To change bands you have to press F + 0 followed by F + 3 , this is the toggle function. Each time you enter the F + 0 and F + 3 the receiver will jump bands. To get back to 440 (where you started from) keep using the toggle sequence. If you did something wrong and the HT losses its mind DON'T PANIC! Just push the microproc. reset button. I have done this keyboard entery mod to my HT and it works. The sensitivity isn't great, but you can pick up any- thing that has a strong signal. This information was obtained from the local Standard representitive in Chicago. I'm sure there are other things This radio can do that I am not aware of, but when I find out I will post it here just for the heck of it. P.S. If I made a mistake in the key sequence list above I will post any corrections by the end of this week 10/30/92. good luck! Chris...

I too have a Standard C528 (as do quite a few of the other local amateurs here), and I'm very happy with it. In addition to the sequence you gave, there is also a (longer) sequence which enables wide-band transmit (how wide I don't know as I've no need to use it). There are also quite a few additional functions available off the keyboard from those documented. Appended below this is a table (which I keep as an Excel spreadsheet), listing the various functions in rather abbreviated form - I'd be very interested in learning about any others. Note the extra memory channels - there are actually 20 on each band, the upper 10 are accessed as shown below (accesed with a F+A prefix key, and displayed with a bar over the number). You can't use them in band scanning, but apart from that they function as normal memories.
