For those of you thinking about building or upgrading your 2 meter machines,
there are several duplexers listed now on Ebay that will

You can send the preamp back to ARR for about 35.00 they will rebuild
and tune to freq. Having over -137dbm for the squelch i would not

I have the TOT in all my radios set at 30 seconds and building a 2
