[Elecraft] K4 transverters

[ray2.s at btinternet.com]

I have had a look here but can find no mention of any Elecraft Transverters
for the K4 radios since 2021. 

Do I take it there is no timescale for their release from Elecraft or is it
that Elecraft will not be producing any transverters and now expect us to
use 3rd party transverters?
