Re: LF: TX-2200A

[Andy Talbot <andy.g4jnt@googlemail.com>]

To quote the data sheet :

 

"The TX-2200A

lets you turn the clock back and explore long waves,

but with technology that the early pioneers could not

even dream of. In a package around the same size as

many transceivers this little gem of engineering will

provide up to 100 Watts of output power."

 

With a CW only option and if it really is a VFO, resulting poor stability  its just an appalingingly ludicrous joke.   And anyone buying such just deserves the contempt they'll get using it.

 

LF was alwatys considered to be the last bastion of real homebrew and experiimentation.

Rant over.

 

But kudos to the manufacturer if they can exploit the gullible :-)    I wonder if its a rip-off of any designs published in the open literature here  There have been quite a few 100 Watt 137 transmitters weblicised - who will be the first to claim his copyright infringements.

 

My 700 Watt Class D Tx    http://www.g4jnt.com/137tx.pdf  probably would cost in the region of £30 - £40 buying most of the components, but without the DDS driver.  Never really priced it as new - everything came from the junkbox.
