I saw on the site a "mod" to set the radio to one of
the preset channels...if you read the manual you see
that you can set it to any frequency in the range of
150-157 something if you send it to an "authorized
service dealer".
The secret he knows is the "Set" button, a small
surface mounted button located in the radio, hidden
inside the radio. This button is the "secret" to the
rest of the frequencies. In the BTX-127 I believe it
is right above the DIP switchs(I dont own one, I own
their "2 channel mobile radio"...a good
purchase/project (bring it down to 2 meter ham band?)
from radio shack recently, as the price has been
reduced to $20
Anyhow, enough of my babling ^_^
This mod is valid for all of Radio Shacks programable
Buisness Band Radios...the frequency bank will differ,
but most likely the same banks
This was tested on a Radio Shack "Buisness Band Mobile
Tranciever"..it doesnt physically do anything, so feel
free to test it on any other radio
1)Using a screw driver, carefully open the radio and
locate the set button. In the "Mobile Buisness Band
Tranciever" it is under the top cover, to the lower
left(with the channel switchs facing towards you), in
the BTX-127 it is right above the DIP switchs under
the cover..."set" is silkscreened right next to it
2)Find the DIP switch set used to program the
radio...in the BTX-127 the DIP switches are under the
battery cover, in the Mobile Tranciever they are under
the radio, under a small door...the manual will say
where to find these switchs, as they are used to
program both the preset frequencies and the CTCSS
codes
3)Using the Frequency Bank (attached to this e-mail),
look up the codes for the frequency you want to set
the radio to. Set the switchs to the settings for the
first bank (0=off, 1=on) and press the set button. The
radio will beep once. Now, enter in the code from the
second bank for the same frequency and press the set
button a second time. If the radio beeps twice, you
did it right, if it beeps three times, you did
something wrong, try again
4)Turn the radio off and set the DIP swithcs to their
previous settings.
*IMPORTANT NOTE*:This frequency is programed in
another frequency, and as a result DIP switch 2 must
be set to the *on* position for the radio to use the
custom frequency. However, if you flip DIP switch 2
back to 0, the radio will revert to the preset
frequency you programed in using the traditional
programing method...this can be useful to make the
BTX-127 into a two channel radio, and the mobile base
radio at least a 3 channel radio(have not tested if I
can program in the second channel as well)
