Dave, good point, on the cost, which i hadn't considered, only thinking
of the advantage of more advanced gear, such as receiver selectivity.

I wonder what you mean by tuning difficulty. Do you mean the transmitter
tuneup procedure, which seems a little iffy (but i've not tried it. )

I wouldn't say its a mess. I'd say more like, mid 1930s baroque.
BTW, this occurred to me: since the receiver is practically unusable
for AM reception, due to bandwidth, for CW use you could maybe
re-bias the detector to a product detector and use in that mode. Or,
for AM, build a small converter and use the RU receiver itself only
to tune a range such as 400 - 500 kcs. -Hue Miller
