[UK-CONTEST] Domineering VHF Contest Stations

My idea was based on BARTG HF Contests Expert category ( I am the only G 
in that category at the moment), which is based on coming 10th or higher 
in any of the last 3 years. I thought something like this would be 
involve little in the way of administration and would automatically 
adjust itself. I like the idea of calling it a Premier League category. 
At VHF power categories are not as useful as at HF. An excellent VHF 
site running 10 watts will always see some one off running 400 watts 
from a poor site not least because he can hear better than the poor site 
by 20 or more dB.

I tend to use VHF contests to practice my search and pounce technique 
using to two RXs (K3 with transverter) rather than enter them seriously 
as I know from my location I cannot do well even with 400 watts and a 
19ft boom yagi at 65 feet (circa 8KW erp). I virtually never put an 
entry in as it is just not worth the effort.

Different stations at HF (especially in 80m domestic events) are much closer in performance that at VHF. This is in part due to the relative differences in ERP - but also location is MUCH more important at VHF.

As an example of this, both my site, the last two G0KPW sites and the old G4SWX site are all within 50km of each other in essentially flat bits of East Anglia (no obstructions > 5m tall to the sea) and all within 5-15km of the coast. Yet because of the fine details of the terrain the KPW and SWX sites both have been from my estimate 10dB or so advantage (on average) than my site into Germany / OK. However - we are probably about quits into France. It's not always like that - ducts and scatter points move around, but that's an average view built up over many years. That's a big margin to make up - and is reflected in contest results when running similar equipment. Now - these are all decent sites. Anyone away from the flat lands with rising ground in a partcular direction is going to have a far harder time of it still.

Whether you would actually achieve that goal with a change like this is open to debate though since you could easily end up with returning (or new) well sited stations who haven't been classified in the permier league winning each year - is this the route for G4ASR to win ;-) - hey - I'd probably qualify for the basic league having been away for a few years! The entry criteria for the two categories would need very carefully thought through.

Many years ago I offered to have all my VHF single-op entries placed in the multi-operator section - not because I was doing anything which required that - but because I was concerned about the effect that one person constantly at the top of the table could have on the folks below them. In reality in a single band VHF contest - there is little difference in what a competent focussed single operator can achieve in a 24 hour contest to what a multi-operator team can achieve.
