Terra Tranceiver : new composite antenna with metal ground plane.
Yesterday (dry, vis 5km, light southerly), I tried the new composite
aerial
arrangement for the third time. (From 1700ft agl)
Here are the complete results for the session:
Station Contacted Readability Distance of station (Nm)
Stapleford 4/5 10
(at one point, reported 'not very good')
Clacton N/N? 23
(only aircraft xmit heard at any time)
Andrewsfield 4/5 4
Elstree N/4 26
(reported 'unreadable')
Earls Colne 5/5 7
(responded on 2nd attempt)
North Weald 5/5 17
Biggin Hill 4/5 37
Southend 5/5 17
NB.
Readability scored as Xmit/Receive.
N means no communication.
These results seem fairly good to me, and are about the same as last
week. The Stapleford
comment disturbed me, as did the lack of response from Clacton. On the
other
hand the result from Biggin is encouraging. Hopefully, poorer weather
will not attenuate the
signal. I would hope to talk to easily to 9 out of 10 stations within 20
Nm. Is that a good
bating average, or not ?

On a completely separate issue, I now have a mouse living in the foam
core
of my tail-fin (I can hear it scratching periodically and have seen the
tell-tale
signs of shreaded foam and mouse droppings). Any suggestions in
addition
to the obvious (poison for them to eat, mouse-trap and ultrasonic
emitter),
gratefully received ?
PS. They haven't gone for the uphostery yet, they seem to love the foam.
(apparently green wiring is also vulnerable)
