Hi qldbureau
Thanks for the update

It's the smaller things I am having a little trouble with. The led on the Rx board will not blink. Even testing the pins with my multimeter I am not getting any voltage pulses. I used header pins for that one so was easy to swap leads around.

The RX v4.03 board have two leds. I think you are talking about the one in the upper left of the board. That led only blinks when you have comunication with Cumulus. If it not blinks when you are connected to Cumulus, check the LED position.

On the Tx board again the tx led is not blinking, and I am not getting pulses past T1 - so not sure if T1 is damaged.

If you are receiving data, T1 is working. It not only drives the LED but also the transmitter module.
Pulses are very short, but anyway they can be seen. Remember, T1 will switch on and off the GND line of the transmitter module and Led, not the active 9V line. Sometimes this makes some confusion, and leads to assemble the Led in reverse.

I am going to use a radiation shield fan, for which to test I made the high temp 23 degrees. With temp reading at 28 I am just not getting voltage on the fan pins or at the led. If I measure voltage across diode 1 I am getting 9v.

Unless is a bug , this can be just a software config problem.
Just for testing, until you have an anemometer connected to the TX unit, in user config options, please change this line:
#define ID2 // Wind data
to
//#define ID2 // Wind data

compile and upload.

So a little ironing out to do here, but not where I was expecting! Overall I'm going well.

Congratulations, you are going very well!
Let me know if any of my hints helped.
