One step closer to being a ham techie!


 Now that I can use one Signalink USB unit on either my Elecraft K3 or KX3 I thought it was now due time to investigate operating my rigs remote from my laptop using my router. I have read many ham who do this  so it’s not anything new…BUT….for me this is cutting edge and can be “kinda fun” to get it up and running.  I can across software called Teamviewerwhich allows you to remotely access your PC from another PC. Once logged on and a connection is made you have (on your remote PC) a mirror image of your home PC. You have the same control over your home PC as if you were sitting in front of it. The software allows you to access your Windows PC via a Mac and so on. This Windows/Mac cross over was great for me as my home PC is Windows and the laptop is a Macbook Pro. I set out to download and install the software on my Windows PC. It went very smooth and error free, I then installed it on my Macbook pro laptop and all went well until I started the program. The program just
would not start it just got hung up and I had to do a force shutdown. I tried a few things but just could not get the program to run. I then installed it on my wife’s Macbook pro laptop and it operated without
a hitch! The only thing I can figure is my Macbook is a bit older and may not be up to the task. I was on the internet to see if I could see what the issue might be but could not find anything. I am going to email the company and see what their input is. On the weekend I was not interested in troubleshooting or emailing for an answer I just wanted to get the program up and running. With the program installed on both PC’s and it was time to make the link. It is very straight forward to do, you open the program on each PC. You are given a 9 digit ID number on each PC and since I want to use my laptop to control my main PC on my laptop I enter the 9 digit ID number from my main PC and press “connect to partner”. I then enter a password (setup during program install) and in no time I have full control of
My remote PC operation
my main PC from my laptop. Note: if you want to have control of your laptop from your main PC justenter on your main PC the 9 digit ID number shown on your laptop and press “connect to partner” along with the password. After using this program several times I can honestly say it works flawlessly and very smooth. I was able to open Win4k3suite and WSJT-X and make contacts with JT-65 from my laptop. There was absolutely no latency issues, lockup or programs refusing to operate or open. One great piece of news is if you use Teamviewer for personal use the program is FREE!! If any of my readers has ever wanted to toy with remote desktop operation or you are using a program that has issue give Teamviewer a go!

PART2: Mod for Signalink USB so it can be used with 2 radios

The finished product
Below are some of the options I came up with to see if I could get my Signalink USB to work with two different radios……
  1. Rewire the internals of the unit each time I switch radios, this was just not an option as it is time consuming and the unit I believe over time would not stand up to these continual wiring change outs.
  2. To purchase Signalinks plug and play boards, you simply plug in the board for the K3 or the KX3. This is for sure an option but again I was wanting to not take the Signalink apart each time I wanted to change out the radios.
  3. There is also the option of purchasing a second Singalink USB unit but this is very pricey for what I wanted to do.
  4. Try to figure out if it is possible to set up the internals so with the simple flip of a switch mounted on the outside of the unit I could change the internal wiring to make either the K3 or KX3 work. This was the option I decided to work on.

So settling on option 4 as my choice I set you to see if and how it could be done. I did an internet search because the way I look at it is why try to reinvent the wheel if someone else already has! My results turned up only 2 that I could find were the unit was being used for 2 radios. Both did not seem to suit my need. The first seemed the operator configured a device that allowed the use of two of the same radiosbut at different locations. Each radio could be controlled by the same Singnalink unit. The other site I found this op used 3 RJ45jacks in a separate box to do just what I wanted to do…BUT…..I was looking to not have yet another “box” I was ultimately looking for an “all in one” solution. I ended up drawing out many possible circuit diagrams and at one point almost finished wiring what I thought was the "solution". I then realized it just was not

going to work and had to hit the drawing board again.  I finally came up with a workable plan that involved drilling only two holes in the back panel of the Signalink. I had to install a ON-NONE-ON mini switch and a hole for an RJ45 pigtail to be placed. Some of the things I ended up learning as I went along were: 
1. A long pigtail had to be made on the connections between new rear panel switch and the 8 pin DIN wiring. This allow the removal (if needed) of the circuit board.
2. I had to solder the wires into the 8 pin DIN they just did not stay in place and with the extended pigtail there was lots of movement in the wires as the covers were put in place, I didn't want any wires coming loose once assembled.
3. I ended up removing the pigtail and adding a rubber grommet as the plastic housing seem to have a sharp edge to it.
 Below is my diagram for the mod, the "K3 Signalink RJ45" is the internal jack on the unit. The wiring shown in my diagram for this RJ45 is the wiring that is on the circuit board and does not need to be added. Also on the 8 pin DIN there are jumpers between Spk-1, GND-5 and GND-6.  I have tried the unit both with my K3 and KX3 and it works great. The final thing I have to do is just label the rear switch.

Soldered jumpers
In an order to simplify my digi setup with the Elecraft KX3 I wanted to take advantage of my Singnalink USB unit. I currently use it along side of my Elecraft k3 for digi mode operations and I have thus become accustom to how it works. So it only made sense to also use it with the KX3 setup. One major issue I had to see if I could overcome was modifying the Singalink USB device to work with 2 radios? The issue was that the Signalink USB has to be internally wired (by the user)to work with a specific rig and I wanted it to work with 2 rigs! Before even going forward with this adventure I had to open up the Signalink unit and do some long overdue maintenance. The Signalink was purchased used and for some reason the previous owner soldered the jumper wires that configure the unit to work with a specific rig. These jumpers are designed to be plug and play, this way you can reconfigure the unit to other radios if you change your rig over time. The 16 pin IC DIP socket was melted and of no use for what I had planned for it. I set the socket up for my Elecraft k3 and these wires I had to solder in as the socket would not allow the “plug and play” feature due to the previous owner. These wires had to be cut out and then the fun job of removing the 16 pin socket! I have built many kits in the past including 2 Elecraft k2’s. As all kit builders can attest to no matter how careful you are mistakes happen. When the mistake happens of soldering a part in the wrong place……the removal of said part can either go well or very bad! I have had it go both ways and as a kit builder one investment that has saved me many a time is the Hakko 808 de-soldering pump. I used it to remove this 16 pin socket and when finished it looked like nothing had ever been installed on the board. I have tried spring loaded de-soldering pumps and the solder wicks but the Hakko solder pump make all jobs painless. Now with the new 16 pin socket soldered in it’s time to look into making the Signalink work with 2 radio…………coming up in my next post “ how I made this happen and it’s working very well”
After the Hakko 808 is done

Virtual ham radio…sounds interesting!

For the past few weeks I have been up and down the bands in the evening hours looking for some CW activity and with the current conditions signals have been few and fare between. This has forced me to get a firm handle on the digi modes and to be more specific JT-65 and JT-9. As the saying goes "if you don't use it you loose it" and this is my concern due to the lack of CW activity I have been involved in lately, I have worked to dare hard getting my CW speed up to just see it drop off due to lack of activity. Last evening this got me thinking.....what about the internet there must be some interactive over broad band CW happening out there?? In my travels I came across two programs neither are free but they offer CW (and SSB) operating over the internet. Not really ham radio as such but it helps my CW skill stay sharp until the band slump is over. The first program I came across was QsoNet based out of Canada the cost is a modest 40.00 per year and you are given a free 30 day trial which is great. I looked the website over and found the their discussion forum, the last posting was from 2012 and the latest update was back in 2011. This made me wonder if I was just going to be listening to empty broadband due to the fact no one was around. I also wondered if there was active support for the site as well. I then moved on to another site called Hamsphere base out of Europe. This program was 30 EU per year along with a free trial but I was not able to locate for how long. This site seemed to be very up to date and a new version 4 had come out that looked very professional. Their forum was very up to date with postings from 2016 so it seemed like things were alive and well. Hamsphere seemed to be a very in-depth program with such things as a virtual Ionosphere, DX alert system, awards, contesting, multiple antennas to choose from, you can use your own keyer and DX cluster.....and the list goes on! I checked out some online YouTube videos of the program and WOW it sure is a professional program. I was watching one video when the commentator said "these are the antenna selections I have PURCHASED" I thought.....wait a minute what did I just hear and sure enough that's what was said "PURCHASED". I investigated this and found Hamsphere shop and this was the show stopper for me. It seems the 30 EU per year is not the only cost, at this site you can purchase antennas were the price goes as high as 90 EU!! Check out the link and it seems that there is lots of items for the radio that need to be purchased. I was not able to find anywhere on the home page information about extra purchases. It did say you could build your own rig and that there were a 100 antennas to choose from but again nothing about added cost. Another odd thing was you were never asked for your radio license. At QsoNet you had to fax in a photo copy of your license, it seemed not so with Hamsphere. Has anyone out there used either of these programs?? Do you know of any other interactive CW over the internet programs out there??

Multi tasking at the rig.

Reading blogs and operating JT65-HF
I flipped the switch on the radio this afternoon to 20m CW and it was dead! There were some very faint stations basically at the noise level and to hear them I had to engage the Audio Peak Filter. Thinking it was DX calling CQ I was very surprised to hear both calls were from the States! That kinda gave me an idea of the band conditions for CW and I then moved onto JT65 HF on 20m and it was nice to hear many op's. Most of the calls on the waterfall were from the U.S and that's just fine considering the propagation, I did see one station from Spain being decoded. I did make contact with KB0PPQ in Kansas City and while waiting to make another contact I was reading PE4BAS Bas's blog.  Have radio and multi tasking!

An afternoon with JT-65HF

The morning today was full of chores that had to be done so it was up early and go go go. That plan worked out just fine and it allow me to have some time at the radio. I listened for a bit on the CW portion of 20m and it was very slow. I then decided to stay on 20m but move onto JT-65HF and see what was happening there. Right off the bat I decoded ZS6C from South Africa I was not able to connect up with him after several tries he seem to fade off the waterfall. That sure would had been a nice contact but on the positive side I have seen him on the waterfall many times in the past so there will be more opportunities.  I did have lots of  U.S stations calling CQ as well but I was not able to make contact with any of them either day......just not my day on the waterfall. I then changed it up and moved to calling CQ...oh and this post was being written while I was operating JT-65HF you just have to keep an eye on the waterfall and the decoded message. It is going to take a while for me to get the hang of the timing down. When you call someone on the waterfall there is not much time during decode to see if they are coming back to you, coming back to someone else or calling CQ. I did have KA4HOT come back to me but we were not able to complete the QSO most likely because I'm still getting the hang of the QSO rhythm.

UTC time on the desktop

My new UTC clock on the PC desktop
I have Friday off today and got my running around out of the way this morning, so I decided to flip the radio switch and see what was happening. I was going from band to band around 1600 UTC and there was just stations here and there most U.S stations. Then at 1700 UTC I was listening on 20m and on the Elecraft P3 the lower end of 20m came alive! From only hearing U.S stations to hearing LOTS of  European stations and at first I could not tell if it was a contest or not but it had to be.  I went to WA7BNM contest site and looked things over to see what contest it was while at the same time listening to the contest to see what the exchange was. To be honest I did not have to much luck with either, I really could not make out the exchanges and the web site was not really clear what contest this could had been. As I was attempting to ferret out the contest an old issue came back to me....UTC time! I have an app on my Iphone that gives local and UTC time but more often than not the Iphone is not close by when I need to reference UTC time. The same issue comes up when logging a contact on paper temporally until logging it on the PC. I was going to purchase the MFJ 108B dual LED clock but it was good I held off. It occurred to me to get online and search for something that was a free download on the internet!! I found a neat little program that sits on your desktop. You can resize it, move it around, when you restart your PC it comes alive in the last place it was left when you turned your PC off and best of all it's free!  Have a look at it and see what you think and by all means if you are using another program let me know what it is and I will check it out.
