Yes.......properly adjusted phasing type SSB generators have always been
known for their excellent audio ala HT-37, 100V and now, even though it's
performed in software, the KX3.
Maybe that "chirp" could be a new feature for Wayne to incorporate so we can
pretend * we're operating a 30's hollow state xmtr.

Ah yes, the "Scratchy Apache" was a fine radio. I had the SB-10 SSB
adapter to go with it. It worked great with a VHF transmitting converter
because the low-level output from the SB-10 was just about the right power
level to drive the converter.
I used to frequently get unsolicited compliments on my audio quality. (No
crystal filters in the transmit path.)

the TX1 with High level plate modulation it will do way more on AM than
the K3 I get about 110W carrier. the TX1 didn't do SSB without
additional hardware which I have but its not yet restored. the real
point is the vintage fun factor of restoring and getting on the air with
110lbs of iron.

Re: Heath TX1 power --
The Heath TX1 used a pair of 6146 output tubes, those normally run 180
watts *input* power.
Modern transceivers (K3 included) are rated fort power output.
If one assumes a 67% efficiency (realistic) at 180 watts input, the
output power will be 120 watts - that is about what one can get from a
K3, although I do not recommend running the power knob to more than 100
watts to keep IMD under control.
Sooo - I don't think the TX1 will "crank out a whole more power" It
seems to me to be about the same.

Good question and answers here I did the same as don suggested up
till recently. I have a Heathkit TX1. I had no receiver until
recently when I got the RX1 to go with it. bit of a crappy reciever
but its still a fun to do the nostalgia thing. The TX1 will crank
out a whole lot more power on AM and CW than the K3 and it warms the
shack in the winter. Its not all DX and contests sometimes its fun to
get out the old and tinker. next up is 1930 era two tube push pull
UX-245 40m transmitter now were talking chirp!.
