Configuration, RRC 1258 / Re: Virtual ports won't install under Windows 10

« on: 2018-04-28, 16:34:46 »

Hi Mitch,

I followed the instructions. The report on notepad was not too informative since there were no RRC ports to remove.

I uninstalled Microbit programs and drivers, rebooted, and re-installed. Same problem.

I'm not ready to nuke all serial ports. There are 5 pre-installed ports that came with the PC and I don't know if I have the capability of re-installing them if I nuke them. I'm not ready to take that risk.

I don't see how there can be a numbering conflict. Wouldn't the virtual ports just install at the next available number?

Other ideas are welcome.

Configuration, RRC 1258 / Virtual ports won't install under Windows 10

« on: 2018-04-28, 13:11:12 »

I've been successfully using my RRC-1258 with RHR for 2 years running CW, SSB, and FSK RTTY. I upgraded to a new PC running Windows 10. The Microbit installer does not install the virtual ports which means that I don't have access to COMExtra for running FSK RTTY.

I've uninstalled and re-installed the program numerous times. I've tried running the installer as an administrator. The installer version is 1.31_2016-03-10. During the installation I see the pop-up that I may have to approve the installation of the virtual ports. I also see a message that the virtual ports are being installed. I don't get any additional pop-ups asking me for any approvals. After installation there are no virtual ports in my PC Device Manager window.

Viewing my PC Device Manager I chose an action to Add Legacy Hardware. Manually searching led me to find all 4 virtual ports with proper COM numbers. I manually installed each of them, however, they all showed up in Device Manager with a warning icon. I tried to use the ComExtra port from within N1MM/MMTTY but it was not workable. I tried the COM port number, EXTFSK, and EXTFSK64. The MMTTY message was always "Can't Open COMxx".

Any ideas?

Hi Frank and Ziv,

Mix 31 seems to be a new favorite. See the article by K9YC. Here's the link and a text snip.

http://audiosystemsgroup.com/RFI-Ham.pdf

New #31 Material is a Problem Solver
  The relatively new #31 material made by Fair-Rite Products is extremely useful, especially
if some component of your problem is below 5 MHz.  Measured data for the new material is displayed in Figs 18a and 18b. Compare it with Figs 19a and 19b, which are corresponding plots for the older #43 material. By comparison, #31 provides nearly 7 dB greater choking impedance at 2 MHz, and at least 3 dB more on 80 meters. At 10 MHz and above, the two materials are nearly equivalent, with #43 being about 1 dB better. If your goal is suppression or a feedline choke (a so-called current balun), the #31 material is the best all round
performer to cover all HF bands, and is clearly the weapon of choice at 5 MHz and below. Be-tween 5 MHz and 20 MHz, #43 has a slight edge (about 1 dB), and above 20 MHz they're equiva-lent.  We'll discuss baluns in detail in Chapter 6.  The new #31 material is useful because it exhibits both of the resonances in our equivalent circuit – that is, the dimensional resonance of the core, and the resonance of the choke with the lossy permeability of the core material. Below 10 MHz, these two resonances combine (in much the manner of a stagger-tuned IF) to  provide significantly greater suppression bandwidth (roughly one octave, or one additional harmonically related ham band). The result is that a single choke on #31 can be made to provide very good suppression over about 8:1 frequency span, as compared to 4:1 for #43.  As we will learn later, #31 also has somewhat better temperature characteristics at HF.

Configuration, RRC 1258 / Re: N1MM+ New User Help

« on: 2015-11-14, 12:01:06 »

Hi Fred,

Also a newbie here using a K3 to communicate with RHR. My intermittent communication problems at the control end were resolved by changing the baud rate on N1MM to 9600. Also change the baud rate on your PC for COM 15 to 9600 using your PC device manager. And a corresponding change to the baud rate on the RRC serial setting screen.

Hardware, Cabling, Installations / Splitting & controlling SP output

« on: 2015-09-10, 20:00:49 »

I wanted to split the speaker output of the control RRC between headphones, speakers, and a line input to my PC (for RTTY). A straight splitter cable was one solution but the simple speakers I was using didn't have a volume control and I had difficulty balancing the speaker volume and the line input for RTTY. A simple solution was the Behringer HA400. It is technically a headphone amp with 4 outputs and 4 volume controls. It is roughly 4" wide by 2" deep and 1" high and sits nicely on top of the RRC-1258. Here's a link:

Thank you. You are correct. I took out my larger magnifying glass and I can now see that the jumper I was questioning is actually JMP5. There is no JMP4.

Hardware, Cabling, Installations / Jumper 4 Clarification

« on: 2015-09-02, 13:34:52 »

I'm setting the jumpers on the control RRC and I'm a bit confused by the manual text and illustration on page 24. I want to set up the SP output for headphones. So should the jumper be in place or should it be removed. The illustration suggests that there might be 3 pins. My unit has 2 pins. My RRC model number is RRC-1258MKIIs V7.
