Just been delving into the innards of the Argosy I which I got second-hand
30 years
ago this month; the dial cord has stretched again and needs to be replaced.

Here is eqpt using regular non-specialist components that is maintainable by
any _REAL_
radio amateur, unlike a lot of modern rigs that are so densely packed with
miniaturised special-purpose ICs that maintenance or enhancement is almost
beyond the capabilities of anyone working on the kitchen table.

For the good of amateur radio in general, would we be better off living in
the
past with the state of the art of 30 years ago, so that all licensees would
have
the capability to continue to maintain for themselves their equipment, and,
by having that capability, perhaps be motivated to continue the grand
tradition
of homebrewing their rigs?

GRRRR!!!!!!

With the exception of the dial mechanism which has a cord pulling from one
end, with
a stretchy bit of nylon to pull the LED pointer back. Works fine until the
stretchy nylon
exceeds its elastic limit and then the dial no longer returns to the zero
position.

Luckily, I have a lifetime's supply of the stretchy nylon!

Are you using proper dial cord. The cord should be non stretch,
tension is usually maintained by a spring. ISTR its quite hard to
come by, the cord I have now came from a small shop in the
states.
The vintage radio forums may be of some help.

I don't know what may be available across the pond, but here in the
States I would go to a store and buy braided nylon fishing line.
(Definitely not monofilament line!) That has worked for me for years, in
fact since I have not been fishing in decades I just work off of a spool
still mounted to an old fishing rod. Braided line is built not to
stretch much, and is available in different strengths.

Actually there are two cords; one is stretchy and causes the problem.
T'other is not.
T'other pulls the LED pointer across the scale from one end, and when you
tune back, the stretchy bit pulls it back!
