This macro simplifies switching the K3 into diversity receive mode. This K3 configuration and antennas are required:
1) KRX3 second receiver 2) KXV3A or KXV3 RF I/O module 3) The main TX antenna is used for receive along with a separate RX antenna.The RX antenna is connected to both the KXV3/A RX ANT input and the SUB RX AUX RF input via a BNC T adapter or Magic-T type 3dB splitter. The RX antenna is the default receiving antenna - the RX ANT button's state shows RX highlighted on the display. Here's the macro: SWT13;SWT13;FT1;RT0;XT0;UPB4;DV1;SWT25; VFO B is set to VFO A all parameters; Split TX is enabled; any RIT/XIT offsets are zeroed; the split frequency is set to 2 kHz up; diversity mode is enabled; the RX ANT is disengaged to allow the main RX to use the TX antenna for receive. Note SWT25; toggles the state of the RX ANT button. The macro assumes it's enabled before switching to diversity RX. If you have two separate RX antennas/arrays, connect one to RX ANT and the other to AUX RF and remove SWT25; from the macro string. To turn off diversity receive use this macro: DV0;SWT25; This OFF macro also switches the main RX back to the RX antenna from the TX antenna or to the dedicated RX antenna connected to RX ANT. I set the first macro to Tap-M4 and the second to Hold-M4. This dedicates a single button to control diversity RX ON/OFF. This diversity ON macro eliminates the need to hold the SUB button while the K3 syncs VFOs and enables diversity mode. If operating split while in diversity mode, to hear and adjust your TX split frequency, hold the REV button and tune with VFO A not the sub VFO B knob. Release to listen to the station of interest. If you haven't tried it, the K3's diversity RX capability is a very valuable low band weak signal receiving tool. 73 - Steve WB6RSE ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
