Graham,
Many thanks, I wasn't aware of the filtering below 490Khz.
However, I was aware that I could get a 0dBm output from the transverter
port, as I already use this with a very old Microwave modules 28/144
transverter, I even get 7Watts from it with nothing but the std Low power
jumper installed on the MM transverter. It works a treat.
I was having a problem of figuring out how to get an output in an area that
is not part of the Ham Bands.
I assume its just a case of setting the Antenna setting for say GEN to the
Transverter port.
I need to hunt out some of my old 1970's PMR taxi radios and rob them for
the 455Khz IF strips!
Sounds like a plan.
I'm not the most technical type, and sometimes just need some confirmation
or pointing in the right direction!
Many thanks for the hints and help.

Geoff:
If you are going to operate the Flex-1500 below 490 kHz, you must supply
your own external receive bandpass filters. The internal filters stop at
490 kHz. You will also have to supply an external transmit power amplifier
that will accept the 0 dBm onput from the transverter port. The 5 Watt
internal
RF power amplifier does not operate below 160 Meters.

I don't know if this is just my Flex 1500 or if this is a general thing.
When I tune below 500Khz it appears that the display tunes backwards.
Also if I use the Crosshairs, target a signal peak (Below 500Khz), click the
mouse, the display shows the frequency I clicked on, but the station has
disappeared.
If I tune say from 480 to 520 Khz, the display tunes the wrong way until I
get to 500Khz and then it changes direction and tunes the way I would expect
it to.
Also as you approach the 500Khz spot, you can see some images coming
together and merging.
I have never noticed this before, but we are off on an Exped in a couple of
months, and we are hoping to run a 473Khz station. This has put a damper on
my experiments.
My question is simply, is this what everyone else's Flex 1500 does, or is it
just mine?
