Extended Frequency Range (5200): Effect: set receive and transmit range. Bad effect: ARS gone. This is based on information from Yaesu in Japan. These jumpers are located in the main radio case. For location, refer to the FT5200 Technical Guide. 1) Close (short) JP5001, JP5002, JP5003, JP5006 and JP5007 2) Remove (open) JP5004 and JP5005 The frequency range possible will now be approximately : VHF Rx 110 - 180 MHz Tx 130 - 180 MHz UHF Rx 330 - 480 MHz Tx 425 - 465 Mhz The radio's alignment was done at the factory for your original frequency bands and so there will not be optimum behavior outside these ranges. Broadening the alignment will sacrifice performance at usual frequencies. In practice, the alignment does not need adjustment. You can program the frequency limits now. [ed - note the similarity (and dissimilarity!) to the 5100's program-limit sequence above] 3) Press and hold [D/MR] [F/W] [REV] keys and turn radio on. 4) Program in VHF low edge of Rx VHF high edge of Rx VHF low edge of Tx VHF high edge of Tx 5) Repeat for UHF in the same order. I [John] have not done this so I can give no further advice on programming. Attributed: John Newgas, G7LTQ jnewgas@cix.compulink.co.uk g7ltq@g7ltq.ampr.org
