" Hard to fault a Flex except that's it's a bit less than perfect on CW. The new Flex tracking notch is simply amazing. And useful. Does the K3 have that, or the still largely MIA KX3?
The Flex-5000 is test equipment... that can transmit too.
I have had a fair share of Flex operators just wink out on me during a QSO only to hear them reappear 5 minutes later apologizing and cussing about a PC lockup. That's one big fault right there.
I have had a Flex-5000A ever since they first came out and have only had it lock up once while in use. And no, I am not running a high end PC.
The panadapter and incredible filters are worth the rig cost. I worked a lot of DX in the CQ RTTY contest and created a filter that was just slightly wider than a RTTY signal. Having a filter that tight knocks out a LOT of the interference in contests. Also I normally use a 25hz filter for CW. Is there any other rig that has one of those? And BTW there is no ringing at that width.
And now I have I paired with a Elecraft KPA-500 and consider it to be a killer combo.
