Thank you Alan.
Any laser type link will be home constructed, it will be strictly PWM
and the range will be point to point from my shack weather station pole
to a high point on the house.

Hi Hugh they can create horrendous RFI if you are not careful. The
ones used for TV distibution "may" be better......the good ones are
notched at the amateur bands and being for digital levels dont use AGC.

To avoid having laptop running in the shack, which occasionally
produces some QRM, I can send received audio from the shack to a
desktop computer in the house on a twisted telephone pair. This works
but any wire connection between shack and this desktop introduces
some spurious signals on 136khz even if I use an audio isolating
transformer.
