hi all,


i just assembled a ramsey fm25b kit and am having some problems
setting the frequency. changing the frequency with the toggle
switches or adjusting L1 doesn't have an affect on the voltage at test
point 1. it is always at ~12.5 volts even when the toggle switches
are set to the low end of the spectrum. the frequency lock light does
come on and the unit does broadcast signal at multiple high
frequencies (104.5, 106.5 & 107.6) but because I can't set the
frequency the device is not very useful in a crowded spectrum region.
ramsey does offer a repair service but i am reluctant to send it in
just because that defeats the intended goal of this project which was
to learn more about electronics.

anybody have a suggestion??

A friend of mine bought one of their kits once and it didn't work. Myself
and another <experienced> party looked his work over. The kit was plain JUNK
in design. He called Ramsey to see about getting it corrected, they wanted
almost twice what he paid for the kit in labor. If you have a schematic,
maybe you could post in Binaries and some of us could look at it and get an
idea of the layout and give you more productive advice.

You may want to check in the alt.pirate.radio news group for
builders of the kit.

Ask your question on the appropriate newsgroup, which is
alt.radio.pirate.
Or ask the Ramsey electronics people with an email.
