This information is intended for educational (and/or entertainment) purposes only! "How easy is it to unlock the Alpha channels?" Well it is very easy, dare I say "too easy"!! This lovely Cybernet chassis radio has the PTBM092COX PCB, used in several mobiles like the GE 3-5804D, Midland 77-830, 77-882, Ham-International Puma, & Colt 870. It is somewhat similar to the PTBM094COX used in the "Ham-International Viking", & Formac 88; of course we didn't get the PTZZ033AOX FM board or PTOS008AOX for bands here in the states. One nice thing about these vintage radios, they utilized 02A PLL!!! (US) AM only, Cybernet radios with PLL02A & 2 crystals, 10.240 MHz + 10.695 MHz use N-Codes in the range of 330 to 286 for the "mid block" or standard FCC 40 channels If we change the least significant programming bit (Pin 15, p0) we can access the "skipped channels"! and so here is the "cheat sheet" I'll spell it out for my brethren who may have a difficult time.. Ham International posted a "how to" that includes an inverting circuit for push button operation. Shout out to "Night Ranger" for the N-Code truth table, thank you very much!! All the best!
