Hi Webswitch forum,

has anybody else faced need to control NEXA switches on HAM firmware version?

1.) it would be great to have few NEXA controls available in HAM version, to reboot/reset some remote station devices.

2.) Secondly, im aware of using Webswitch as automatic antenna switch based on Serial comm with radio... but due to many other devices needs serial cat, it would be nice feature if CAT could be connected also same way as in AS1269 per IPaddress. Any chance?

General discussion forum / Newest bootloader files?

from which path i can find latest bootloaders and their history?

I can find latest 4.xx firmwares from below link... but newer than 4.27 needs later than 1.13 bootloader.


Thanks Mitch for checklist

Yes, i did, i have saved settings of each configuration also in text format - that i can check.
I did it via ddns address and went to local LAN via Teamviewer connection and used local IP with given web port.

Maybe there is mistake - as working connection and web server port dont have relation.

thanks anyway!


Thanks Mitch,

i guessed also that latency is the issue, but just wanted check that in that case fast speeding VFO will cause Disconnection in HW/or SW logic of RRC. I guess Latency and bandwidth is varying continously so much that diffucult to see improvement.

Surprisingly i tried to made changes to Radio end unit, but ddns address nor local pc remotely controlled with local IP-address cannot access to configuration pages ...have you ever had similar issue? Connection works well between Radio-control units, but web-interface not.... do this means that i should reboot Radio RRC or any other tricks?

73s and season greetings



I have TWIN with pair of ft5ks... radio site at OH6 and control site at HL1... latency is varying 250-350ms.

While tuning faster bands (meaning 10kHz per sec) then audio starts cutting (like noise, on very short disconnections and fast freq , noticing in audio) and if i keep still tuning fast, total disconnection happens... so that on control end power led goes off and starts blinking and control unit will re-create connection.

Does anybody noticed same behavior? im considering this as connection bandwidth issue?
I have RXbuffer value on 4 and delay on 3 per standard.

It does same with two different Control units, which SW is 2.75 and HW 8.


Status update to Yaesu ft5K Twin setup

FT8 mode seems to be pretty easy to implement, just install WSJT-X program and do required settings. I can share print screens if needed.
1.) Just plug in RRC Audio to PC  Mic and PC output to Mic input of RRC
2.) CAT doesnt seem to work on WSJT-X same as it is working on with N1MM+, this is still under investigation.

has anybody easy instructions for FT8 implementation for Twin-Yaesu setup?


Hello Remoterig-Gang!

Im back in business with my remote-setup, as i have been qrt for over 2 years due to moving cottage station qth to another location in OH6 Finland and having Control qth here in HL1 Seoul. Feels so Great to be back  :)

My Twin setup is based on RRC1258MKIIs and FT5Ks and there is about typically 200-300ms latency - not bad at all, of course VFO control has some delay, but ears, brains and hand will adapt to delay pretty easily.

Im actually returning back to the problem i had back in May2015. Im running log, CAT based on N1MM (now +) and Radios (twin) communication goes via COM2 and CAT of N1MM+ is connected to COM1.

The challenge i have, is related to N1MM+ bandmap frequency behavior... typically its really slow (delayed) and follows actual VFO (Control) very slowly when same time VFO (station) is following per short delay / latency (no problem). Also for time to time the CAT to N1MM+ is getting very unstable, meaning it zig-zags up and down, although VFOs have tuned long time ago to DX freq... and might take 10-20secs to stop... or sometimes not stopping at all. Im using Samsung 9xxx series laptop with ATEN UC232A (Ftdi circuit) USB to serial adapter. Driver is ok per computer.

First of all, does anybody else have similar "symptoms"?
I remember that studied before QRT period that could it be Laptops Switching power supply, which could cause some interference to serial... if i remember correctly, that time it helped for temporary to use with battery only but behavior returned to same soon (so i couldnt prove interference issue).

All ideas for finding root cause are welcome!

Anyway, great to be back to bands - we have here in Seoul city center very bad wide band (1-50MHz) man made QRM so without remoterig, i couldnt be on the bands from HL1-home.

73s and thanks for ideas




R.FLT selection works great 300/600/3k... but  e.g.  VFO A Width control doesnt work on pair of ft5k?



General discussion forum / TWIN Can Yaesu FT5K control FT2K?
« on: 2015-03-01, 06:40:21 »
Hi "Remoters",

In Twin Yaesu, Manual says that ft2k can control ft5k, but how about the other way?



i just want to make update to this matter... that i have not found any solution, although i tried to change to N82 and i also tried to return back to USB-RS232 adapter, but it was even more problematic, as TWIN + ATEN232 caused after some operating time the N1MM go to totally Crazy by jumping it around to different frequencies, bands and modes. This happened on CQ WPX SSB 2014 and recently tried also on Scandinavian Activity Contest 2014 SSB... outcome was same, more problems with USB adapter... so im going to stay on Direct USB CAT link to N1MM.

With Direct USB CAT N1MM to RRC1258, the communication failure message comes "Radio Sent Invalid CAT data", but then the message has to be checked ... i cannot know if its because latency or because long control distance (from HL1 to OH6). I thought for while to find solution, as my Samsung Air N9xxx series laptop power supply creates some noise... too power supply away, i felt that error is coming less... but then after sometime it comes anyway...

All ideas are welcome... i would like to find solution and willing to invest and trial & fail. ;)

Hi Dennis, thanks for comments

i didnt have enough time yesterday to try another laptop and N1MM.

As running Twin, baud rate is 38400N81 and 10ms... on both radios. Also N1MM which is latest Version 14.3.1.
With Direct USB comms to COM1, failure message comes easiest if Radio "sits" on without operation as well as N1MM... this message is cleaned away by changinng band from Radio. I will keep on testing more...

By the way, should TWIN concept controlling "radio station" radio e.g. filter width by setting "remote/control" end radio width?
How about data settings like baud rate? My experience is NOT.

SE0X, ok, i remember this qso... i was in Asia, Seoul City Center, Rep of Korea. ;)

Just for your information...

I have been using now CAT on COM1 for some time, but similar error message is appearing , but not so frequently and behavior is not bad as before... BUT its still existing.

I faced previous configuration real problem, when i operated CQ WPX SSB contest... for some reason N1MM bandmap & CAT control started "throwing" my radio to other frequencies when i kept pileup... also when jogging with VFO... the CAT frequency on N1MM was following slowly and fading... back and further...

Hard to say, from where to start looking for root cause... Radio, RRC, Laptop or N1MM.... last two i can try to block away by taking another laptop with N1MM for use for while...


Sorry bad terminology... I dont have pc connected to radio, on radio site i have linear cat connected to com1.

Remote=control site... As i understand remotely controlled station :) @HL1
Radio= station site with antennad @ OH6

Mode 6 is for COM1!

I will try usb to usb and see how i can solve keying... This reserves extra usb but not a problem

Ps. Seems that this N1MM msg of complaint is somehow related to bandmap scrolling, interrupts, as it is not following

Anyway thanks for your help...


Dear Mitch, Dennis & Gang,

Yesterday i played with settings little bit... i found that COM1 port RTS/CTS has influence to this feature. When i activated  control signasl, i couldnt get this failure msg anymore... although N1MM bandmap got slower or didnt folllowed remote VFO instantly, freq updated only when VFO jogging was stopped. BUT logging window Freq indication followed without delay. I didnt play many hours, but seems that this has influence on my setup. Now Problem is that i want to use RTS for PTT control.

Question/Comment for Mitch: Your idea is to use RRC USB port to Laptop USB port? I have not try this. Im considering to use this USB to Serial port also for PTT and CW keying. Then i use USB to RS only for CW?

Dennis, yes i have Laptop for qsos logging on Remote control side (at HL1 Seoul Korea) and USB to serial connecting laptop to COM1 RRC for CAT and CW keying controls. My Station locates OH6... there Radio RRC is directly connected to ft5k.

Im doing more testing today after work...
