He said "extended crusing in the Pacific" and wants to use a 25 year old
12-chan SSB with crystals. It's quite foolish to contemplate such cruising
with an archaic, limited radio upon which one's life might depend. It's
prone to failure, and parts and repair services are next to impossible to
find. Extended crusing means the sensible mariner will want to tap into
weather nets, cruiser nets and the like -- all kinds of frequencies which
may not be known in advance for which crystals are unavailable. Advice: Get
a modern SSB and be done with it. If money's the issue, work a few weeks
longer.

Who's Ken?

And just what did you contribute Chuck? Zip. Nada. It figures.

Sir, If you had a clue, you would be DANGERous. Those old channalized
Marine MF/HF Radio's are mostly built with discrete components. Much
easier to repair than the modern Surface Mounted components, of todays
radios. Furthermore Marine Techs have years of experience, with those
old radio's and the modern ones are basically "Factory Board Replacement"
if the factory still stocks the boards. Nothing wrong with a 12 Channel
channelized radio, for the simple reason, there are very few channels
that are for use by NONcommerical Maritime Users in the MF range, and
not that many more in the HF range. Most of these radios use A/B
channelization, which allows for two frequencies on each channel set.
This covers better than 50% of the available frequencies on each band.
The solidstate versions of these older radios are as trouble free as
any of the in-production radios of today. The Northern Radio Co.
571 is one such radio, and it is BUILT like the proverbial "Brick
****house". The PA in that radio is HUGE, and will output 100W
Carrier into ANY LOAD, forever.(Or untill the Batterys fail) Try
that with ANY modern Marine MF/HF SSB Radio? What you'll get first
is powerfoldback to 25W, due to the missmatched load, and if you
could get it up to 100W, the smoke would soon drive you out of the
cabin due to meltdown of the PA.

Bruce in alaska who actually installed a PILE of these over the
years.
