MPH+. Lots of rocks required to hold 1.2m dish stable:-)

23rd April 2022 INTERNATIONAL MARCONI DAY at the Marconi Lizard Wireless Station Bass Point  Using GB4LD IN79jx
Good interest from visitors and some nice results results on the QO-100 Satellite.
Total Contacts with other Amateurs "QSOs" 161
Total Countries contacted "DXCC" 34
The GB4LD “message” was exchanged far and wide via QO-100! - From Svalbard to South Africa and from Indonesia to Brazil
It would have been great to contact the hams on the German Antarctic Research Station for an Arctic / Antarctic double ! Unfortunately they had work to do so couldn't play ham radio.
