Hi All,
The manual I have for the PRC-47 only shows the use of the M-80 handset.
Is there anything in the PRC-47 that would make the use of an H-250 a
problem? I have several working Vietnam vintage radios (Prc-68A, PRC-25,
PRC-77) and all now have NOS "modern" H-250s with the volume control and
I'd like to also use one on the PRC-47 that I will be receiving soon.
Thanks and 73,
Clare. N2RJB

Hi Clare - The usual handset for the "Old Family" PRC-47 is the H-33 which
has a carbon mic element. I believe the H-189/250's that are often used
with the New Family gear like the PRC-25/77 uses a dynamic mic element and
therefore not directly compatible with the Old Family equipment. And
different connectors of course. (U-77 versus U-229). Also I don't think I
have ever seen an H-250 handset with a volume control. (But I never say
never! haha)
Have fun with the PRC-47. When they work, they work great...
Cheers, Tim

Oh darn, I did it again. I should have written PRC-74 and M-80.
I just tested connecting an H-250 and an M-80 that I purchased years ago,
both connected to a PRC-77. and the M-80 PTT and mic worked fine, good
sidetone in the H-250. But how will I hear incoming audio from the PRC-74
with just the M-80 mic attached? Dumb question but I'm all jazzed waiting
for Gilbert next month (getting the '74 then) and don't want to wait to
learn more.
Oh, one more thing these H-250s with volume controls also come with a
plug-in earbud.
Please excuse all this bandwidth.
And thank you,
Clare N2RJB
