It Baffles me on why you have created this topic as you claim you have a 3 year Well Established Station.
If your station is that good I cant really see why your topic will get you revenue from other stations which could be potentially classed as a Rival Station.
If your station is not making any money then you do have options to consider.
1, Bite the Bullet and continue running at a loss but still have the pleasure knowing that you do provide a service for the Minority Listeners (Like a lot of stations do)
2, Cut One's Losses and Accept Defeat and join another station.
I personally don't think it is feasible to run your own station and expect other stations to fund yours in the process.
If you do get a station (Rocking Horse S**T Springs to Mind) to fund your station when they need revenue for their own station to continue to run then good luck.
Loads have tried to piggyback other stations for gain with no success because we all have bills to pay every month
