Hi, Barry.  I have a Ten Tec 340, as well as a HF-2050, an Icom 
756ProII,  a R390A with a SE-3, and a AOR 7030+ which are often on at the 
same time, so A-B-C-D-E testing is possible.  Of all these receivers, (and 
this is only my opinion), the Ten Tec performs the worst on MW with a 
strong adjacent signal.  The MW dxers out there are well aware of this fact 
and have gone to some trouble installing roofing filters to correct the 
poor performance.  For the longest time, I A-B'd the 2050 and the 340 and 
virtually in every instance, the 25 year old 2050 out gunned the 340 by a 
long shot.  I was all set to sell the 340, but it's performance on HF is 
really very good, and with ERGO4 computer control, it's a very nice set 
up.  The 7030+ is an excellent performer in close, as is the 756, and of 
course nothing seems to bother the old Collins R390A.  I know several of my 
MW colleagues have added the roofing filter on the 340 which improves the 
performance markedly, and they seem very pleased, but at the price of 
losing the wide audio bandwidths available in the 340..........Walt.
