Save Power up settings to reinitialize the EEPROM in microKEYER, close Router to save the settings
and then restart Router.
FSK or CW messages
PTT ON/OFF is not supported as an embedded command in the MK2R. Use the F10 key from the
PS/2 keyboard.
RF problems with my MK2R
The bypass modification for the microKEYER II has not been evaluated for the MK2R+. However, due
to the layout it will not be as simple as the microKEYER II version. Circuit grounds for the USB "core"
and the balance of MK2R+ are separated and there is no conveniently located place for field
installable bypasses.
1.3 N1MM logger
1.3.1 "PTT line" (usually RTS) on a serial port
One note with regard to N1MM Logger (and other logging/control software) ... DigiKeyer and other
microHAM interfaces responds to the "PTT line" (usually RTS) on a serial port. The interfaces do not
respond to "PTT via command."
In using N1MM with microHAM Router, it is best to set the PTT delay in N1MM slightly longer than the
PTT Lead (microKEYER, microKEYER II, MK2R/MK2R+) or PTT Delay (DigiKeyer) parameter.
N1MM Logger will begin producing audio (AFSK or Voice macro) when its delay time expires. If
Router's PTT Lead/PTT Delay is longer, the transceiver will not have switched before
N1MM Logger starts generating audio. A good starting point is to set N1MM Logger PTT delay to 20
msec and Router's PTT Delay to 10 msec. If the particular configuration does not require a delay for
receive antenna switching (LNA PTT) and the logging/control program provides its own PTT delay
(like N1MM), it is even possible to set Router's PTT delay to zero (0).
Always uncheck "PTT via command" when using microHAM Router. If "PTT via Command" is used,
the PA PTT and/or LNA PTT outputs on the microHAM interface are not usable because Router and
the keyer have no way of knowing that N1MM Logger has commanded the radio to begin transmitting.
The PTT delay setting in N1MM Logger and the PTT lead or PTT delay settings in microHAM Router
should be adjusted for the particular installation. The PTT Lean/PTT Delay setting in Router should be
less than the PTT delay in the logging program. Router's PTT Delay will control the delay between PA
PTT/LNA PTT activation and the activation of the transceiver PTT. The logger PTT will control the
delay between activation of PA PTT/LNA PTT and the start of RF.
If the PA relay was very slow one might set PTT delay in N1MM Logger at 40 mSec and set PTT
Lead/Delay in Router at 30 mSec. In that case PA PTT would activate as soon as the operator
pressed an F−key while the radio PTT would activate 30 mSec later and RF (audio/CW) would start
10 mSec after the transceiver PTT. With hand mic PTT, the amplifier would still receive its PTT
command 30 mSec before the transceiver to allow time for the (slow) relay to switch and settle.
1.4 Station Master information
Quick Guide
Connect iLink cables between MK2R and Station Master•
Check the "iLINK Couple" (frequency source) setting in Ports tab Station Master.•
On SM: Go to MENU mode (push MENU button for more than 1 second and Select *** CAT
*** (SM will follow radio)

Relays Station Master (Rotator interface)
All of the relays in Station Master are Forward model N4100HS3DC12. The specification on the case
says: 3A/125VAC/30VDC.
Although the Tailtwister is specified at 2.25A operating, remember that the starting surge will be
