This would be good on the Wiki. There were quite a few Phoenixes used for packet repeaters at one time. They come up every now and again for reasonable pricing ($5 and $3 for mine at a flea market). We should swap notes after the holidays. I was getting reasonable performance with my SX and OT2 in my vehicle. Your connection sounds similar to mine. Happy holidays! Fred

There are two ways to do it....The easy way and of course the way I did it:) I will do a write up on January. But as a summary I added a de-emphasis network so that I could use voice alert with the original volume, speaker, and PL decoder. In other words leave the factory audio path intact. After all of the PL filtering, but before the monitor switch I tapped into the audio, added an amplified de-emphasis network, the output of which is the input of the version .9 T2-135. I will perform decoding analysis with the write up. Mark KC5EVE At 07:51 AM 12/18/2009, you wrote: Hi Mark, I would like to hear more about the Phoenix install. I used a Phoenix until recently with my OT2. I will be running a FT1500 again mobile. The Phoenix is moving to a digi site (with the KPC3+). Thanks!

And put the original in another radio that has a de-emphasis network (Fits easily in a GE Phoenix!) Mark KC5EVE At 07:27 PM 12/17/2009, you wrote: Thanks for the comments. I have a local event coming up at the end of February for which I really wanted to have an effective fill-in digi available. I used my existing board last year for the same event and it was OK but certainly less than ideal. Based on what I've heard here and in past posts as well, I've ordered a new board and will keep the original one as a spare. I had actually started considering acquiring a KPC-3 for use with another radio, but this arrangement is so compact that it's hard to beat (providing it works satisfactorily - and it sounds as if the new board will be noticeably better).

I know there's been past discussion about the decode performance of these units and I'd just like to get updated on the status of any fixes. I think there was talk of some hardware changes to better shape the audio, but I don't know where that stands now. > > I do have the latest firmware build installed (55076) and today I was running my DR-135 system next to my other home system using a Yaesu FT-1500M and AGWPE and the home system is decoding many more transmissions than the Alinco. I'm using two identical antennas at the same height with just about the same transmission line lengths and quality. The Alinco gets most of the strong signals, but the weaker ones are not handled well. The radio hears them (the "meter" moves) but the board does not decode them. > > So, is there a practical fix for those of us who are a little hesitant about surface mount techniques? > > Gil Chapin, WB2UTI >
