[Lowfer] Can I expect to receive ....

[WD8ARZ]

That article would be great Doug, appreciate it.

Got to dig into my box of matcher ... I might have a one I bought 
decades ago for below 500 khz ... can always modify one of them if need 
be. Have a long coil stock here that hasn't been cut into yet ... hi

Ok, will search out Argo and test it out this week. Thanks for the 
feedback Doug.
