It is very nice software and now that it is free it is really a great
deal. The pop-up
ad you have to sit through is for the L/C Meter IIB. I have both
this one and the
original one and they are absolutely great little devices. Pricing
of MFJ equipment
with quality and accuracy that MFJ only dreams of.
You can check out error analysis here: http://www.aade.com/lcm2binst/HP.html
Specifications are here: http://www.aade.com/lcmeter.htm#specs
And you can even download the instruction manual to check it out in
more detail.
This explains why the program is free:
The program has been a hobby of mine for over 25 years.
For the last 7 years I sold it as shareware but total sales for those
7 years was less than one months sales of my hardware so I decided to
give it away to attract visitors to my web site and call attention to
my hardware products.
I don't know this guy, I've just been a VERY satisfied customer for MANY years.
