2820 ICF file for download
The South Yorkshire Repeater Group now has for download via the Charity Shop an icf file for the 2820.
Included are all the UK VHF/2m and UHF/70cms repeaters in alphabetical order, followed by the same format for UK Digital Nodes. Obviously being based in God’s home county and biased towards GB7YD there are memories options to link GB7YD to any of the currently available reflectors.
We hope that everyone enjoys this usefull file for when mobile with a 2820.
The file is free for download and available to all, many thanks to Ian – M6DER for taking the time out to put this one together.

D-STAR SIMPLEX EXPERIMENT
Saturday the 10th of July 2010 I shall be running tests on the DV VHF simplex frequency 144.6125Mz from 10:00 through till 18.00 hrs GMT
The aims of the tests are simple. I would like to establish some statistics on D-Star VHF simplex for comparison with standard FM.
I have already tested it over a short distance and found the audio and signal quality was 100% better. Tests indicate that the simplex mode of DV compared to analogue simplex modes is superior, but I would like to gain more facts. This will require more users to make contact on the day with reports on their location, power and antenna used and if possible a comparison on analogue using the same setup?
To do this I need people who can be on the radio at the same time as me, this could be a very interesting experiment and I am willing to publish those statistics on the South Yorkshire repeater group and my own rotherhamamatuerradio websites for all to make use of.
What we need is;
- for you to register your interest
- to be available on the 10/07/10 form 10:00 till 18.00
- to be able to keep a log
- send your log in (via email)
Anyone wishing to participate please contact Ian M6DER to register your interest.
Later this year I shall be doing some tests using D-Star TV also, anyone wishing to take part in this should contact me as well stating dvtv in the email.
Thanks for your time.
