thanks for the tips HRM . one of the nice things about where you are at is you get the best of both worlds ... texas and loisiana cooking ! another member here is going to graciously provide a more complete data set . my plan of attack includes a thermos of tea and a bottle of aspirin . i will post my findings once the fix has proven to be correct and stable . heh ... the old loran radio (not used for a long time) is/was being used as a *placeholder" in the console ... the NiCd back up battery decided to puke its guts out . the electrolyte made an absolute mess of the pc boards ... it is now a worthless paperweight . this is good though ... i am trying out a new gps program that allows me to download the tiles from google (and other providers) and stash them on the HDD or flash drive . the plan is to ultimately build an on-board comp that uses a "ublox" gps receiver module and has a touch-screen display . (i could always purchase a gps unit complete , but where is the fun in that) yeah ... add that project to the others ... including the GF making (more) noises about painting the house . ___ sigh ___ ps ... the fly-in at grygla is this coming weekend .

thanks for the information ... i can't remember if i sent a "thank you" already ! too much "stuff" going on . i have to get some things done before the fly-in at grygla, mn on sunday . at least i think it is this sunday ...

thanks for the welcome and thanks for the schematic excerpts ... they will help out ... time to fire up the o'scope and soldering pencil . @ robert : i am not sure if the audio out on the 155/165 is a "balanced" type (think why the old telco stuff did not pick up noise and hum with lines miles long) . grounding one side would create an "unbalanced" condition (think guitar or most headphones) . this may cause "noise" pickup ... unless the output is low impedance (say , 8-200 ohms) . ahhh ... if i had the manual ... i wouldn't need my crystal ball . off to dig into the radio . ps ... i'll PM you my email ... much appreciated .

hey all , i am trying to find the schematic for the mentioned nav/comm tranceiver . (owner/op manuals abound on the 'net) the receiver breaks/trips the squelch without the reception of a signal ... pressing the transmit button a couple of times usually clears the problem . the problem becomes worse as the radio/cluster "heats up" . the second KX 155 works ok . many thanks in advance
