2 footswitches on 6600m?

Hi all

Has anyone been able to have 2 footswitches connected to a 6600 at the same time, one for slice a and one for slice b?

If so, how was this achieved?

    There is only one transmitter, therefore no extra foot switch needed. One chooses which slice has the transmit function by selecting the slice for transmit (in the slice flag or on 6600M front panel), then activating td transmits on that slice’s frequency.

    [edited to add:] I guess you could achieve what you appear to want by using software to translate a particular foot switch to a macro that would select the slice to tx, then issued an electrical or CAT command signal to transmit.

    If two operators are using multi flex, each can have an individual foot switch, wired in parallel to the ptt. Each would need to select the tx on the slice before transmitting.

    I'll add some more context.

    I want to do SO2R and have a foot switch for each slice and not have to manually change the tx focus first.

    Just to be able to hit a foot switch left or right and ptt the appropriate slice.

    Sounds like you want to manually change focus with your foot, rather than your finger.

    If the foot switch controlled software you could make that work.

    Hi Rich, I do something similar with the mic switch on my TeensyMaestro. In my case, I automatically change mic profiles when I select between mics, in your case you would like to change the TX flag based on switch activation.

    As Ted mentioned, this could be done with software, but someone would need to write it. The GPIO pins on an Arduino, Teensy or Raspberry Pi (among others) could be used for this purpose. You could also write code for your computer that uses the control signals of a serial port for the purpose.

    I think that this is completely do-able, but would take someone to sit down and create it.

    I think you will find using the keyboard the better solution as that is the way it was designed.

    SO2R utilizes OTRSP and by moving the Transmit Focus in N1MM it will also move the TX focus on the radio. It works very well.

    N1MM also supports dual keyboards

    Two Keyboards – Enables the use of two keyboards, one for each Entry window. Plug in two keyboards before starting N1MM Logger+. The first keyboard you type in after starting the program will control the left (Radio 1) Entry Window. The other keyboard will control the right (Radio 2) Entry Window. The pause key is disabled, since you no longer need to be able to switch Entry windows from a single keyboard. The \ key moves keyboard focus to the Entry Window associated with that keyboard without actually sending any keyboard commands to that window. Note that the use of keyboard remapping software, such as AutoHotKey, may not work correctly with two keyboard operation.

    SO2R Key Assignments

    Ctrl+Enter – Send next ESM state on alternate radio (assuming ESM turned on).

    Ctrl+F1 to F12 – Send Fn message on alternate radio.

    Ctrl+Left Arrow – In SO2R move both Transmit and Receive/Keyboard focus to left radio, or in SO2V move both TX and RX/Keyboard focus to VFO A.

    Ctrl+Right Arrow – In SO2R move both Transmit and Receive/Keyboard focus to right radio, or in SO2V move both TX and RX/Keyboard focus to VFO B.

    Pause – Move both TX and RX Keyboard focus to other radio (or other VFO in SO2V). If TX and RX focus are split when you hit pause, TX focus will move to where the RX focus is.

    Ctrl+B – Dueling CQ’s will send CQ (without delay) alternately on each radio. If Dueling CQ’s is turned on, both radios become run radios. Dueling SSB and CW CQ’s are supported too.

    Grave accent, backquote, or unshifted tilde key (~) Toggle STEREO mode on/off, or toggle Auto/PTT modes with modified DXD . Notes: On US keyboards, the key we are talking about is the key just to the left of the number 1 key.

    Ctrl+I – Toggle SO2R Mode (Soundcard). Toggle through the SO2R modes supported by the program. Only operative in ‘$5SO2R’ when N1MM logger controls the audio, not when using an external SO2R controller.

    Ctrl+PgUp/Down – When changing band using Ctrl+PgUp/Down will skip the other radio’s band.

    Ctrl+Shift+K – FocusOther, Another method of automated focus control. Forces entry focus to non-transmitting radio, with entry focus returning to the transmitting radio as soon as it reverts to receive. See SO2R. Disabled in SO1V mode.

    Ctrl+Shift+L – Toggle CTRLFx Macro. This macro allows the user to send on the other radio (RTTY and CW only).

    Thanks Mike

    I am a dxlog user and have asked on their forum how transmit focus is fine. I can press * or CAPS which changes the logging focus from slice but the TX focus doesn't. This would be a second best if I can change it on the keyboard, am just trying to find out how!

    Hi Rich

    There shortcuts are here: http://dxlog.net/docs/index.php/Keyboard_and_text_functions#SO2R_and_SO2V

    You may want to ask them how to switch TX focus to follow the OTRSP design. The good news is the command being sent is easy to see since you can actually see the commands in SmartSDR CAT/OTRSP. All they have to do is the same thing.
