PARC 50 LBS

Getting close to completion now.  Spent some time laying out the boards and making a few changes from the original layout.  Can't believe with a 20" x 12" board I'm running out of space. hmm.

I thought I had all the boards done except for the rx pre amplifier.  It may not be necessary, but I need to make provision for it.  I need to make the board for the tx/rx relay.  Wish I remembered that when I did the board for RLY3. 

Pretty much ready to power up the final amplifier board.  Just need decide if I chance it tonight or tomorrow. All the talk about the heat that is generated with this circuit seems to have got me concerned. Well maybe I'll record the power up and if something dramatic happens, well it's entertainment.

LPF for the LBS Project

Built 4 boards the last few days.

1 LPF for 40
2 Microphone Amp
3 RLY3 board
4 Pre-driver final amplifier

The LPF 1st -3db level is at 9.250.000. Ran out of time today take a closer look at the curve and make any adjustments.

I built some flexibility in the mic board as I'm not sure which mic I'll be using. Either a Yaesu mic with some buttons on it that I may use or a Kenwood mic with no function buttons.

I still have to deal with power supply cables in an orderly fashion instead of the birds nest that's in use now. As well a pre amplifier for the rx function is still to be designed/built.

Anyway can see the light at the end of the tunnel and should be getting this rig on the air sometime in January.
