Until, possibly, now.
K1N should be starting up very soon. Navassa Island is nestled comfortably in territory that I have always reliably communicated with. But this little spit of land is so high on the DX wish list, that it rivals North Korea on some DX'ers most wanted list.
I expect nothing less than pandemonium in the near future. Expect mile wide pileups on the HF bands as everybody and their uncle try to work this DXpedition. So, while 5 Watts has never failed me up to now, I haven't decided my approach to K1N, yet. If I decide to jump into the fray very early, it will be with 100 Watts. However, I may also wait for the second half of the expedition, when a 5 Watt attempt may be more doable.
UPDATE: K1N is on the air! I am listening to them on 40 Meters on 7.023 MHz, Currently the pileup is going past 7.035 MHz. I think there might be an issue for the 40 Meter QRP Fox hunt Tuesday night.
