Yeah very expensive and another SDR radio with a junk transmitter with poor IMD performance.
Regardless of the ham transmitter manufacturer, its the same old same old lousy TX performance.
Its is very easy too design and build a SDR transmitter that produces very little splatter or IMD. Its also very easy too design a low power PA that is clean.
But this is typical what QRP companies do, they build the worlds worst PA in their QRP transmitters.
If they took leaf out of military radio producers and copied what they did they would get some respect for being innovative. Most of the low military transmitters run class A and they are very clean.
Once you have a clean QRP driver it then becomes a good foundation for either building a super clean tube or FET PA.
The 1 st law of ham radio physics is that excellent receiver performance is wasted when you have substandard transmitter performances. Unfortunately all ham transmitters are sub standard.
The fools are the hams who continue on the road of enlightenment demanding better receiver performance and say nothing about the poor transmitter performance. Idiocy at its best I am sorry too say.
A lot of hams dont get the joke that is being played on them by all the receiver number propagandist. While the objective of the argument was a legitimate one a decade ago, the argument holds no weight now
while manufacturers are still selling radios with poor keying sidebands and IMD. Even worst is the terrible ALC designs that by their nature cause excessive splatter. Who is listening ? Unfortunately nobody because hams dont understand the issues all that well and just say nothing and continue to buy the crap.
Expensive for a QRP rig also.
