Yeah its a real shame ham companies dont pay much attention the RX audio chain. 1 watt audio amplifiers with 30% distortion is the norm. Then they pay no attention to the
inband audio IMD ,and reducing all IMD products from the RX chain. Most of this IMD comes about because of poor parts selection and generally poor engineering.
The K3 is another radio in point that is very fatiguing and noisy despite its upgrades. I had a listen to a Flex6000 and it does have a very pure clean low noise
audio chain. They just ruined it by using a poor audio amplifier. 5 watt and 10 watt class A audio amp modules are readily available so why use a 1 watt mickey mouse toy
amplifier in such an expensive radio. I mean high power low distortion cheap amplifier modules would probably only would have cost 1 dollar extra.
The Flex6000 would have been a leading edge nice package if they packaged some good engineering into the box. However the compulsion to take the cheap, nasty and poor engineering road is quickly becoming apparent. The Flex6000 could have been a benchmark world class product but now looks like it will have all the failings of the typical amateur products already on the market.
What gets me is that there are so many individuals hams who know about these products and their faults, They also know what hams really want. Yet at the same time the companies fail so miserably at doing their market research. Why are such glaringly obviously faults and features forgotten about if they in business wanting to make money? I sometimes just get the impression that many of the CEO's of these ham companies are very arrogant engineering types who think they know everything yet fail to get even the very basics right. Very disappointing.
I am sure many hams would take the time and do market focused surveys if they were asked. I dont recall any ham transceiver company ever asking their customers what they really wanted. Thus just shows how out of touch they are with modern marketing principles and their willingness to understand their customers wants and needs
I am glad its not my money invested in these companies.
The Flex radios are easy to listen to for long periods due to lack of distortion, good AGC, and especially since your can adjust the AGC threshold easily with a slider. This has a lot to do with PowerSDR. IMO, the KX3 is NOT easy to listen to for long periods. There is audio distortion unless you use headphones on an external speaker amp and it become tiring after a while. The receive audio is too harsh and processed sounding for my tastes.
