Rick, Conditions were excellent for weak signal testing.
MT63-1000 was not printable by the time the band had started going out. Olivia 16/500 proved to be the best. We tried DominoEX 4 (about the same wpm as Olivia 16/500), but copy was not as good as Olivia. We then tried DominoEX 8 with FEC, and copy still not as good as Olivia. Looks like Olivia is still the best with MFSK16 a close second, but need more tests between Olivia and MFSK16 to be sure. Thanks Tony for sticking with me for some very interesting comparisons! I think the popularity of Olivia is deserved because it does keep printing during deep QSB. 73, Skip KH6TY http://kh6ty.home.comcast.net ----- Original Message ----- From: Rick W To: digitalradio@yahoogroups.com Sent: Friday, March 20, 2009 8:06 PM Subject: Re: [digitalradio] Skip 14106.0 MT63 CQ CQ CQ de kh6ty kh6ty Tony, You have done the tests and found that MT-63 is not very good at handling weak signals compared with other modes. Is you recent on air testing to determine that or some other parameters, such as ability to handle interference, etc.? By the way copying both you near noise level, and Skip, KH6TY, a bit stronger at S3-4. Tried to decode an earlier narrower mode but no luck. Was it MFSK8? 73, Rick, KV9U Tony wrote: > Skip, > > CQ CQ CQ de]kh6ty kh6ty kh6ty > CQ CQ CQ 6e kh6tN kh6ty kh6ty > CQ CQ Cy de(kh6ty kh6ty khX > > Your signal is in the noise.
