This was a short SOTA outing on 2.3GHz in the somewhat vain hope (given the conditions) of contacts to the north. However I was hopeful that I would get at least one contact – which is what happened.
Great talk yesterday evening from Brian Flynn GM8BJF on the use of Chinese PLL boards using ADF devices.
Welcome to GM8OTI’s blog website. Here will be all things amateur radio related …
This has just arrived from China – part of my intention to do a bit more amateur radio this next year. I’ll be using your instructions Jon 😉
This is the 70cm (435MHz) omnidirectional antenna for satellites I have just finished – called the “eggbeater” for obvious reasons. It also appears to work well – this afternoon I heard HO-68 telemetry, and FO-29 twice – once on a low pass to the north, then again on a much higher pass, during which I clearly heard Italian (IW3RGK) and German (DL5OCD) amateur stations calling through the satellite. This is very satisfactory for an omnidirectional antenna, especially as I find the receiver in the FT-817 radio is as deaf as a post on 70cm. I shall make a little preamplifier for it before I try any satellite contacts.
I’ve made a new omnidirectional satellite antenna for 2m – a turnstile. Set it up on the balcony this morning (ignore the washing line ) and heard three satellites on 2m – the International Space Station, FUNcube-1 and UKube-1. Also heard HO-68 as a weak signal on 70cm. The next step is to make a 70cm omni antenna so I can hear the UHF signals better, and transmit through the FUNcube satellites.
For my satellite tracking buddies – I’ve just come across Gpredict http://gpredict.oz9aec.net/index.php which is something I’ve been looking for – Linux software that will drive an antenna mount to track the satellite. It looks very good indeed. Apparently there’s a Windoze version too …
