Little progress

Last week I worked on the 144 MHz FM transceiver.
See My 144 MHZ transceiver blog
Not much progress to report on the 50 MHz project this week.

I found out that the 50 MHz power module is available at
rfparts.com
This module is the best option. I have looked at other PA's. Lots of PA's can be found on the internet. Unfortunately a 200 mW in 10 Watt out PA suitable for SSB could not be found.

Here is a picture of the current state of the project.

It has 200 milli Watt output. This should be enough to drive a power module. Those modules are hard to get though so I may have to make a PA myself.
TX and RX work. However more fine tuning is needed.
