Hmm, I did not think of braid. You could also solder the two ends together.
Just may be something to play with.
I am pretty excited about this old rig.

I would avoid soldering it, except at the very end to keep it from coming unbraded.
AF6LJ:
Just finished putting the attenuator switch back together, took two attempts to get it right.
This is one time where following the HP assembly instructions were not the easy way to get the job done.
Allergies today, I have a splitting headache, pictures tomorrow.
Stay tuned.
AF6LJ:
I was rather far along on completing the assembly of the front panel manual when I discovered the frequency span switch was two positions short.
So from this point....
I get to remove a few parts and re align the frequency span switch rotor with the detent.
It's not really a big deal, but it does involve some work.
Fixing it shouldn't be a big problem, we shall see.
Stay tuned.
AF6LJ:
Oh and before I forget...
I will be doing a somewhat in depth teardown...
I need to do a good inspection and make sure there are no floating washers or switch contacts in the unit that could not be shaken out.
Radio Tech:
Will be waiting on the next task Sue.
I know what you mean about a good tear down inspection. So many things could be in there waiting to ruin your day!
