Push to Talk (PTT) button.Mobile phones do not have a PTT button, and there is no clear candidate for this button on this phone. The Finnish software had the MPTT and the SPTT options, but in many people's opinion, the M requires too much pressure, and the S on the top of the handset is too far away from a natural position of the hand. Some years ago, LA7TM patched the binary code (ver 1.4) to make # the PTT. Then the * has the function of the original # (enter frequencies, memories etc), and the M on the side enables transmission with a 1750 Hz tone (S for the CU53 handset as there are no right-hand side buttons). The software therefore has a new option, HASHPTT, in addition to the original MPTT and SPTT.
Norwegian key-pad.The Norwegian telephone key-pads in the mid 80's were different from the international ones. At that time, the Norwegian PTT required all telephone key-pads to be equivalent to those of calculators in order to minimize confusion. Actually this was a very good idea, but it was abandoned a long time ago as it is very costly to have particular national requirements in the global market place. The MD59 and MD50 in Norway had calculator keypads:
1 2 3 7 8 9
4 5 6 4 5 6
7 8 9 1 2 3
* 0 # 0 * #The MD50/MD59 software now has the NORWAY option to select this keyboard.
Software for MD50/MD59The software version on this web page is based on the same source as the OH5NXO/OH3NWQ software. Download our tested version of the MD5x software for Norwegian keyboard (also found on the OH3NWQ site).
