KX2: Sub 100mw power setting?

[Elecraft mailing list]

Would it be possible to configure the KX2 through a firmware update to transmit at power levels below the 100mw low limit? If the PA is capable of being stepped down that low I'm interested in experimenting with very low power transmissions and it would be convenient if I could access levels somewhere in the range of 50mw to 5mw without the need for an external attenuator. 
Thanks!

Hello,

I second that! Beeing a 5 Watt Operator for nearly 20 years, I discovered
in the last years the Joy of qrpp down to 0.5 mW . And I can tell you it
works. So I consider 100 mW in CW nearly QRO. In Wspr 200 mW is definitly
Qro and I tx most of the time with 10 mW with the help of a step attenuator.

So the control of the power level from the Kx2 down to 1 mW would be a
major improvement.

It is pretty easy to find inexpensive attenuators to step QRP power levels
down to QRPp levels, including at least one I ran across that switches out
of line in receive mode. Just a thought!

at QRP levels, you can easily make a relay bypass,  the relays used in the
2m DG8 pre-amp will suffice..

Maybe a little over-engineered... those relays will handle 1kW!
