FM25B: Professional Synthesized FM Stereo Transmitter Kit
Need professional quality features but can't justify the cost of a commercial FM exciter? The FM25B
is the answer! A cut above the rest, the FM25B features a PIC microprocessor for easy frequency
programming without the need for look-up tables or complicated formulas! The transmit frequency is
easily set using DIP switches, no need for tuning coils or "tweaking" to work with today's digital
receivers. Frequency drift is a thing of the past with PLL control making your signal rock solid all
the time - just like commercial stations. The FM25B's real claim to fame however is the use of the
latest cutting edge stereo generator on the market. The audio quality is excellent with amazingly
good stereo separation to keep even the pickiest audiophiles happy! Connections are as good as they
get; use the provided cable to interface with the line output of any CD player, tape deck, computer
or mike mixer. Just build it, plug it in, and you're on the air!
TM100: Tru-Match FM Broadcast Antenna Kit
We've been besieged with calls asking us where to get a good quality FM Broadcast antenna. Well, we
put one of our best RF engineers to the task and came up with this killer of an antenna, we call it
the Tru-Match 100. Why Tru-Match? Because matching your antenna to your transmitter is the single
most important link in your transmitter set-up - and a good antenna and match is the secret to
getting maximum range. When we say match we mean electrical impedance match... if the proper
impedances are not maintained between transmitter and antenna, power is reflected back away from the
antenna and back into the transmitter! This can cause the final amplifier stage to be damaged, not to
mention a spurious signal and lousy range. In real commercial transmitter installations, it is not
uncommon for the antenna matching equipment to actually be larger in size than the whole transmitter
itself!
