FM-25 Info.
Ramsey trying to go to the next level with it's FM xmitter kits
has released the FM-25. It is a true synthisized stereo FM broadcast
transmitter. It offers frequency stability not obtainable with
inductor/capacitor free running oscilator based circuits like the
FM-10 and others. The FM-25 has an export power option that brings it's
output power to about 60mw and the FM-25 is very easy to build
even though the part count is high. Once again Ramsey has done a great
construction manual, the strongest part of both the FM-10 and FM-25 kits.
The FM-25 does leave alot to be desired. The output power is too great
for the final RF amplifier stage. The supplied power supply and case are
a little better than junk. Some of the circuit can be slightly modified
for greater performace in both output power and sound quality. Soon
I will be exploring solutions to some of these problems. John Ramsey
was kind enough to demo me a kit, and I will be building it shortly.
Nothing here yet except:
