PSK Meter - My take on the KF6VSG PSK meter from SSIServer.com

The KF6VSG PSKmeter from SSI Server is a fantastic meter kit can very quickly help you tune your digital mode signals to achieve the lowest possible IMD or inter modulation distortion levels. The kit is well built, pretty easy to assemble, and just works in Windows and Linux. I do think the kit is it's a little bit on the expensive side but it's well worth it. Anyway, this page is to document two changes I made to my unit:

Added an externally accessible switch similar to the previously posted mod on the SSI Server's website:
Added a power LED to know when the unit is powered on. To support this, I split apart a jumper post and soldered each of them into the +5VDC and GND test points. I then took an old jumper wire set, split it apart, soldered a 1KOhm resiter to an LED and SuperGlued the LED right next to the DB9 connector.
To do: I feel the unit needs a reverse polarity protection diode as it seems one mistake and the voltage regulator component will smoke!
Back in November, 2009, I emailed Martin Ewing who is the author of the Linux pskmeter code on my Centos 5 which he added to his website. I again reached out to Martin on 09/29/10 to see if he would consider adding BPSK63 support since the new Windows program supports it. We'll see!
