Title: Bauer 707 75M / 160M conversion
Post by: kc4mne on September 25, 2011, 02:26:56 PM
Hello,

I am converting a Bauer 707 to 75M / 160M. Need help with component values for building a tank circuit to go between the 6CA7 driver and the grids of the 4-400's? What is the input impeadance of the pair of 4-400's?? 

Thanks

KC4MNE

Something about the Bauer that makes it a fascinating TX...........Nice layout of components and the wide slim metering.

or try to get in touch with Dave (K2DK) He loves those things and has at least 2 or 3 of them.

Talked to Dave Sat night.  His antennas are only up about 30ft after the recent storms.  So, he's only running his DX-100.  He is only going to be in Va until about the end of Oct.

I was going to suggest the OP contact Dave about the Bauers.

How can I get ahold of Dave, K2DK? His email from QRZ bounces back. I am stuck and need some help.

Dave, K2DK wrote a lot of those BC conversions up in Electric Radio.  I don't have the master list handy, but I believe the list is available electronically on-line.   The article may list a current e mail address as well.
