Thanks!

Good to have confirmation that the pot is 10k linear.

I posted a photo of the apparently-failed pot in another post, and have added it here as well.

I have never seen that before

exactly the same as assebled is not easy to find but the tech guys think this one from Mouser will fit

Hardware, Cabling, Installations / Replacement Part: RRC-1258 CW Pot?

« Last post by K8ND on 2025-06-17, 23:08:18 »

The problem I had with adjusting CW speed on my RRC-1258 MkII appears to be a failed potentiometer, which shows physical signs of damage.

It is marked "103A, 437C". See the photo.

Can someone here identify a replacement part?

Hardware, Cabling, Installations / Windows 11 / Setup Manager: Driver Will Not Load 'ftvspenum.sys'

« Last post by K8ND on 2025-06-16, 08:52:13 »

I installed the Microbit Setup Manager software (version 2.06) on my Windows 11 laptop. During the installation, my screen was filled with eight instances of a popup that said:

       "A driver cannot load on this device, Driver: ftvspenum.sys"

The same popup now occurs whenever the laptop is booted.

The Setup Manager seems to work OK, but I am having some issues with the RRC1258 (CW pot not working, IP address not always retained across power cycles).

Anyone else have similar experience with Windows 11 and Setup Manager WRT 'ftvspenum.sys'? Suggestions?

Hardware, Cabling, Installations / CW Pot Not Working?

« Last post by K8ND on 2025-06-15, 16:15:49 »

New installation of a recently-purchased used RRC-1258 MKII box. Cloned the configuration from the remote terminal I've been using for several years. Everything seems to work, but the CW Pot does not change the CW speed. Paddle is plugged into the RRC1258 box, and CW is sent well, but only at a fixed speed.

CW speed seems to be fixed at whatever speed is entered in the 'Speed pot min wpm (5-99)' field of the 'Keyer Setup'. 'Speed pot max' is set to 40 wpm.

If I start N1MM+, it initially correctly shows the speed currently configured as the minimum wpm (and being sent by paddle), but it does not affect the actual speed of the keyer when adjusted up or down.

From the 'Info' panel:
HW   8
Software   2.95
Bootloader   1.10
Compiler   4.6.2

General discussion forum / Receiver box shuts down unexpectedly

« Last post by Jaume on 2025-06-13, 12:50:48 »

Good morning,
I've had the equipment for two months now, and quite often—some days more than others—the receiver box shuts down unexpectedly, I mean Icom 7100. I reconnect, and it connects again without any issue. It feels like there are micro dropouts.
I've tried different internet connections on the radio side, but the issue still happens.
What could be going on?
Thanks for your replies.

General discussion forum / Re: Modes 6 & 7 (CAT to COM2) doesn't support all CAT commands?

« Last post by lb1ti on 2025-06-11, 17:27:01 »

The split functions not working _could_ in theory be because if I as a consumer of COM2 (on the control side / client side) ask for IF; it will pipe this command over to COM1 where COM1 will receive the `IF` command response, but this isn't routed to COM2 in my experience.

I have a setup which uses the same settings and configuration as you although at a higher baud rate. My "twin" TS-590SG is just a ESP32 but it accomplishes the same thing.

In order to reliably detect whether or not the radio is in split mode the IF command really is the only way; at least that's my experience with the protocol.
I don't know why this is the way it is but I plan on creating my own COM0 to connect on the server / radio side to see if that helps.

I realize that the "muxing" of the CAT data is a difficult thing to do well, it's a complicated thing to be able to serve different endpoints with the same data.

General discussion forum / Control RRC restarting

« Last post by SA0IAT on 2025-06-10, 09:06:32 »

I have a Yaesu Twin setup (FT-2000) since many years. From the start I have an annoying problem, which I haven't been able to fix.
The problem is that the control side RRC-1258 is restarting from time to time. It's especially bad when this happens in the middle of a QSO (even more while working a most wanted DX or in the midst of a contest). I have tried to troubleshoot this over the years, but I have totally run out if ideas what more to try. It's very possible that I have overseen an obvious setting or possible cause. So please help me with ideas and thoughts, TNX!

Configuration facts:
RRC-1258 control side, fw version 2,95 * Bootloader 1.14 * compiler 4.6.2 (however the problem was the same with different versions too)
Connected to original power supply (but problem was the same, running on my "big" 13,8V power supply in the shack)
Connected to FT-2000 with CAT cable supplied with the Yaesu Twin Remoterig kit
Connected to computer with 2pcs RS232 serial cables (but problem is the same without these connected)
Connected to LAN (via router and swicth. However the problem was the same connecting directly to 4G router, and Ubiquiti wireless link as well)
Connected to speaker amplifier

What I know so far:

+ The problem is erratic. Sometimes it works flawlessy for 10 hours. Sometimes it restarts twice in 5 minutes
+ At times instead of restarting, it totally freezes the radio controls and a humming noise or high pitch tone is sounding in the speaker audio
+ The problem happens regardless if the radio is on or off (just powered on the RRC-1258). However radio still connected to the RRC 1258.
+ Problem was the same in 2 different QTH's
+ Problem is the same with original power supply and other power supplies
+ I replaced to PCB in the RRC 1258, no change
+ I replaced the entire RRC 1258 with a new unit, no change
+ I have tried different internet connections, no change
+ I measure 0,000V on RRC-1258 ground to common ground in my shack

As said, any further ideas are highly appreciated!
