VFO 1000 UNIVERSAL REPLACES THE HF OSCILLATOR IN
RECEIVERS THAT HAVE A SEPARATE OSCILLATOR TUBE.
MOST HAMMARLUND, EXCEPT THE HQ129-X, SOME
HALLICRAFTERS AND NATIONAL,
INCLUDING THE HRO SERIES, USE A SEPARATE
UP TO 30MHz.
IT CAN ALSO FUNCTION AS A
TEST SIGNAL GENERATOR
No modification to
the receiver is
the VFO 1000, tuning SSB is a snap.
Most hams operate on even 1KHz
frequencies. So using the 1KHz
tuning step, SSB signals are received
without careful tuning as required with
analog tuning. Usually no tweaking
is required. Use the 5KHz tuning
step when tuning shortwave
broadcast. All tuning is done using
the VFO 1000. The receiver main
tuning dial becomes the preselector.
So simply tune the VFO 1000 to the
frequency you want, and peak the signal
using the receiver main tuning.
Tuning steps available are 10Hz, 100Hz,
1KHz, and 5KHz. 10Hz and 100Hz for
tuning SSB, and 1KHz and 5KHz for AM
shortwave broadcast tuning, or just
getting across the band faster.
There are 30 tunable memories. In a
sense there are 30 VFOs. As
programmed from the factory, the 30
memories are used to step up or down in
1MHz steps, making getting from band to
band faster. Programming can be user
re-programmed to suit your needs.
You can re-program it to step directly to
the bands you use. Some memories can
be used to store your favorite
Installation is by removing the oscillator
tube, then using the included cable with a
pin and ground, insert the pin in the tube
socket, and clip the ground wire to the
chassis. I will tell you what pin on
your receiver. No soldering or
modifications to the receiver are
required. The power supply is
Tell me what receiver you want to use it on and
I will confirm that it is, or is not compatible
with the VFO 1000.
