FT-726 receive very poor
can anyone assist...
i picked up a FT-726R, untested and with no warrenty recently and it has 144 and 50mhx modules .... my questions are .. 1, the receive on 144 is very poor, i can only just hear the local repeater, i have tested with my handheld and i can receive at 59 plus when transmitting next to the radio but the gain is very bad ... any ideas.. i did see in a earlier posting that maybe the BF981 might need replacing ... an i correct or can anyone help. 2, the 50mhz module has no cables .. Grrr :-(, can these be made up, do the have to be shielded? 3, I disconected the 144 and wired up the 50mhz module in it's place and i got a E on the display ... can the 50mhz module be run on it's own ? appreciate any help with this, and any more that i find on the way to repairing this radio. thanks for reading Mike |

Well it looks like i may have found some of the problem, after
tracking down some of the voltages listed in the tech manual, i seem to have 2 x µPC1037H failed on the RX board, Q10 and Q11 since they are giving out no readings at all. ( DEAD ) now does anyone know where i can get hold of 2 x µPC1037H or there equivlents thanks all Mike Lynn |
