I will rub along with a majority view.

 

My statement about the number of NoVs issued was a lie, I am ashamed to say.

 

However Geri got the reference.

42 is the incomprehensible answer to the ultimate question of Life, The Universe and Everything which is less incomprehensible than current NoV for 630m (472/9kc/s). Another answer to the Binary string 0101010 or the answer to twice the "key of the door" but we still need a question.

 

Since Geri was on his way the Restaurant at the edge of the Universe after no doubt downing 6 pints of best bitter or in Geri's case 3.40957Litres of best Holstein Lager to avoid the impending approach of the Vogon destructor fleet to build a hyperspace bypass through Earth starting in the mountains of France; I thought that he may enjoy pondering this conundrum. However its all to no avail since the fleet has obviously been withdrawn. Not like the impending destructor fleet heading to the M25 in Kent.

Pete, I think the main requirement band plan wise is knowing which section to monitor for QRSS and other narrow modes, as one is restricted to quite a narrow bandwidth, very narrow with the slower QRSS, of course.

Incidentally, how did you know 42 NoVs had been issued for the new band? I cannot find this info on the RSGB website, but not sure where to look....

Hi Chris

 

Just seen the dreaded words "Band Plan" I think there are some who would not like this, me included. The Band plan is the RSGB Police-mans weapon of choice. Four meters has gone from a friendly rub along band to a band with abusive RSGB Band Plan individuals that are never heard in QSO's but come out of the wood-work and jam the channel in the name of the Band Plans.

 

So nailing my colours firmly to the mast I say no band plan (well not written in stone anyway). I have even had unsolicited e-mails from Amateurs purporting to be RSGB officials who ought to know better. If OFCOM decree some form of plan like avoiding NDBs and the like well OK but they are the only authority that I am prepared to obey apart from a common sense avoidance of deliberate interference something lost on the channel jammers on VHF!

Hi Pete and Geri,

Codec2 might be a viable medium term solution for real-time compression
of speech for narrow band communication (http://codec2.org/).

There is also an interesting presentation about Codec2 by David Rowe on
youtube: http://www.youtube.com/watch?v=KsywWf8dQgU
