HT50/ P100 Out of Band Programming Taking a P100/ HT50 out of band is VERY simple. Unlike later Motorola products, the archive file is actually a straight hex/binary file. Just program everything except the frequencies like you want it, and save the archive. Use your favorite text editor to fix up the frequency info and save it. Then, read the archive with the RSS and, without making any changes, program the radio. If you attempt to program an out-of-band frequency, the code plug WILL accept the information. However, the RSS will notify you that the frequency is out-of-band and to Return the radio to Motorola for service. If, for instance, you convert an HT-50 to amateur service, what is needed after programming is a field alignment. This essentially consists of aligning the (4) receive helical resonators per channel for maximum noise, as well as adjusting the PA for each channel for maximum output. If aligned properly the receiver is quite hot. The HT-50's are capable of +-5 MHZ out-of-band. Attempts to go farther than this range will result in a very unhappy PA section and a very deaf receiver. The only bad news is that the VCO is a sealed unit. So, some P100's will go farther out of band than others, and there is no alignment tweak to extend the range. Most will do at least 2 MHz and some as much as 10 or so. Out of Band Programming, Method 2 This method should work for VHF radios. For out of band programming, just edit the last 3 bytes before FF FF FF FF series at the end of the archive file. They should be changed to from 03 78 36. This should open up the full VHF range for the radio. The only limitation you will run into is the VCO. Depending on how far out of band you go, you may find degraded RX sensitivity, low TX power, or both. If you go too far, the VCO may unlock completely, and the radio will not TX/ RX on that channel. Channel Expansion It is.
