Refreshed antenna systems

Following various reports over the last six months of poor performance in some locations on the receive side various site visits were made from 24th August 2020 to 5th September 2020. This has resulted in an updated receive antenna and feeder arrangement. The cavities fitted have also been retuned. Performance is much improved and back to the original coverage that is expected from the site.

Change in settings June 2018

Following some reports of “chopping” on received analogue signals mainly on the edge of the coverage area the squelch settings have been adjusted.  The squelch is set to its most sensitive level and a delay of 1 second with maximum hysteresis has been set. This should reduce the amount of clipping.

As a reminder at this time of the year there are a bank of trees that go into full leaf close to the site and this will reduce access to those to the south and south west of the site.

Tower and Cable Service 12 June 2017

Members of the King’s Lynn Amateur Radio Club worked on servicing the tower and the coaxial cabling on the morning of the 12th June.  The site was tidied up and the tower wound down. The wire cabling on the winch was checked for integrity and serviced.  The coax was also re clipped to the mast and secured to the catenary support.  This will hopefully stop some of the issues encountered during windy weather where there was noticeable crackling on signals where the cable was blowing around.

The matching on the cabling was also checked and both TX and RX aerials  had a good match.

The tower also hosts a standby dual band aerial for Raynet use and this has subsequently been checked and matching is good for 2m and 70 cm.

Updated firmware 22/23 Feb2017

The repeater was off air for just under a  day whilst the Yaesu Repeater unit was returned to the supplier for a firmware update.  This should solve the issue of the through audio being inhibited when the transmission is started whilst the CWID is happening.  The update also allows the squelch hysteresis to be adjusted which should help with receiving weak stations and avoid the rather sudden drop off of signals.
