That is an excellent point, and the Mark-V has the same 32V PS problem. I still have the Ten-Tec Corsair for just that situation. As a matter of fact, the Corsair is a better CW rig then the Mark-V. It's only problem is the local AM broadcast station tearing it up on 80m and 40m. As a matter of fact, if I fixed the BC problem, added an Inrad 250hz filter, and did some tweaking to the Corsair, it would be one hell of a CW machine, for minimal additional money. Old classics are a problem for all the radio companies. A TS-850 with a 270Hz filter in the 8.83mhz IF and a 250mHz filter in the 455kHz IF is one hell of a CW machine. I would bet that in 99% of operations, a K3 wouldn't show any advantage. But the TS-850 sure will sound better, most of the time. I'm glad I am short on money, as it makes me think. I may just sell the Corsair, and find an Omni VI, put in narrow CW filters, save some money and get plenty of CW performance. The fact is, I'm cheap.
