[wxsig] Need t238 help

[Bill Hosking]

Mike, you lost me a bit here. Although a long time ham, well familiar with 
standing waves, I'm clueless on 4-wire phone lines. Unless the humidity 
sensor itself is the problem.
There are loop-through connectors on the X1W2 board. My T238 goes to that 
board (on the roof), comes out of there in about a 20ft run to the original 
temp/wind/rain sensor package.
When I first fired up, it sensed and ran the existing packages fine - I 
received temperature and wind readings right away.
It was not until I went into 'sensor setup' and turned on the humidity 
package that it started hanging up. Unfortunately, I don't have much leeway 
to change any lengths.
What bothers me most is that I cannot get out of the humidity sensor hangup 
now with any method that I can figure out.
