Re: K3 Sub Receiver Deaf

There are multiple ways in which the input of the sub-RX can be wired. It's been 13-14 years since I did mine, so don't remember the details. Check the manual for the sub-RX. Probably in the build-install instructions. Everything is on the Elecraft website.

Thank you very much for the interest and replies.

Sandor,
Thanks for suggestion to use the  Elecraft Frequency Memory Editor.  I used it and was able to enter the frequencies and modes correctly.  Thanks again. Best 73,  Roy  W4WFB


Re: Programming 60m channels in K3

Hello Bob,
I was unable to get the CW mode and frequencies to hold in memory when programming directly into the K3.  I loaded the Elecraft Frequency Memory Editor and was able to accomplish the correct settings.  
While I was looking in the Fred Cady manual I saw this and implemented it:
The CONFIG: MEM  0-9 menu allows you to change how recalling a general purpose 00-99 works. Normally, as you rotate VFO A to select a memory, the K3 switches to that frequency as soon as you stop turning it. If, in the CONFIG: MEM 0-9 menu you tap [1] and select M>V DLY, the receiver will not switch to the new frequency until you tap M>V.  I no longer hear the relays clicking as I rotate VFO A through the bands, especially if I rotate slowly.  Maybe this will save wear and tear on the relays.
Thanks for your reply.  Roy  W4WFB

First thing to do is to check all the small TMP RF cables. It's quite possible one isn't making good contact. It's a bit of a pain to get to the ones associated with the Sub, but you need to get in and use a pair of small needle nose pliers to CAREFULLY pull out and reseat each connector.

The sub recvr is not hearing the signal in the right speaker earphone from the single antenna when it's set to the same vfo signal as the A vfo.

So it seems that the sub is working, just not connected to the antenna or the audio is not being heard.
And it does hear hiss in the right earphone when the sub recvr is turned on.
The right earphone does hear audio when the sub is turned off and the config is set to 2 speakers.
The coax is all plugged in as far as we can see, except we cannot see under the 100 watt amp to see it plugged into the ATU 1 socket. But we're pretty positive it is. That was not touched when the KIO3B and new synths were installed.
What I am asking for is ideas due to Config, settings, etc. as to what might not allow the sub to be heard signal wise. All else is working after installing the IO3B and new synths.


Re: K3 Sub Receiver Deaf

Colin Smithers
 

I had this problem once. After going through the manual very carefully a number of times and changing the antenna configurations around a lot, I realsed there was a large loss in one of the signal paths. It turned out to be a blown PIN diode, almost certainly my fault, although I don't know how I did it. Too much RF into one of the ports probably. If you can access another similar K3 this will be very helpful, so you can compare good against possibly faulty.

But working systematically through the settings is the first task, and isn't super easy.

Good luck,

Re: K3 Sub Receiver Deaf

Geert Jan de Groot
 

The subreceiver may receive antenna signals in a number of ways. Check "Sub Receiver Antenna Selection" on page 50 of the KRX3A subreceiver manual and "Main and Sub Receiver Antenna Routing" in the K3 manual.

You did not document your K3 configuration, depending on the hardware the sub RX may listen on the aux RF port (if your K3 has it) or even on the other antenna socket. Check the manual.

I ran into a situation like that and some setting linked or unlinked the RF or AF gain of the two receivers.   Or some squelch setting.

This may not  apply, but do you have two new synthesizers. One new on the main, and one old one the sub, will not work properly

Re: Programming 60m channels in K3

Please re-check your frequencies per the band plan.  CW should be the center channel frequency and USB should be the lower channel frequency. 

Yes, the K3 Editor is the easier way to load the frequencies into memory.

There is a Memory Utility on the software page for the K3/S.  I programmed mine by hand first then used to utilty to read the radio and save the memory file.
