This project has been on the back burner for the last several months while I have been working on the third prototype of the Hi-Q Antenna Controller.

I am designing a combination Power Supply, Connector, Battery Charger and USB board for the N2PK-VNA.  When combined with the existing N2PK-VNA boards, it completes the VNA.  The board provides the following:

1. Filtered Power from external source (+5 and +12),
2. Support for single and dual detector boards,
3. Power from internal NiMh Battery Pack,
4. NiMh Battery Charger,
5. DB25 Parallel Port,
6. External Power Connector,
7. USB Interface,
8. Power from USB Interface,
9. On/Off/USB switch.

Most features are optional (NiMh battery, USB interface).  You can leave out features you are not interested in.

I am interested in any feedback or suggestions you might have on features or issues you have encountered when building or using your N2PK VNA, particularly as it relates to the power supply.  Please send e-mail to N2PK Power Supply Suggestion/Requests.
