<div dir="auto"><div>One of the nice things about using a dual receive aprs radio like the Kenwood D710 is that you can set it to not transmit aprs while the squelch is open on the other side of the radio. The basically eliminates desense problems. It also takes care of all the aprs magic for you and when paired with a bluetooth adapter and tablet makes a super slick setup.<div dir="auto"><br></div><div dir="auto">As far as power goes i find that around los angeles where I live 5 watts is plenty because there are plenty of digipeaters and igates. On open road, out in the desert and in the mountains it is nice to be able to turn the power up though.</div><div dir="auto"><br></div><div dir="auto">-Jess</div><div dir="auto">K5LLI </div><br><div class="gmail_extra"><br><div class="gmail_quote">On Feb 5, 2018 7:46 AM, "Fred Hillhouse" <<a href="mailto:fmhillhouse@comcast.net">fmhillhouse@comcast.net</a>> wrote:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="blue" vlink="purple"><div class="m_-4474117133162274588WordSection1"><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">When running in my car, I use 25-40W which is more than adequate depending on the radio (one is fixed at 40W).

(I'm still digesting all the great comments from my previous query.) He said I will need a minimum of 50 watts and the frequent transmissions will pretty much eliminate the possibility of other 2 meter operations while I have the APRS running. This news is certainly disconcerting. My original intention was to use a Raspberry Pi with a TNC-Pi connected to a Kenwood HT with an external antenna. Having to add another full sized mobile radio and running that much power with all the other radios in my truck might be an issue.<u></u><u></u></p></div><div class="elided-text"><p class="MsoNormal" style="margin-bottom:12.0pt">So, is the need for 50 watts realistic?
