Beyond 30 Mhz - Ten-Tec SSB-CW-AM Instruction Manual

Beyond 30 MHz . . .

Your Model 1254 can be used with a receiving converter or even
a transverter to receive VHF signals, particularly on the amateur
6 meter (50-54 MHz) and 2 meter {144-148 MHz) bands. The
following T-KIT products will work nicely with the Model 1254 to
permit monitoring of the 6 meter and 2 meter bands. Keep in
mind that transverters are designed (and priced) to handle
transmit as well as receive frequency conversion.
T-KIT Model:
1061 6 meter converter
1208 6 meter transverter
1210 2 meter transverter
When used with a converter or transverter, your receiver
becomes what is known as a "Tunable IF". You need to
translate the indicated frequency of your receiver to the intended
conversion frequency.
. . . and Below 100 kHz!
We did NOT design the Model 1254 to receive signals below 100
kHz. The microprocessor control of the frequency synthesizer
stops one step below the 100 kHz limit, which would be 97.5
kHz in SSB mode or 95 kHz in AM mode - OR "0.000.0" kHz
when tuned one step down in FAST tuning mode. When you
reach "000.0 kHz" using FAST tuning, you will hear the very
strong 45 MHz 1st LO signal, intended as a test signal during
receiver construction. From this point, you can switch off FAST
Tuning and tune UP in 2.5 or 5 kHz steps, but NOT down.
There indeed ARE some radio signals below 100 kHz including
WWVB at 60 kHz in Colorado, possible NASA-sponsored
experiments and miscellaneous RF devices. We remind you that
this tuning capability is beyond the intended design and purpose
of the Model 1254. You will need to experiment with the
sensitivity below 100 kHz.
