After playing around with the MD-380 program and entering frequencies, I decided to investigate the Contacts section of the program. Unlike D-Star which shows you the user callsign when receiving a transmission, DMR only shows you the 7 digit “subscriber ID or call ID” number which is supplied by the http://www.dmr-marc.net/ folks when you sign up for an ID. There is a database query on the dmr-marc site where you retrieve someones ID by either name or callsign. You would then enter this information in the Digital Contacts section (think of it as an Address Book) of the CPS MD_380 Program. The contact section also contains (probably at the top) the talkgroup information of the repeater or regional network that you want to connect/talk to.
There is another alternative to obtaining user ID’s by the FoxHollow folks [LINK]. There is a daily download available from the site that contains all the ID’s on a daily basis. Here is a direct link for the daily contact zip file.
If you wish to bulk import to your MD-380 using a program like the one N0GSG , Tom Wheeler, provides , the daily zip file contains two folders called CS700 & CS750 for the Connect Systems portable radios. The instructions will tell you that the files that you need are in the CS700 folder which are .csv files. However, they are missing two columns that prevent you from importing. In addition to the provided column data called ID, Callsign & Name, you also need a column for Group Call (or private call) and Alert tone. This can be accomplished by opening the file with Excel and creating two new columns for that data.
You can also manipulate the files in the CS750 folder which are Excel XLSX file. These are alittle more complete but the column data is positioned incorrectly. You can moved the columns around to be in the ID, CALL/Name, Group, Alert format then save the file as a comma separated file (.csv). I can make a short video of the two ways to convert the data for import if there is any interest. Drop me an email to firstname.lastname@example.org if you would like to see this
Digital Mobile Radio (DMR/MotoTURBO) has come to Tallahassee. Norm, K4GFD, has added a Motorola SLR5700 to a downtown site on 443.1375. For as little as $130, you can also join the fun by acquiring a Tytera MD-380 portable radio pictured below. Click on the picture for a blown up look:
The screen is really clear. For some reason, the camera put little lines through it. If you would like to know more about the DMR network, drop me a note (email@example.com).
If you are into digital modes, you have no doubt have heard about the Texas Instruments chip issue (which they have acknowledged) that was brought to light by Jon, KD9DAL, that affects amateur radio digital modes using the Signalink or built in USB “soundcard” in various ICOM, Kenwood and Yaesu radios and interfaces. Here is the video that explains what the bug is and how to fix it:
Click Here to go to K3RRR’s site with the updated text (and a 15 point checkup) to go along with the new video. Here is the original findings by Jon, KD9DAL.
I’ll have the files posted shortly that are mentioned in the video (oscilloscope & level meter).
Got a note from my provider (fatcow.com). “When we conducted a routine scan for your account ‘XXXXXXXX’, we found the malicious or infected files. We have uploaded a file named ‘list.txt’ within the stats directory of your account which contains the full list of files.”
179 to be exact. Most were old original files from my earlier WordPress installation, old dates. Not sure why the scan took until now to pick them up. Others were newer files but they all had the same “type” filename. So when you go deleting files like “function.php” and other types in WordPress etc., you tend to have a non-working site after it was all “said and done”.
Going to change the theme when I decide which one.
Well 2015 Field Day is approaching and I’m the captain of the digital station. My personal HF station has been down for about 6 months now due to antenna issues and me not able to climb my tower to fix those issues. Well I did manage to climb on Sunday as black clouds where looming south of my QTH as a thunderstorm was heading my way. I pulled the Icom AH-4 down from the 45 foot mark down to the ground so I can get a look at it and see what’s wrong. Was going to put up my Cobra Senior but it seems that my ropes and pullys in the pine trees have some issues… like me not being able to lower the AH-4 wires down and pull the Cobra Senior up. Weather turned to crap shortly after I brought the AH-4 down so the Senior install will be another day (maybe today!)
Once the antenna is up, I plan on trying out my new toy… IC-7200 Camo Edition. Don’t know why but I’ve had a thing for this rig ever since I saw the first one down in Orlando at Hamcation. Gigaparts is the only supplier that has the painted versions available and only those are available now for some reason. Do a search for IC-7200 and all major suppliers are out of stock. Supposed to be a “parts supply shortage”. Who the heck knows…
This is a good rig for digital ops which I mainly operate so I’m going to be testing it out before Field Day. Have to get use to not having to hookup a Signalink USB device like I use on my IC-756ProIII and IC-718. Now that I have this rig, I’m going to have to cull out some of my Icom stock. Currently I have 2 IC-718 rigs, IC-746Pro, IC-758ProIII, IC-703 QRP rig and an ICOM M-710 marine rig for Amateur use.
I will have to say that I have ordered quite a few things in the past few weeks and I have nothing to say but good things about ordering on-line from both GigaParts and HRO. All the orders were at my doorstep within two days of my order and both provided updates via email. Nice to do business with those folks!
There is a group of folks (most are non amateur radio operators) who have taken to experiment with beacons on 22 meters (around 13.560 Mhz). This is an unlicensed area of the bands that the FCC allows you to experiment with different modes (QRSS, WSPR etc.), transmitters etc. It’s only authorized for extremely QRP power… we are talking about 5mw or so. There are 3 or so bands for this kind of experimentation and the bands are commonly referred as LowFer, MedFer and Hifer depending on what part of the HF spectrum band you are operating. You can go to my other site, 22meters.com to see the actual Part 15 rules. I just started the page so there is only one page at the moment. I’ll have more to post shortly.
Currently I’m building my “HiFer” station. I’m using an Icom IC-703 as the transmitter and currently building an attenuator to bring the power level down to less than 10mw. Starting off I’ll be using WSPR since this mode is an excellent QRP mode. I’ll be feeding this to a dipole about 34 1/2 feet in total length, around 40 feet up. Still deciding on how to feed it, ladder line or coax. Will be interesting to see exactly how much power will radiate.
