Then short jumpers 1-2-3-6-7 . Some jumpers are still shorted depending upon the country version. Remove the Jumper number 17 for cross-band operation . For resetting the unit press D/MR -- F/W -- REV buttons in the same time and switch on the transceiver. The display must show now 300.000 on the right and 000.000 on the left . You must now program the lower and upper bands limits on RX and TX as follows: After resetting the channel number digit on the left of the display is showing a ""1"" blinking .. With the vfo knob and the MHZ button increment from 000.000 to the desired lower VHF frequency with 1 Mhz steps . The press the D/MR button to lock the frequency . Now the channel digit shows a blinkin""2"". Increment the display to obtain the VHF upper limit . Press again D/MR to lock the frequency and obtain a ""3"" digit channel blinking .. Increment the display value with the vfo knob to fix the TX VHF lower limit . Push D/MR to lock the frequency . The digit channel is blinking with number ""4"" and program the upper TX transmit limit . Press again D/MR , the display is now reversed from left to right and program the UHF TX/RX limits with the same procedure used for teh VHF band. ------------------------------------------------------------------------------ For cross-band operation , press the RPT button when swithching ON the tranceiver . Adjust the audio level with the volume control and balance . ------------------------------------------------------------------------------ For wideband Uhf RX operation the frond end coils with metallic cores must be realigned to spread the sensitivity of the receiver. A swept oscillator with scope should be employed eventually . 73's from F6DWP =============================================================================== Note: I haven't tried or verified this, proceed at your own risk.
