A friend of mine from my amateur radio club, Yavapai Amateur Radio Club, Prescott, AZ, is one of the ops on the Baker Island DXpedition. He has lots of experience working the CQ World Wide CW Contest with the Voodoo Contest Group in African and Middle Eastern countries. I'm really looking forward to talking to him when he gets back to get feedback on how things were on their end.

I would like to approach this idea with some set of principles that everybody can agree on...so here goes...

#1 Maximize QSO rate
#2 Minimize blind callers

Just those two principles are enough to say we should do whatever we can to reduce blind callers which will also help to maximize QSO rate as they are inversely relates (i.e. fewer blind means > qso rate).

Now...to take the logic to the extreme...if all callers were blind then the QSO rate would be zero...quite obviously an undesirable situation.  As the % of blind callers reduces the QSO rate increases...and the QSO rate is maximized when nobody is blind (notice we're not considering band conditions here as that is not something we can anything about).

So...given the two extremes which should we strive to support?

"good enough" is for horseshoes and hand grenades as the saying goes.  So why would we NOT try to minimize blind callers when it's an easy software change to do so?  This would have no changes on the fox side...only the hounds....

Hi Mike,

we are not hear to determine how operators at a DXpedition site choose to operate, we are not aware of conditions on the ground. If they feel that they are getting optimum rates without calling CQ then that is their choice. Remember that calling CQ from a rare entity can result in a passband 100% full of pile up, they may have tried it and decided it doesn't help the QSO rate.

But what about them receiving all these calls in the blind?  Isn't that going to interfere when they try to respond to people who can't hear them?

OK...so it appears the CQ every 5 trasnmissions is NOT enforced unless Fox clicks the "More CQs" box. We'd be a lot better off if this was always forced and Hounds were restricted to only answer CQ's. This explains why we don't see the CQ's and calling blind is normally necessary (as long as you can see KH7Z that is).

Hi Mike,

it should be reasonable to assume that if the Baker Is. operators are not enforcing regular CQ calls then they have plenty of callers to keep the to-be-worked queue populated with more stations than Tx slots and a QSO rate that is high.
