I downloaded the Lincon II manual and if I can infer from the text,it appears that a PL/DPL code can be programmed independently for transmit and receive as is the offset. It's unlclear if it's just a global memory or linked to a particular channel.
The radio also seems to have a hysteresis type squelch setting.
This is a big problem with these radios as they may be claiming amateur, but not appropriate. I was eyeing the SR-59 that Simon was reviewing. Seemed to be tempting to go mobile again with something so small that covers amateur bands in AM/FM but no split nor tone I could tell.
I'm surprised there is not that much attention to real amateurs. The amateur versions of the HR series and Radio Shack units were very well received, but very flawed. Chipswitch helped on some accounts. I bought an Optima import that generated quite a bit of interest locally. Good radio for SSB, but still very flawed for FM use where I kept a Kenwood TK-6100 commercial unit programmed for FM use along side.
