In my application for an NOV I indicated that erp would be assessed using
the table published by Alan G3NYK and measuring the aerial current. I have
received the following request from OFCOM:
"Thank you for your recent
application for a Special Research Permit to operate in the bands 501 -504kHz.
Your application is currently being processed pending
authorisation.
Whilst this is in
motion I would just like to request
further information.
i)
Could you please
provide a statement on how you propose to control your transmissions to within
the maximum limit of <-10dBW
ii)
Also please provide a
plan view of the aerial system along with complete details of wire lengths and
heights. Also giving relationships to boundary fences, neighbouring buildings
etc
I appreciate that this
was not an explicit requirement in the original application however we do still
need this information."
The site plan is no
problem, just a hassle, though the RSGB guidelines indicated it was not
necessary because of the distance between my aerial and
boundaries/neighbours.
To avoid more delay
any suggestions as to how best to respond? Also as a matter of interest
what sort of figures are current users getting in the way of efficiency,
aerial current and transmitter power output to achieve 100mW erp? I shall
be using a 120 ft end fed wire, 30 ft high on a steeply sloping site surrounded
on three sides by very tall trees over very poor (RF) ground.
