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: firstname.lastname@example.org
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.
