Hi Homebrewers,
Has anyone ever seen information on modifing the innards of Mitsubishi
M67730's.
The top comes off really easily and the input and output filters (which have
series inductors and caps to ground) seem to have several positions for
fitting the capacitors as though the block is quite wideband and the filters
set the bandpass.
Just an idea that these 30 Watt 170MHz units may easily be moved down onto
2m?
Has anyone attempted this?
Thanks in anticpation
Dave

Might be fun to install a compression type variable cap and see if you
could tune it. It shouldnt be too risky if you keep your drive low.
