Dual Receiver on Single Antenna with Splitter

Postby w1tr » Wed Jul 05, 2017 3:56 pm

With the Apache Labs 100D, you could use a splitter such as the Anzac THV-50 connected as follows:
Terminal B: Common: to Bypass
Terminal C: Split 1: to EXT1
Terminal D: Split 2: to RX2
In the Setup / General / Ant/Filters / Antenna, enable the EXT1 checkbox.

The 8000 DLE does not appear to have BYPASS or EXT terminals on the rear panel,
nor does it have CheckBoxes in the Setup / General / Ant/Filters / Antenna to enable the EXT1 or EXT2...
The XVTR issue is dealt with elsewhere...

QUESTION...
IS there a way in the 8000 DLE to use RX1 on ADC1, RX2 on ADC2, receive on ONE antenna using a splitter or other arrangement?
I use it for monitoring dual channels on USAF MARS...
but might want to monitor 10 meters while working 160 meters using a 160m dipole.

Terry,

There is no way to do what you want on the 8000 without provisioning an external T/R switch.

If you did provision an external T/R switch, you could then set it up so that TX is on ANT1, RX1 is on ANT2 or 3, and RX2 is on ADC2.

ANT1 would be connected to the T port on the switch. The R port on the switch would go to the power divider. The outputs of the power divider to ANT2 or 3 and ADC2 ports, respectively.

You would have to be most careful to avoid accidentally enabling ANT2 or ANT3 for transmit, of course.
