Version 40 "beta" Island Keyer II changes / feature additions to version 14, 32 & 37:
for the low power version: Keyer power supply voltage is now 3.6 volts maximum, V40 will not work at 5 volts
a higher power version of V40 is available which will work at 5 volts
serial numbers below 100 can now optionally be played with leading zeros
a numbers only keying mode is now available with self completing characters for high speed contests
a "Both Tune" keying mode is now available which enters tune mode if both paddles are pressed
an iambic to single paddle keying mode is now available which only responds to the first paddle touched if both are pressed
Version 37 "beta" Island Keyer II changes / feature additions to version 14 & 32:
speed range is now 6 to 80 wpm
?Sxx embedded command now increases the current speed by xx wpm
new ?Ix embedded command increases the character space length by x dit spaces
Version 32 "beta" Island Keyer II feature additions to version 13:
5 didah entry to CE can now be turned off
"paddle" outputs on pins 17 & 18, allows the Island Keyer II to
"key" another keyer, useful for transferring memories to a rig or another keyer
"backspace" added to memory recording, easy delete of last character recorded
alternate "spread" multipress combinations, gets rid of adjacent switch accidental presses
auto alternate play of a different memory after x normal memory plays
autoresume embedded pause, ?Q
5 didah or 9 dah entry into Command Entry mode
CL command: compensates for transmitter shortening of code elements
DF command: current keyer speed can be divided by 10 or 100 during memory sends
Beacon Key down: Island Keyer II can be easily used as a "fox" FM beacon
