Hi qldbureau
Thanks for the update

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.

Of course! I got myself confused and thought that LED blinked when it received data from the Tx board. I've never connected that LED with Cumulus running before. Just tested it with Cumulus on and it's perfect

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.

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

Thank you for your pointers and focusing my attention away from T1. It turns out everything is perfect. I had to go out for a couple of hours (looking at houses), and now came back and found that all my trouble was, that I had lost connection between the positive supply track from pin 15 on the Nano (otherwise labeled Vcc, or Vin, or 9v). Applied some more solder and circuit completed. Tx LED blinking happily, radiation shield fan power at 9.02v present and LED indicator on

I have system data being transmitted properly also - battery voltage and system temperature.

Now I just need to get my rain & wind sensors. My UV sensor is on its way.

As I mentioned we're in the process of looking for a new house to buy, likely in the next 6 months all being well. So when I do get to live weather display it will not be optimum until the move has happened.

Love this Weatherduino Pro 2 I have to say. I have seen the first of the Silicon Chip articles also. Very well done.
