On site tests of GB3EF

Following reports of noisy audio from weak stations using GB3EF the technical team visited the repeater site and ran a few tests. The noise appears to be generated from the larger broadcast mast adjacent to the repeater mast. When the team switched both notches in line the noise did appear to reduce, however the overall effect of this was at least 3dB of loss to the RX leg. The team are now investigating the use of a good, high quality low pass filter to go between the Aerial and the combiner.
There also appears to be a fair bit of noise around 70MHz which is also where the repeaters RX's image is (51.22 + 21.4 (the IF) = 72.64). The team is also looking at ways to resolve this issue.

New GB3EF on the air

On Sunday 22nd February Jake (G1YFF) installed the new GB3EF 50MHz repeater on site.

First reports appeared satisfactory with the only comments relating to the length of time between the pip tones. This has been rectified this evening by some on site tweaking.

The repeater Logic is of a similar build to that employed on GB3EZ and GB3EA and for this reason is being named the "E"Series logic. The logic is based around the 'PICAXE' pic micro controller with custom software (http://www.rev-ed.co.uk/picaxe/)

Users of the repeater should note that it is essential to wait for at least one of the four pip tones before replying to other users if they wish to prevent timing out the repeater. Failure to wait for the tone will prevent the time out timer resetting.

The current time out period is set at around 4 minutes. If a user should time out the repeater will send 4 pips, mute the talk through audio then send its CW identifier. The repeater will then sit in a loop until the user drops carrier, once this has happened it will send another identifier and be ready for re access.
If a Beacon is heard with PL/CTCSS it means the logic has been reset / the mains has turned on to the repeater.
Don't worry it's not broken, this is how you retune the cavities of a 50MHz amateur repeater!

So thanks to Jake for more of his hard work, please enjoy the repeater and feel free to report back on its coverage in your area.
