The Camb-Hams have been activating the Scottish Isles each year since 2008.
As in the past, ten or more operators will be active on all bands and many modes from 4 m to 80 m, 2 m & 70 cm for Satellites and 2 m and 23 cm for EME.
The HF bands will be covered by four simultaneous stations while the 6 m and 4 m stations will have a great take-off towards the UK and Europe. All stations will be able to run at the full UK power limit.
EME operations will use 150W to 55 elements on 23cm and 400W to 17 elements on 2m, primarily on JT65, but also available for CW skeds – if your station is big enough.
Satellite operations on 2 m and 70 cm will use X-Quad antennas and a fully automatic Az/El tracking system. Activity is planned on AO-7 (mode B), FO-29, SO-50, AO-85 & AO-73.
All the up-to-date plans and progress and sked info will be on-line at
Most importantly, this is a group of good friends doing what they enjoy, so please give them a call and enjoy the trip with them.
Active on the major social networks before, during and after the trip, you can check on progress and interact with the operators via their blog or through the Twitter, Facebook and YouTube links below:

Despite the Bank Holiday Essex Skills Night attracted 55 people to the Danbury Village Hall on April 17, 2017. The busy evening consisted of a wide range of activities, among them was 10 GHz SSB by Graham G8HAJ.
He demonstrated how you can start with a simple low-cost 10 GHz receiver using a just a standard Sky satellite LNB (£14:99) and a FUNcube Pro+ SDR or RTL-SDR dongle. This set-up should be capable of receiving the amateur radio transponder on the geostationary satellite Es’Hail 2 that is expected to be launched in early 2018.
The Es’Hail transponder should be receivable on a 60 cm dish with no tracking needed. The downlink will be 10489.550-10489.800 MHz which will equate to 739.550-739.800 MHz on an SDR with the Optima LNB down-converter.
For 10 GHz transmit Graham showed the popular DB6NT transverter and interface board which used an IF of 144 MHz.

The RSGB has published its response to the Ofcom statement on increasing the amount of the 5 GHz band that can be used for WiFi. The Amateur Satellite Service has a Space-to-Earth allocation at 5830-5850 MHz.
Annex 6 of the Ofcom 5 GHz statement says regarding Fixed Satellite Service (FSS) operation in 5725-5850 MHz:
“…once it becomes clear that this band will become used for Wi-Fi worldwide it will become less attractive for new satellites.”
“In Table 2 below we show the impact that different regulatory regimes for Wi-Fi might have on the exceedance of the protection criteria of the most sensitive satellites in 5.8 GHz assuming a comprehensive Wi-Fi roll-out across Europe and Africa.”
“As discussed previously, the risk of interference is an aggregate of all Wi-Fi use and so will rise slowly over a number of years rather than appearing suddenly.”
“The UK cannot cause interference to 5.8 GHz satellites on its own but it is fairly likely that Europe and Africa will follow our lead. This is likely to be driven by the potential for 5.8 GHz to become a worldwide Wi-Fi band.”
