Re: Elecraft Digest, Vol 201, Issue 14

Tom - I will give you some unsolicited advice-- The KRC2 was the worst RFI sucking piece of gear I ever owned.
I think that being hooked to the guts of the processor in the K3 was a killer -no amount of fiddling would calm
it down. Was "usable" at 100 watts but my 80 meter antenna runs across roof about 15 feet above my shack
and it would go berserk on 80 at 1500 .I ended up buying BCD to serial boards from UNIFIED MICROSYSTEMS
they are opitcally coupled and just take the BCD out of the K3 - They also sell hi side relay driver board as well -

https://www.unifiedmicro.com/decoder.html

In my case I put both boards inside the control box for my Array Solutions Ratpack 6 antenna switch. It has been
bullet proof . (and a hell of a lot cheaper than a KRC2 )

| Subject: [Elecraft] Test Report on Running WSJT-X with Apple Silicon
| using a KX3
| Message-ID: <[hidden email]>
| Content-Type: text/plain

| There are a variety of reports on doing this ranging from it being impossible to
| no changes are required. In my experience it runs perfectly and is a joy to
| use. There is only one difference between using Apple Silicon and any other
| Mac.

| My setup is:

| KX3
| Base configuration M1 Macbook
| Apple thunderbolt to USB cable
| Standard Elecraft USB cable for the KX3
| Sabrent Sound Card dongle
| Anker self powered USB hub
| WSJT-X 2.2.2 for the Mac as downloaded from the WSJT website.

| The only unusual requirement is that the instructions for changing the memory
| size given in the software instructions will not work for M1 Macs. Instead you
| use the following commands in the terminal:

| sudo sysctl -w kern.sysv.shmmax=104857600
| sudo sysctl -w kern.sysv.shmall=25600

| The command

| sysctl -a | grep sysv.shm

| will verify that the change is made. At the moment the above must be done on
| each reboot.

| That's it, otherwise it works just as it does on an Intel Mac. I have my serial
| port set for 38,400 baud, 8,2,none and am running full CAT control with rig
| split enabled.

| It appears as of today, January 7, that the Fldigi folks are still working on a
| version that will work on Apple Silicon. In my testing the latest standard Mac
| version would not load.

| ? The sun has been blank.? Six days now without a spot.? I thought we

| Message-ID: <[hidden email]>
| Content-Type: text/plain; charset=us-ascii

| Hello all,

| I would like to have PTT out signal from my K3 that is ONLY activated when the
| internal K144XV transverter is transmitting. I thought I might use the KRC2
| with the K7MDL mod where the 8R signal is used to generate a band specific PTT
| output. The problem: where do I find an 8R or equivalent (I guess 5R will do)
| signal on the exterior of the K3? Can a pin on the ACC connector be used for
| this purpose?

| BTW, I tried building a small interface that activates the amp PTT when a 5V
| shows on the transverter output. Problem: 5V is on transverter output when K3
| transmit on any band.

| Other ideas?

| Thanks,

| Martin,

| I have not done it, but the major problem I see is the question of "how
| to get the signal inside the enclosure". There is precious little room
| on the rear panel. You could go through the right side panel depending
| on how you locate the oscillator with respect to the transverter.

| You could first check if you get stable connection using the

| Firmly wiggling the cables (for the 3rd time) resolved the problem.

Simple reason -- it's chock full of Pin One Problems and is unshielded.
Oh, you say, it's a metal chassis. Yes, BUT -- all the connectors are
insulated from the chassis by paint, there's no connection between
pieces of the chassis because junctions are painted, and so on.
Shielding only works if it's continuous, and if cable shields are bonded
to the shielding enclosure at point of entry.

One of the members of our CQP team bought two for W6GJB's contesting
trailer to go along with the W3NQN filters and switch box he also
bought. I spent a several hours scraping paint, making sure all the
cable shields hit the chassis at point of entry, and so on.

One good thing I learned about it -- a single coax between the Aux Buss
and chassis of the K3 and the KRC2 is all it takes for band decoding. No
RFI issues with K3/KPA500/KAT500 to antennas within 50 ft of the
operating position.

I brought all the connections to the relays the KRC2 operates and its
power supply in via a piece of multiconductor cable, wrapped 10 turns of
it around a #31 toroid and I have since had no problems with 1200 watts
to an antenna about 4m above my roof. No special treatment was need for
the connection to the K3.

I may have scraped paint off the enclosure near the screws that hold the
case together when I assembled it. I do that a lot. A Dremel grinder
does a neat job quickly.

I have been using Top Ten band decoders for decades in many different
environments both in the US and the Caribbean and I have never seen an
RFI issue with it. N3RD also offers excellent support. Unfortunately
I am not sure if Top Ten is still in business, all products appear to
be out of stock.

I think that being hooked to the guts of the processor in the K3 was a
killer -no amount of fiddling would calm
it down. Was "usable" at 100 watts but my 80 meter antenna runs across
roof about 15 feet above my shack
and it would go berserk on 80 at 1500 .I ended up buying BCD to serial
boards from UNIFIED MICROSYSTEMS
they are opitcally coupled and just take the BCD out of the K3 - They
also sell hi side relay driver board as well -

https://www.unifiedmicro.com/decoder.html

In my case I put both boards inside the control box for my Array
Solutions Ratpack 6 antenna switch. It has been
bullet proof . (and a hell of a lot cheaper than a KRC2 )

I have 2 KRC2's, one at home and one at my remote. Both have operated
flawlessly, including lots of 500 Watts RTTY contests. I have found
that if I'm going to have RFI problems it always shows up first when
using 500 watts rtty.
One of the KRC2's is hooked to the aux bus from a K3, the other is
hooked to the RS-232 port on a Kenwood TS-590sg, both driving an
Elecraft KPA500 amp.
