Thanks for the overview. Do you plan on reviewing the radio in terms of overall performance? I am on the fence about buying a 6400M until I read more user reviews. A couple of questions, If I may kindly ask: In rx only, does the cooling fan run? Have your tried the synchronous detector on AM signals? (For example, MW broadcast/SW broadcast or AM Hams) Tx so much!
ADKforever I will only be able to say why I picked Flex and other than having to wait so long for the radio it is a good fit for me. Cloud you tell me what you are looking to do in the hobby? Do you like DXing, rag chewing, Digital?
I enjoy shortwave/mediumwave/longwave listening (0-30 MHZ) which include hams, broadcast stations/utilities/maritime/aircraft/beacons. So, knowing this, I ask: In rx only, does the cooling fan run? Or does it only run when you key the transmitter? Have your tried the synchronous detector on AM signals? (For example, MW broadcast/SW broadcast or AM Hams) Thx so much for responding!!!
Q: About the "Synchronous detector on AM signals"? A: I think you are asking about what FLEX calls SAM or Synchronous AM mode. I selected AM and then SAM on a nearby station and then again on a station that was fading in and out. My findings were that SAM did help provide some with the fading conditions. What surprised me the most was how well it worked on a nearby station with no fading. Set at 20K and using my EQ on both types of signals I could hear a notable difference from the standard AM and SAM. In the SAM mode, it almost has a stable High Fidelity quality about it. Q: Does the cooling fan run in receive mode? A: For the most part, I never hear it. With all the other fans in the room, from my amp to my desk top PC, I cannot hear them. But yes, a fan is always moving air. FLEX uses a FPGA (Field Programmable Gate Array) fan. It is a smart fan that gives you both Energy saving and a very quiet operation. This FPGA-based speed controller design allows the fan or fans to change speeds evenly. The only time I have ever heard the fan is when I did my first update. I read in the manual that this happens as a safety precaution. Both of the radio's fans will run at full speed until the update is finished.
