Subject: Re: [TowerTalk] Uses of MFJ 259B
The MFJ 259 has measures many functions.
It measures just about all transmission line equation parameters and the
alterations caused by loads - antennas.
Here's its parameter list and how to move to them.
## here's what it won't do.
## it's a dead loss when measuring inductance and Capacitance. I Tried using
it to make tank coils for
hb linears, and it's out to lunch, not even close. 3 x mfj's were tried.
## I use a B+K 875-B for accurate L + C measurements. Then everything is
dead on per the spread sheet.
## They warn you not to inject a signal into it, for freq counter purposes, if
unit is not powered up. You will damage the unit.
## The optional grid dip coils won't dip anything, even a simple parallel
resonant circuit. Several friends also
commented they too, couldn't grid dip anything. Even W8JI says they don't
work. I use a real GDO.
## everything else seems to work fairly well on the 259.
