But it's a mystery to me why all modes aren't treated in this generous manner, and why other CW operators seem so firmly opposed to the Canadian/European "market forces" model of frequency sharing. Has to do with the compatibility of modes, Hans. Not all mode share bandspace equally well. That's a non-sequiter, Jim. That's why there are bandplans. IARU has been in the bandplanning business mostly everywhere except in the USA for about 75 years. As new modes gain favor (market dynamics change) they reach agreement in their bandplans to accomodate the proportions of users of the various modes. Not all operators follow the bandplans, either. Really? Well then I guess Riley will just have to invoke the "good amateur practice" rule..... oh, never mind, he's already doing that. Not good enough for you..... OK, add a new sentence to §97.101(a) so it reads as follows: (a) In all respects not specifically covered by FCC Rules each amateur station must be operated in accordance with good engineering and good amateur practice. Nonconformance with IARU bandplan guidance is specifically considered a violation of this paragraph. From what I read, the folks in Region 1 are already beginning to notice problems being caused by the "market forces" (loudest signal wins) model of frequency "sharing". A lot of Region 1 hams aren't so happy with how it's working out in real life. "Already"? After 75 years? How many is "a lot"? 50? 50,000? --- One reason for the separation of 'phone and Morse/digital is to maximize the utilization of the available bandwidth. Say you have a band like 80/75 meters. 500 kHz of bandspace. If we allow 2.5 kHz for each SSB QSO and 250 Hz for each CW/digital QSO, (average) it's clear that the band could theoretically support 200 simultaneous SSB QSOs or 2000 simultaneous CW/digital QSOs. Be careful what you wish for. Using that logic, it follows that fair frequency management techniques would allow for an equal number of CW and Phone contacts since the number of regular users is about equal, and CW would lose some man-sized chunks of spectrum. The theoretical "even number" division of this 500kHz band would work out to 90 CW (250 Hz) and 90 SSB (2500 Hz) QSO's. The CW allocation would be 3500-3522.5kHz, and SSB would have the remainder of the band. Sorry, but I can't live with that! Neither should we live with the current plan where CW has a theoretical 2000-QSO band, and SSB is limited to a theoretical limit of just 100 QSO's on that same band. If the number of CW users is roughly equal to the number of SSB users, why does CW now enjoy a 20-1 advantage in effective frequency space (measured in simultaneous QSO's)? 73, de Hans, K0HB |
