Not a good wager.

?  Not according to N7WS' measurements.  Nichrome has over 50x the 
resistance of copper.  Add R and ''actually have higher Q''?  Behold, the 
world according to Tom.

? People have replaced crispied-crittered bandswitches in AL-80s, AL-82s, 
TL-922s, on and on, only to find that the new bandswitch also 
occasionally arcs.
