Field Marshall Tracking Receiver
What is a KHz and a MHz?
These are measurements of frequency. Every transmitter has a
unique frequency that makes it distinguishable from all others.
Fortunately, a receiver can tune into a single frequency at a
time and reject all the others.
The basic measure of frequency is the hertz. It represents one
cycle or vibration per second. A kilohertz (kHz) is a thousand
cycles per second, and a megahertz (MHz) is a million cycles
per second.
An AM broadcast station is fairly in low in frequency, perhaps .7
MHz, while an FM station is much higher, say at 105 MHz. Your
telemetry operates at a still higher frequency, such as 216.055
MHz. Thus, a single short pulse from your transmitter is made
up of several tens of millions electro-magnetic vibrations.
The kilohertz unit is usually used in telemetry to measure the
difference between frequencies. For example, if you had a sec-
ond transmitter at 216.070, it would be 15 kHz higher than the
one mentioned in the previous paragraph. .
Is there an easier w ay to get the receiver in and out of
the car.
It's a lot easier if you push the sliding channel closed, partially
collapsing the antenna. However, don't forget to extend it when
using the receiver in order to get maximum performance from
the antenna.
How can I use m y Marshall receiver w ith m y car top
antenna? It's got a different plug.
Marshall receivers use high reliability, lightweight, gold-plated
SMB connectors. Call to order a short adapter that will fit the
larger BNC connectors used on some other antennas.
