Re: K4D and 2 Meter EME

Bob McGraw - K4TAX
 

Since there are 2 receivers in the K4D-F I would think each receive BNC from the transverter IF1 and IF2 would connect to the two receivers on the K4D.   Now this says to me there are two receivers in the transverter thus there are 2 IF outputs at 28 MHz.  And there is a common input for the 28 MHz signal for transmit.   That's the way the pictures look for the transverter.

Transceiver and transverter control is easy and is available with correct switching and ratings on the K4 as well as the required drive power at the correct value.

I've never used a transverter with provisions for 2 antennas.  All of mine are DownEast Microwave of which I have 3 of them for 144 MHz, 432 MHz and 1296 MHz.  At present I only use the 144 MHz unit with my K3S.  Works great.

All of this raises questions with me, such as does the transverter select the proper polarization antenna for transmit?  And is there provision for transmitting on both vertical and horizontal antennas simultaneously?  Running a power amp would then require a power divider to feed the two antennas.   I ran a 8877 at about 1500 W  out on 2M and about the same on 432 MHz but with a different tube.   Are the outputs of the two receivers combined into one 28 MHz signal or is two separate IF's needed?   

As you can tell, I've never used or been concerned with polarization with any of my EME operations.    Besides that, the 128 element array {8 x 16} I had on 2M is not one you would want to rotate from horizontal to vertical.   EL-AZ is enough to manage.

Hope this helps.

I am looking at the K4D-F and want to make sure it will interface to my two meter EME transverter.

 

A simple transverter with one transmit and one receive line from the antenna would be easy, but for two meter EME I am using a ME2-XP transverter which has two receive BNC connectors to a transceiver (separate horizontal and vertical receive antennas) and a single BNC to the transceiver for transmit. (www.ha1ya.hu/pdf/ME2XP_manual.pdf).

 

Looking at your sales brochure from Dayton, I assume Transverter transmit would be from XVTR IF Out, my first receive only antenna (Horizontal) would go to XVTR IF IN, but I am not sure where I would connect the second receive only antenna (Vertical).

 

PTT Contact Closure to Ground is required for the transverter.

 

IF drive power is -20 to +37 dBm.

 

If you would help me understand the antenna connections to make sure everything can connect properly and the drive levels / PTT are compatible - I would really appreciate it.

 

I looked online, but could not find any info on the XVTR possibilities.  I plan on ordering next week.

 

Thanks

Re: [Elecraft] K3 Key Out Jack Not Working

Bob Wilson, N6TV
 

The KEY OUT jack GROUNDS the center pin, whereas a shorted phono plug simply completes the DC relay circuit between shield and center (without grounding it).  That's probably why it doesn't work.

inverted L unless PTT is asserted.  The lashup is complete, and works
when I short the phono plug manually, but not when I plug it into the

I'm hoping it's just a menu issue, but my manual doesn't show any menu

I assume the basic functionality is OK.  Any advice?  I'd really love to

Re: K3s Remote

Bob Wilson, N6TV
 

Among other tricks, the "Serial Box" (S-BOX or S-BOX-USB) offers a plug and play solution compatible with RemoteHams software (or simple Windows batch files) to power a  K3 ON and OFF remotely.  With the S-BOX, power ON is done by toggling the RTS pin of the serial port HIGH and LOW (a bult-in feature of the RemoteHams software).  Toggling the RTS pin high momentarily grounds Pin 8 of the ACC port via a 2N2222A keying transistor inside the S-BOX.  No relays or web switches needed.  TeamViewer will work fine.

Power OFF is done by sending a PS0; command to the radio's serial port.  You can do that with a batch file or with RemoteHams.

More details including a block diagram and schematic are posted here:  https://www.kkn.net/~n6tv/S-BOX/Features.html#RemoteHams

The S-BOX includes a total of four 2N2222A keying transistors, so two more can be used to provide FSK keying and PTT via Pins 1 and 4 of same K3 ACC connector.  Genuine Amphenol® 9- and 15-pin shielded cables with molded connectors may be supplied with the S-BOX if needed, providing a complete plug and play solution for RemoteHams users.

Re: K3s Remote

Rick Tavan
 

You could use a remote power switch to turn off AC power to the K3 power supply. The one I use is from Digital Loggers (no relation to ham radio "loggers") https://www.digital-loggers.com/. It looks like a typical AC power outlet strip but also connects to your network and presents a Web page user interface. I found mine many years ago at a surplus store and it has served me well ever since.

Re: K3s Remote

Michael Foerster
 

Jeff,

I use RemoteHams.com for my K3s/KPA500 to remotely control my station.  I do have some extra circuits at home to switch antennas from the K3 band outputs, but your KAT500 may likely give you that functionality.

In order to turn the rig on, you need to connect a transistor (2N2222, or any NPN) from the RTS pin of the Serial port for the rig power on control.  Power off is through comms.

https://www.remotehams.com/forums/index.php/topic,1630.0.html

You can install both the Server (to the rig) and the client (for remote control).  The software is free, but they do as for a donation.

I’ve been using it for years and it works great on both Windows and Android (remote from the car!).  Doesn’t work on MAC or Linux.

73,

Mike, W0IH

Re: K3s Remote

From memory (variable these days), the K0 (kay zero) command turns off the K3.  To save power, there is no power on command (the cpu would have to be fully awake and that would raise consumption). 

I have a USB relay and a short script for it to momentarily tickle line 8 on the ACC cable for K3 power on. 

An icon on the main display runs the script with a click then TeamViewer management, of the PSTRotator, KAT500, KPA(1)500 utilities, plus HRD for the rest. 

Easy peasy.

After many years of service, the Astron’s output voltage had sagged a bit, plus I was running the K3 through a DC distribution panel.    I adjusted the output voltage of the Astron to 14.5 VDC, eliminated the DC distribution panel and now my K3 reports  14.2V input in RX.   No reoccurrence of the problem since.

After many years of service, the Astron’s output voltage had sagged a bit, plus I was running the K3 through a DC distribution panel.    I adjusted the output voltage of the Astron to 14.5 VDC, eliminated the DC distribution panel and now my K3 reports  14.2V input in RX.   No reoccurrence of the problem since.

 

Worth a check …

Hi,

 

Has anyone had this show up on their K3? It was “E 017878” which eventually worsen to no audio or transmit. A check with the K3 Utility show that the DSP portion of the firmware not loaded (DSP1, DSP2). Reloaded the firmware and all seems to be well, but I am concern about the E1017878 notice.

 

Thanks
