=> Display test / Rx Expanding;
   ----------------------------
   Turn the porto off, press the #,3 and the B, hold this buttons, now turn on
   your porto (Red Button), you will see now all the functions who are in the
   lcd display.
   When you quit pressing the #,3 and the B button, your porto can now go
   (On Display) from 100khz <> 999.90Mhz at the 2m Display, and on the 70cm
   Display he will go from 100khz <> 1310.00Mhz, of course he will not recieve
   from 100khz <> 1310Mhz, but the low vfo receive at least from
   126Mhz <> 190Mhz, the high vfo receive at least from 390Mhz <> 999Mhz, with
   some steps between 390Mhz <> 999Mhz where he not receive signals, because
   the vfo is out of his lock.

=> Enter Freq via keyboard;
   ------------------------
   When you enter a freq (in vfo mode) by pressing enter (ENT) you will see
   that you can press only the last 3 digits, this is simply to change by
   pressing the function button (above the ptt) and the set (8) button, push
   now with the ^/scan until you see on the display 'PL', now you can dial
   1 - 10 -100 = 1Mhz - 10Mhz - 100Mhz, set this option to 100 (dial), now
   you press the clr (*). Done !!!!
   If you now press enter (#) (in vfo mode) you will see that you now can
   press the whole freq. The same for the other vfo, this go's the same for
   1Mhz - 10Mhz  PL function.

=> Steps with the dial;
   --------------------
   Dialing a freq go's with steps in Khz, by pressing the function key
   (above the ptt) the steps will be now steps of 10Mhz.

Here are some RX reports by JBE;
