Well my guess that most hams have the tuner at the radio (or inside
the radio).
I was trying to minimize my cost when I bought my K3/10 (only $2900
with accessories), so I did not buy the 100w amp or atu. I already
had a used MFJ mobile tuner (good to 200w) so that sufficed. The MFJ
finally died (not worth fixing) so I bought a used Drake MN2000
manual tuner. It handled my CCI 300w amp (and gave a handy RF meter
to show output). It is in the shack (arms not long enough to reach
the knobs on top of my tower at 50-feet).
I only have two operating HF antenna: 80-40m fan inverted-V and
Hygain TH3mk4 triband yagi. 80m matches where I operate (75m phone)
and 40m needs a bit of tuner with 3:1 SWR. The old tribander needs
a bit on all bands. Tuner only use is to make the ssa happy with
providing a 50-ohm load. Feedlines are about 80-foot.
I have one more wire antenna which is used on 600m: 43x122 foot
inverted-L. I has a huge base coil for matching. SWR bw is about
5-KHz (495-500 KHz) and efficiency is < 1%. But my 4w ERP has been
received in Buffalo, NY; not too shabby. Feedline SWR runs about 1.5
for the 100w amp.
My first transmitter was the DX35 with 6146 and pi-net output
tank. Peak n Dip could load anything. SWR? whas dat? I did not
have a power meter. FCC regs told me I could run 75w dc input.
