Station Master


Port A – Antennaswitch (DB25F)
Each Station Master has it’s own cable to the Double ten switch and inside the switch connected each to one it’s own “side” of connectors. The antenna switch requires 12V to select an antenna (common ground). Controlled by Port A – configured as voltage sourcing using internal power (default INT/SRC jumpers). (outputs A1-A10). Outputs A6-A10 are not used (yet). Cabling the Double-Ten switch to both Sttaion Master can be found at the bottom of this document.Nr 14 – Port B – bandpassfilter, sequencer (DB25F) ICE-419A BPFBand Pass filters (ICE419) requires switch closure to ground.

For proper BPF operation the PORT B jumpers must be set to INT/SNK(outputs B1-B6). This is not the default and should be changed inside the Station Master.
Outputs B7-B10 are not used (yet).Nr 5 – Port PA – Power Amplifier (DB15F)Tentec Titan: Has both a KEY IN (=PTT) and a KEY OUT (inhibit for QSK). Using the Key OUT has to be enabled in the Station Master PA & Sequencer Tab (INH).

Heathkit SB-220: Only has a PTT connector so only pin7 used from the Station Master. No inhibit signal used. Nr 13 – Port ROTOR – Antenna Rotator (DB15F)Maybe one day.StationMaster cablingMake sure you used the correct connections: pin 7 for “key out” (to the Key in or PTT jack of the Acom), pin 6 for “key in” (from the “key out” or “amp ready” jack on the Acom) and pins 13/14/15 for ground (shield of the two control lines). Relays used in Station Master are: TOWRD N4100HS3DC12V 3A/125VAC/30VDC

DOUBLE TEN Port lockout with Station Masters

Solution 1 by Josef – OM7ZZ
For this soution to work the outputs with both contact poles avaliable (B7, B8, B9, B10) should not be used.

  • Output from left SM port A1 connect also to B7-NO on righ SM.
  • Output from left SM port A2 connect also to B8-NO on righ SM.
  • Connect both B7-COM and B8-COM of right SM together and thru 1Kohm resistor to GND. Node point connect to KEYIN input of right SM (KEYIN, PA pin6).
  • Do same from oposite side of view for left SM.Configure both SM to activate:
  • B7 together with A1
  • B8 together with A2
  • on PA & Sequencer tab check “Use Key In”This way, KeyIn input locks TX on MK2R (thru iLink) if has high level on input.

Normaly gets GND thru 1 kohm resistor (TX enabled). When left SM activates A1, also activates B7 to which other pole is connected A1 from right SM. So far so good, other pole of B7 is floating, but when you switch A1 on right SM, right SM puts 12V on A1 which pass thru closed left B7 to its Keyin. Same right SM closes its B7 which is connected to A1 of left SM from where gets 12V to its Keyin. Result will be that if you select same antenna port on both SM, both radios will be locked. Same for second port (B2+B8), hope OK for you.If you use (have connected) PA with KeyIn (Acom, Alpha etc …), do not ground end of 1Kohm resistor, but connect it to amplifier’s KEYOUT, it will be grounded thru PA. Alternative solution
It is also possible to connect nodes with 1Kohm resistors to ACC port inputs on MK2R configured as INHIBIT inputs instead of SM Keyin, but in this case there must be serial resistors and 5V zeners to not pass 12V to MK2R ACC’s TTL inputs. It will provides equivalent functionality.

Solution 2 by Joe – W4TVThe schematic above represents a partial schematic (only antennas 1 and 2) and not that the “Inhibit” connections are to “Key In” on the PA port.The intent is to avoid using B7-B10 and to lockout transmit only on the ‘second’ radio. Remember only the application software can prevent selecting an already used antenna port – this simply prevents transmitting into an open feedline.Using the situation of triband antennas on ports 1 and 2, the above circuit will prevent transmitting into an open port. There is nothing that will prevent one radio from selecting a port that is already in use by the other radio. The diagram above will prevent transmitting with no antenna connected.The transmit lockout uses an idea from Jozef (solution 1 above) (the Inhibit or Key In line) but uses a pair of external 12V DPDT relays to do the switching … in this case, if one radio has selected a port that is “in use” it will be inhibited but it will not prevent the original radio from transmitting (e.g., run radio is on 20 meters using the tribander and the S&P radio selects the tribander on 15 meters the run radio continues to work because it was the first one there). This is a “first one wins” lockout. There is no need for a “double” lockout – that is handled automatically by MK2R if both radios are put on the same band.Radio settingsProposed settings by microHAM:The TS2000 will transmit audio from the mic connector when PTT via Command PTT (This is the same as PTT using pin 13 of the ACC jack).Our choice is to use FSK using pin 11 of the ACC jack the TS-2000 needs PTT on pin 9 (PKS) to enable audio from pin 11 (PKD) and mute the microphone jack.
W4TV believes there may be an undocumented command (TX2;) that will put the TS-2000 into transmit with PKD enabled but I’m not sure.
When using the ACC jack configure to raise RTS to transmit and configure Router to use PTT_2 (PKS). That will allow BBB to work properly.

microHAM Router setup

Tab: Ports MK2R-Tab-Ports-PA1M.jpg

  • Radio: Assign Radio 1 to COM4 and Radio 2 to COM5
    • Click the Setbutton for each radio and select the radio on that port from the drop down box
      • Do not check the “Disable router queries” box (so empty them). With that checked, Router no longer polls the radio and the internal flow control does not allow data to flow properly from the logger to the radio.
      • PA1T: Check the “Forward autoinformation to CAT port” boxes with an Icom radio.
    • Test: Check the radio by turning the VFO, frequency in uRouter should follow frequency radio.

Radio 1 – Elecraft K3

Radio 2 – Kenwood TS2000

  • FSK: Assign ports for FSK. DI-1 to COM6 and DI-2 to COM7 and uncheckthe PTT box.
    • NB. If you are not using N1MM Logger for RTTY contesting you can skip this step.
    • If you are using the same port for PTT and FSK, uncheck the PTT box next to FSK.
    • Further down set PTT to the same port as FSK and select RTS.
    • Test: Test buttons sends FSK (MK2R: PTT: green; CW/FSK blinks green)
    • NB Don;t forget to set up the radio for FSK (K3 Select long DATA MD for FSK D per Band!!)
  • 2nd FSK: Not used
  • CW: Not used
  • PTT: Assign PTT Radio 1 to COM6 and PTT Radio 2 to COM7 and select RTS for both ports.
  • 2nd PTT: Not used
  • Foot switch: Not used. Is output port to software, not supported by N1MM logger.
  • Winkeyer 2: Assign COM3. Check Generate PTT1 on the CW/WinKey tab if you do not intend to operate QSK.
    • Test: Test buttons sends test in CW on radio 1 (MK2R: PTT: green; CW/FSK red in CW rhythm)
  • Control: Assign COM 8

Tab: Audio SwitchingIf you do not intend to use N1MM DVK, use ACmA.

Radio 1:
Voice/Digital for the K3 should be “Use VOICE settings” since the K3 has a separate digital mode that supports AFSK (AFSK A or DATA A).
Use line out channel: Left

Radio 2:
MK2R-Tab-AudioSwitching-Radio2.jpgVoice/Digital for the TS-2000 should use “Select by frequency” since Kenwood does not support an AFSK mode.
Use line out channel: Right

Tab: Audio Mixer
Rules for audio playback are: Click on “get ID” in router’s audio mixer tab. Make sure that WAVE IN ID == WAVE OUT ID == MIXER ID. The N1MM Logger audio control cannot handle the situation where the Wave ID <> Mixer ID – it will send (or record as the case may be) audio from the wrong sound card. If the Wave and Mixer IDs are not the same,set the MicroHAM CODEC as the windows “default” sound card and configure N1MM Logger to use the default device.The soundcard name displayed in the audio mixer selection box (left half of the Mixer tab in MK2R/MK2R+) must match that shown in “Get ID” and the “Select Device” selection box in the N1MM Logger Audio tab.MK2R-Tab-AudioMixer.jpgTab: PTT
For CW/VOICE select PTT1 (microphone jack) and for FSK/DIGITAL PTT2 (rear panel jack).
If you are using QSK in CW select QSK for CW.PTT Lead is the amount the transceiver PTT is delayed with respect to the PA PTT and should be about the same as the INH time in Station Master.
PTT Tail applies only to WinKey (it is the “hold” time between elements).NB The K3 has only one PTT (Mic, rear panel and ACC are all the same line) so PTT1 (mic cable) and PTT2 (ACC plug) are the same to the K3.MK2R-Tab-PTT.jpgTab: CW/Winkey

Tab: Keyboard
MK2R-Tab-Keyboard.jpgTab: SO2R
Select microHAM control protocol on COM port (NB com port is set on Ports tab) and 1 footswitch for both radios.TX logic: First one wins … is the correct logic for SO2R. It prevents transmission from starting on the second radio if the first radio is already transmitting.
These settings allow N1MM Logger to fully control both transmit and receive selection automatically. Stereo receive is commanded by the “`” (backquote or unshifted tilde key) or the {STEREOON} and {STEREOOFF} macros.MK2R-Tab-SO2R-PA1M.jpgTab: ACCMK2R-Tab-ACC-PA1M.jpgSelect “Controlled by microHAM control protocol“ in the two drop-down boxes. Pins 6-9 and 10-13 are connected to two banddecoders which drive the microHAM 2by10 SO2R switch. Note that these precisely pass through the antenna selections from the N1MM Logger Antenna tab – so you can have multiple antennas on a given band, selectable from the keyboard.

Tab: Functions MK2R-Tab-Functions.jpgBy Joe, W4TV: Using the “Functions” tab in Router, create the desired audio switching pattern. Check the Auto boxes for Transmit Focus, and Headphone Switching as well as Latch and Monitor. From what you describe it would look something like this:
RX on R1 X X
RX on R2 X X
C on R1 X X
C on R2 X X
TX on R1 X X
TX on R2 X X
<FIXED>Select a “Function” memory to store this configuration and click the “Store” button to write it to the MK2R. Then click the “Apply” button to make that function active or press the F # button on the MK2R front panel.
If you need to monitor sidetone when manually transmitting – e.g. to hear sidetone in CW, the Headphone settings would look something like this:LEFT RIGHT
RX on R1 X X
RX on R2 X X
C on R1 X X
C on R2 X X
TX on R1 X X
TX on R2 X X
<FIXED>Remember the “functions” tab is simply a graphical “matrix” editor. Anything you can create must be stored to a Function memory and recalled or applied to activate.The “computer on R1/R2” options are only available if “Latch” is selected. The “TX on R1/R2” options are only available if “Monitor” is selected. The Stereo selections are an “override” that is applied only if the logging program issues a “Stereo” directive (e.g., LPT pin 9 in NA or the “Stereo” command from a program that supports the microHAM protocol). The “Fixed” settings are used only if the Auto box is not checked for Headphone Switching (the other seven lines are ignored).

By Pete, N4ZR: I wanted to be able to use N1MM’s FocusOther function to control where the entry focus was when I was transmitting on one radio or the other. The greyed-out options for “Computer TX on R1 and R2” get in the way of that. If you uncheck “Latch” in the Headphone Switching area, that disables those choices and lets N1MM be the boss.
Manual TX on R1/2: the ability to listen to sidetone when sending paddle CW = to hear sidetone in both ears when sending manually.

Saving you work
Save settings to a preset by selecting menu Preset | Save as. Choose a position and name it (example): N1MM-all modes.Note: Each of the tabs is complex enough to warrant careful attention. Incidentally, it is always a good idea to save your last working setup as a Preset, so that you can retrieve the situation if you mess up. It also makes sense to save your experiments.
It is needed to leave router running as it’s the spider in the web for our SO2R setup.

N1MM logger setup

There’s nothing magical about which ports are used for which purposes; you just have to be consistent between N1MM Logger and the MicroHam Router.

  • Click Config| Configure Ports, Telnet Addresses, Other …
  • Hardware Tab

It is not necessary to check CW/Other on the “Digital” ports. PTT will function even if “Other” is not checked.
COM3 to COM7 – set any unused handshake line (e.g., DTR) “Always Off” to prevent unwanted transmission if something is not configured correctly.
On the Digital Ports (com 6 and com 7) RTS or DTR must be not be set to “Always On” (otherwise PTT could come on when starting the program).

  • Digital Modes Tab
    • Select Soundcard as the TU Type
    • Select FSK as the mode.
    • Enter the path to each MMTTY installation.


  • Winkey Tab
    • Use 2nd Output should be checked. This allows normal switching of WinKey2 output.
    • Pin 5 Function should be PTT (unless you are using QSK)

      • Sample Rate: 11025
      • Radio Input Port: <blank>Radio Input Port should be blank!
        • If not blank, select another ‘Select Device’ and switch back to the USB Voice CODEC. Now it is blank.
    • Max Recording Length (secs): 30
    • Recoridng channels: 2 (although Joe says 1)

NB.Leave TX Soundcard set for “USB Voice CODEC” with Input Line set to Microphone and Line to Mute set to anythingEXCEPT WAVE.Do not mute Wave!! and do not select the option with 2 soundcards (5$ So2R).It is not necessary to change CODEC when running Digital modes. The N1MM Logger “Audio” tab only effects the DVK sound card. The RX soundcard settings are used only if you have selected “Dual Cards – Two Radio, Sound Card SO2R” (= $5 SO2R).
All of the sound card selection for Digital operation happens in N2AMG’s Digital Interface code. It is through the DI that one selects the soundcard to use for MMTTY and/or MMVARI.

Filter setup (bandmap button)
Right click in bandmap and select “Set transceiver filter codes”. Make a choice:
The kenwood settings are the default in N1MM logger.
The K3 has te be set up using K31;FWxxxx;K30; where “xxxx” is the desired bandwidth divided by 10.

Function keys
Not only messages can be placed into Function keys but also commands can be sent to the radio using macros.
Example: {CAT1ASC cmd } or {CAT1HEX cmd } The number 1 is the Radio which can be 1 or 2. Cmd is the command to the radio.Elecraft K3: Check the K3 Programmers reference for all possible commands.
You can easily experiment with the filter codes using the {CAT* program macros.

MMTTY setup

For RTTY contesting N1MM permits using the MMTTY Engine, MMVARI and/or an external TNC.This configuration is based on using MMTTY for FSK and MMVARI for PSK.

  • Install MMTTY in TWO different directories on your hard disk.
  • Run both instances of MMTTY.
  • Click Setup | Setup MMTTY
  • Choose the Demodulator Tab

K3 and audio setup (digital)
Increase the Line Out level from the K3 (or the audio preamp gain in the microKEYER II with other rigs) until MMTTY’s FFT baseline comes up 6 – 10 dB. The receiver AGC will prevent overdrive and you want to give MMTTY’s DSP a fighting chance to get that signal that is slightly (3-5 dB) below the average noise level. Joe- W4TV
