[Drake] Drake TR-4CW Noise Blanker Question

[Roland Dorst]

Hello Drake List Members,

have a question to the TR-4CW noise blanker. Perhaps someone can help me
with this .

I've two noise blanker and do not know, which of them will fit in which
type of my TR-4CW transceivers:

# 129,   9/34NB
# 780,   9-34NB

The Drake mods file says, there is somewhat to keep in mind, while
inserting the blanker because of different types. Anyone knows what to
do?
