[TenTec] On Noisy Transmitters

I put little stock in one test at one site by one group of guys on early 
production units.  I know there are loads of 590s in service in contest 
group shacks and have been used happily on many FD sites, so the 
question becomes one of statistical significance.

Rick reports on just TWO (early production) TS-590s at a German contest 
club station.  I know Bob had a similar experience with one or two 590s 
at a US FD site.  But I have NOT been presented with credible reports 
from any other group and this has not been discussed to ANY degree on 
any of the 3 TS-590 web discussion groups - and I moderate one of those 
lists daily.

I do not dispute these stories ... I only wonder whether 4 or 5 reported 
cases is statistically significant.  A great number of 590s are playing 
well among other rigs in a great number of shack world wide without 
problems.  My 590 was nice and quiet and played well with other rigs 
close by.  I cannot get too excited over this until I see more 
(credible) data and (actual) documented cases.  There appears to be far 
more than 12,000 units in service, and this is just not an issue among 
actual owners.
