Configuration, RRC 1258 / Help with mode 6 ? Microham
« on: 2016-05-08, 11:39:01 »

I have for years used with success Elecratft K3 and freeware HRD with mode 4 on COM0/COM2(logically parallel) and COM1 (mode 3) for transparent serial traffic for microham stack switch. Also OK as com 1 inactive. Latest SW in RRC, K3 and SMD.

Now I want to add microham box at radio side, and have CAT copy to it: tried K3 on radio side back RS232 (like before), but mode 6, to have  on radio side front RS232 (COM1) microham SMD, to it's cat plug. It works for a while, radio and SMD are communicating OK, but HRD at control side drops off after about 15 seconds, and needs to be started again, same result, halts quickly.

Original RS232 cable between RRC Radio- K3, on the back of RRC (COM 2). SMD was connected to the front.
What parameters should I have:

COM 0         Radio side program mode 4 ?
COM 1         inactive, 4 or 6 ?    (tried all, didn't work reliable)
COM 2         logically parallel with com 0 ?

COM 0         Radio side program mode 4 ?
COM 1         6 (what is mode 11, not documented in the manual ?)
COM 2         logically parallel with com 0 ?

Do I need to swap com1 com2 cables at radio side ? in the settings menu (6) it's always com2 no com1 ?

Is this a too much polling issue in K3/hrd / microham ?
Or have I configured rrc boxed wrongly ?

I had double mobile at radio side, when testing, both rrc boxes had separate routers and different mobile providers.
HRD worked OK when COM 1 was inactive, and I think "copying" rig CAT to SMD locally at remote site should not add much traffic to mobile internet.

I temporarily use double mobile; 4G on control side, and 3G permanently on radio side.
I sometimes experience that I don't get through SSB pile-ups, but if I restart my K3 tranceiver, I get
through. Maybe this forces a better channel through the network.

Does RRC block SSB TX audio if the connection gets lousy *.
Or am I just transmitting QRM on those occasions ? I don't experience this "issue" on CW.
Can this be monitored on the status page somehow ?

Or is my K3 not working properly ?

*  Each Mobile connection might jump up to about 180 ms latency.
Normally they are <30ms (4G) and <80ms (3G). I have however managed to work
a few hundred qsos with this double mobile system.

General discussion / RRC micro on stereo ?
« on: 2012-11-21, 17:31:27 »
Does the dongle work in stereo mode ?
I use traditional RRC 1258s with dual RX activated, can I operate it with RRC micro ?

Joni OH2FT


Maybe this is hidden somewhere in the manuals but...
I have been operating 1000+ QSOs with the internal keyer, but always as pressing simultanously hand mike PTT.
Now tried with wintest, USB DTR as CW and RTS as PTT. Once the message starts it locks itself and never releases,
until I close wintest. By disabling RTS signal from wintest, it transmits CW OK from Wintest on the air, but I again need to push PTT manually. Any Ideas ?

I'm using Elecraft K3 >-< HRD as RS232 on COM 0/2 and a microham box on RS232 COM 1

SW 2.46 setup mgr 1.12

Control side:
USB is NOT used as COM 1,2,3
IN0 mode  I/O   
OUT0 mode  I/O
OUT1 mode  I/O
OUT2 mode  I/O 

Radio side
PTT activated keyer NO
OUT0 mode I/O
OUT1 mode I/O
OUT2 mode Keyer

I would need a solution to select with remote relays
various antennas (4 sq directions, 6 directions from a triagle etc, 8 directions, but haven't found a solution on the market.

Velleman has some pieces, but requires USB connection or a PC at radio end. I would like to have a web-like page that I can modify myself, from which I could select with mouse the wanted antenna directions, and the outputs would use relays in binary way for various selections. Microbit's web switch is not suitable, you can not change state of several relays with one click, nor are the commands published for modifications. Microham's remote stack switch works fine (RS232) with some limited configurations. And yes, you could do your own with arduino, parallax etc, but that would be quite a project. RRC's own three I/Os are fine, but I would need maybe 30 outputs.  I can not be the only one with the need for too many control signals.

Any ideas ? Joni OH2FT

General discussion forum / 2 uplinks with one router
« on: 2011-01-05, 09:29:21 »

Slightly off the topic, but anyone here who has put two internet uplinks on the same router,
with ip-address based load sharing, and using it with RRC (radio side). The aim is to utilize the latency wise better ISP for RRC, and route web switch, serial webserver for rotor control, and other not so critical services to a low cost ISP (mobile 3G). My 3G unfortunately has some blocked ports for incoming signals, so I hope those could be bypassed by using the other ISP line for input, and sending answers back on the low cost. So having separate routers per ISP doesn't solve the problem with this particular 3G provider. And in any case,
at least I would gain some redundancy and extra band width.

There are double wan port routers on the market, but before spending some 300EUR,
maybe someone has done it already ?

PS I'm very satisfied with my RRC, using only one ISP (450 MHz OFDM system).
