Must of missed something here ! UK to W has been done on 100 mW , just takes skill not power ! G .. New updated NOV arrived this morning, no excuse for weak signals anymore on 500 khz Mal/G3KEV
Graham, UK to W has only been done a couple of times under the best of conditions, the new power levels might facilitate more contacts, particularly with U.K. stations who don't live near the coast.
Dear Mal, LF Group, Actually, what I said is backed by hundreds of practical measurements by myself and others. With care, the results are very consistent; I find that field strength measurements are
Dear Mal, Graham, LF Group, This is incorrect. The ERP could be calculated as: P(erp) = (TX power) x (Antenna efficiency) x (Antenna directivity) The directivity of a small vertical antenna over the
Mal...and other NOV holders Please advise when QRV at higher power...will be happy to take a listen from this side of the pond. Jay W1VD WD2XNS WE2XGR/2 New updated NOV arrived this morning, no excus
As a rough guide to get started, assume the average amateur antenna is 1% efficient which is doubtful then you would need 100w fed to the antenna. Since a more realistic efficiency figure might be 0.
That's true , be interesting to see what kind of power level you need to get 1 watt erp from such a large antenna array , looking at the calculators carnt be more than 50 watt's tops , suppose a lift
