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.

Thanks for the comparisons Walt. I was thinking strongly at one time to buy 
an RX-340 but after reading recent posts and comments about it I'm not so sure 
I would like it since I do a lot of AM BCBand Dxing. From what I have read so 
far it has a steep rolloff in the audio response which makes using filter 
choices wider than about 8 KHz or so meaningless and apparently poor strong 
adjacent-signal handling ability in the BC band. Adding a roofing filter would just 
about guarantee losing wide audio bandwidths for AM. None of these 
shortcomings were mentioned in the early reviews of the RX-340. I am still in awe of the 
ability of the HF-2050 to pull good-sounding audio out of an extremely weak 
carrier in AM mode plus its superb performance on LF and the medium-wave BC 
band. 73 Todd Roberts
