Really quick post to put up a link to G7IZU’s real-time European Sporadic E map. Great for those 6m openings!
6m was open to Scandinavia last night and a good opening to Spain this afternoon. Keep your eyes peeled.

As happens every so often, this weekend the Royal Air Force Air Cadets will be organising and running a military style national radio exercise named ‘Exercise Blue Ham’. The Cadets invite all amateur radio operators to take part, making this the biggest radio exercise that the Cadets are involved in.
The exercise will take place on the MOD 5MHz (60 Metre) band and a significant part of the exercise will be on the section of the band that amateurs are authorised to use.
Some important notes if you’re interested:
This exercise does not give amateur stations permission to operate outside of their normal licensing conditions.
– the allocation is not continuous- refer to http://rsgb.org/main/operating/band-plans/hf/5mhz/ for full details if necessary
– the allocation is for full licencees only
– maximum PEP 100W and 200W EIRP
– max antenna height 20m AGL
– secondary allocation, no interference to MoD stations
A summary of suggested spot frequencies in the 60m amateur allocation follows:
Note upper side band, against convention.
Selecting a USB frequency from the list above will ensure compliance and is largely compatible with allocations in other countries. Please do not transmit USB on 5330.5kHz, 5357kHz, or 5360kHz.
Various Cadet stations will be operating on each of the days, mainly from 08:00 to 20:00, but could also be outside these times, and will be on various frequencies within the band. Where possible stations will advertise which frequency they are listening on live on this website as the exercise is in progress and amateurs are welcome to check this page and call in on the advertised frequencies.
Cadet stations will call ‘Alpha Charlie’ which is the equivalent of CQ, and amateur stations are welcome to reply. Exercise Callsigns will all be in the range MRE01 up to MRE98 although other MR, MF and MA prefixed callsigns may be taking part.
The information exchange to score the contact will be
Your Location. 6 Digit Maidenhead. Need not be precise.
As Cadet stations change frequency contacting them again on a different frequency will score as an additional contact, as these frequency changes they will be reported on the exercise website where possible.
The contacts will be plotted almost live on the exercise web server.
The ACO will issue certificates for amateur stations that contact 10 or more Cadet stations during the period of operation using your callsign contact details on QRZ.com. Contact with the same station on different days count as separate contacts. Email your callsign and contact details to claim a PDF Certificate to: [email protected]
The ACO looks forward to operating as many amateurs as they can during the period of the exercise and it will give their young operators an ideal opportunity to utilise their radio operating training on HF equipment to a different audience.
Once a contact is logged into the system it shows up onto a map which can be accessed at http://alphacharlie.org.uk/blueham/showmap.php
Thank you in advance from the Cadets for taking part and giving the operators plenty of ‘Air time’ which cements their radio training that they have received.
A new FM repeater AMSAT satellite AO-91 has just been opened up for general use. Other than it being very popular and thus very busy in the early days, it sounds like it will be particularly easy to work, including from a handheld with a whip.
Uplink: 435.250 +/- Doppler
Tone: 67.0 Hz
John KG4AKV has put a great post up here with all the info.
Programming chart courtesy AMSAT UK:
Memory 1 (AOS) – Transmit 435.240 MHz (67.0 Hz Tone), Receive 145.960 MHz
Memory 2 (Approaching) – Transmit 435.245 MHz (67.0 Hz Tone), Receive 145.960 MHz
Memory 3 (TCA) – Transmit 435.250 MHz (67.0 Hz Tone), Receive 145.960 MHz
Memory 4 (Departing) – Transmit 435.255 MHz (67.0 Hz Tone), Receive 145.960 MHz
Memory 5 (LOS) – Transmit 435.260 MHz (67.0 Hz Tone), Receive 145.960 MHz
Another series of SSTV transmissions from the International Space Station is under way, running throughout this weekend.
Listen out on 145.800 FM. A handheld up to a smartphone’s mic will yield fairly good results.
Passes below – though it’s not expected to be on for every orbit, just select orbits that favour Moscow.
A contact between the International Space Station and youngsters at Gilwell Park, north London, is scheduled for Tuesday 8 August (next week), as part of Youngsters on the Air 2017.
The youngsters will take part in a Q&A session with astronaut Paolo Nespoli, IZØJPA, Flight Engineer of Expedition 52/53, lasting around 10 minutes.
The contact will be at 1838 UTC (that’s 1938 local time) on 2m FM, likely on the standard ARISS frequency of 145.800 MHz, and should be readily receivable using handheld Yagis, turnstiles, or even rubber duck antennas over the UK and northern Europe.
Some more information provided by Southgate ARC here.
Many thanks to the ARISS team for once again coming together to make this event happen – we look forward to seeing the results.
This weekend, ARISS is celebrating its 20th anniversary with a series of SSTV transmissions from the ISS – International Space Station.
Transmissions will be on 145.800 FM in PD 120 or PD180.
Event is scheduled to end at 18:00 UTC on Monday 24 July.
