<pre wrap="">Look for "Kenwwood TM271 Manual.PDF" . As usual, left-clicking the link
will try to open the PDF in your browser, while RIGHT-clicking will
offer to "Save Target As... " which is usually what one wants. It's a
1.25MB file download.

Thanks. I tried getting it off their site at home and at work, and both
places got a 0-byte file.

If so, I'll know soon enough. I know a local Kenwood dealer... I'll see if
I can get a part number for the connector if it's not something with an
obvious equivalent I can get form Digi-Key. If the pads and everything are
there, I'll document the procedure and post pictures of the process.

<font face="Arial">Based on my previous experience with this sort of
stuff, you'll have to acquire a service manual for the TM271; i.e.
$25-$30 additional purchase. Normally Kenwood's service manuals
document all national destination variations of a model , though the
coding schemes they use are sometimes confusing and ambigious. <br>
Usually there will be more than one set of schematics and board
X-rays that will show different parts added, missing, or changed
depending on destination. <br>
For example, UHF rigs almost always have a gridded table showing
different value inductors and/or caps depending on whether the radio is
destined for Europe (430-440 MHz coverage) or North America
(440-450). 2M models sometimes show a different set of L and C values
for US vs Euro for the same tuned circuits in RF stages, to acheive a
lower-Q broader tuned circuit. (The Euro 2m band is only 144-146 vs our
144-148. )<br>
<br>
Note that in some cases, you will see THREE variations: The Euro
version (144-146 only with 1750 tone burst capability only), the US
version (144-148 with PL encode/decode, touchtone support, and
crossband repeat in the case of dual-banders) and a third version for
Japan and Australia (144-146 coverage only, but US-style features like
touch tone and PL.) <br>
Usually the region frequency coverage can be changed by adding or
removing nasty little surface-mount diodes or resistors and then
resetting the CPU. ( <a class="moz-txt-link-freetext" href="http://mods.dk">http://mods.dk</a> is the prime source of info on
these "hacks". )<br>
