Yea, they have been simulcasting paging, including tone and voice
here in this country for MANY years. UHS Oscillators and offsets of
1 to about 8Hz causes any nulling that will happen in overlap areas
to move around in the overlap area. It is very important that ALL
audio be as perfectly in

I think that they may be concerned about off

I have a Kenwood TKR-740 that I would like to program up as a backup

frequency rounds up to 146.000. Does anybody know if there is a key
combination to enter a receive frequency below 146.000?
Thank's for any help.

well the TKR-740K should do 146 to 162
K2 should do 158 to 174
K3 should do 136 to 150
all above are RX
all do TX 136 TO 174

Thanks. I must have been brain dead today. I forgot that the RX has
3 ranges. Set it up for the other range and retuned the VCO/front
end. Works fine.

Here is the preliminary schematic. Because the synth chip in the
radio uses +9 V for some reason, this will have to be a board with SMD
parts on it instead of a single chip.
The plan is for Channel 1 to start at 223.85 with 10kHz spacing and
channel 201 starts at 222.15 MHz. There will be

Michael,
Thanks for the additional info. The soft power meter on the HP8920 service
monitor goes down to 4 decimal places
maybe this will be useful for low power testing.

catalog (From 1982, no less. It is hard to throw this stuff
away).
For those who are interested, the 7R011 is specified
at 125 watts. The insertion loss is .9 db typical with
1.3 db max. The isolation can be as high as 60
