Any change in spacing will just change the current/voltage ratio and the phase relationship that the tuner sees, and you'll just end up with a slightly different setting for the knobs. Give it a try - it'll work fine. 73 es gl Bill, W7LZP ------------------------------ Date: 14 Apr 1994 18:43:20 GMT From: ihnp4.ucsd.edu!library.ucla.edu!europa.eng.gtefsd.com!howland.reston.ans.net!math.ohio-state.edu!magnus.acs.ohio-state.edu!csn!col.hp.com!jwc@network.ucsd.edu Subject: High Alt.
