Re: [Elecraft] Frequency Not Synced for Diversity Receive

[efortner]

Hi Lee,

I finished putting my k3s together last week and with help from Howard at
the Elecraft discovered most of my problems were coming from a bad tcxo. I
also have the sub receiver and want to do diversity receive with 
A separate antenna. My sub receiver is working but I cannot receive any
signals from the Aux ant bnc port. I do not have the antenna tuner option so
have only the Ant 1 so239 and the bnc port with coax cable going to the rear
of radio into the sub receiver. Maybe have something set wrong. Anyone else
had this problem. Radio serial number 10326.

73, 
Earl, K4KAY

Lee,

A correction to my previous response:

The fix for diversity w mismatched main/sub rx filters was actually
implemented in MCU 5.33 firmware back on 8-3-2015. Of course it's also in
the latest 5.38 firmware as well.

Be sure to set.

Hi Lee,

Make sure that CONFIG: VFO LNK is set to OFF.  Then when you have done a
hold on SUB button, see that the second decimal point is blinking.

Mine currently reads one dot eight one seven dot six seven. The dot between
seven and six is blinking indicating diversity mode.

You do not have to link VFO's to enable diversity. Diversity does not use
two linked synthesizers. It runs both RX off of the A syn. B syn is used in
diversity only for transmit if you are doing "SPLIT" TX.

Good Luck and 73

[Elecraft] Frequency Not Synced for Diversity Receive

[KY7M]

I am setting up diversity receive using the AUX input for my receiving loop.
After holding the SUB button to turn on DIVERSITY, the speaker output is
obviously off between MAIN and SUB by a hundred Hz or more.  I can hear the
same signal on the other speaker most of the time, but the tone is quite
different.  I installed a pair of new synthesizer boards several months ago
and all else seems to be working properly.  Any suggestions?

 

Lee, KY7M

Hello Lee,

Make sure that you have installed the latest production firmware (MCU
5.38)  for your K3. There was an issue related to using dissimilar filters
in the main and sub-receivers, which caused what you are experiencing.
That has been fixed, first in beta firmware a while ago, and now in the
production firmware.
