Check the archives for a message from me regarding the 207/2700/2710 issues. The use the same mic as the 2800. Basically, the mic has NO PTT. Only a data line that sends a packet on key down and on key up. Try keying the radio, pull the mic, continues to TX. Unkey, plug in mic, stays keyed, key it, radio unkeys, mic thinks the opposite with the red led... So, what you CAN do is to give up all mic features (remote) and run the radio in "stupid mic" mode where there IS a PTT. But, it ignores any mic data in that mode, and the mode is determined when the radio is powered up... not on the fly. I believe you either ground a line to enter dumb mode, or it is the opposite. Look in the service manual. I'm not near the service manual, so I can't help more. I don't think you are going to be successful without some way to intercept the data packets from the mic and change them or delay them before sending them on to the radio. I give ICOM a big thumbs down on this design... Now all of their radios are like this... a big step backwards. I ended up using my MIC-E as a power supply, RS-232 level converter and chassis for my Motorola Oncore GT+ GPS module, not as a TNC or MIC-E... Although, I did get it working well with my Motorola GM300 Maxtrac mobile, but that wasn't the original intent. Sorry to bring you such bad news. While not impossible, it will be a major undertaking to reverse engineer and build a circuit between the radio and mic, or, reprogram the MIC-E to decode the data coming from the mic, instead of looking for a PTT, and generating data to go to the radio. Worth the trouble? Probably not. Oh, giving up the remote control features of the mic? Not an option for me, as far as I am concerned. 73 Rick --- You are currently subscribed to mic-e as: lyris.mic-e@tapr.org To unsubscribe send a blank email to leave-mic-e-2619I@lists.tapr.org From bounce-mic-e-2619@lists.tapr.org Sat Sep 11 19:49:03 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.10) with SMTP id TAA21826 for ; Sat, 11 Sep 1999 19:49:02 -0500 (CDT) Message-ID: Reply-To: "TAPR MIC-E & PIC-E Special Interest Group" From: "KC5GOI" To: "TAPR MIC-E & PIC-E Special Interest Group" Cc: "TAPR MIC-E & PIC-E Special Interest Group" References: <3.0.1.32.19990911165421.00942300@24.234.57.59> Subject: [mic-e] Re: MIC-E problem.

I have another brand of radio I have been using with an APRS Mic-Encoder, but there is no PTT line on the microphone plug. Instead, the PTT signal is encoded on a serial stream of data to the radio from the microphone and the radio decodes the information. The APRS Mic-E does not work with this type of arrangement at all, unless you get real creative with some fancy modifications to the radio. The radio I am using has a 1200/9600 packet connector on the back of the radio that I wired to the Mic-E, but I had to modify the radio to the get a decoded PTT signal back to the Mic-E so it would hold the PTT line at the packet jack on the radio. Unfortunately, when the PTT is dropped from the microphone, the radio unkeys before the microprocessor in the radio looks at the PTT signal at the packet jack. This is a real pain. The result is that my signal drops momentarily when I unkey the microphone and rekeys the transmitter when it discovers that the PTT is activated from the packet jack (PTT challenged). So, when I am on a voice repeater and unkey the microphone using my Mic-E, there is a short squelch tail before the data from the Mic-E is presented at the end of a transmission. This requires the end of transmission to be longer in order for the transmitter to settle and send the APRS posit which equates to about 200-300ms longer than what it really should be if the transmitter did not drop in the first place. Considering that most courtesy beacons are more annoying than the Mic-E posit, it may not matter anyway. Anybody who wants to use a Mic-E or similar device on some of these new radio's should be aware of this condition as a Mic-E will not work without some radio modification if the radio does not have a dedicated PTT line. In some cases it may not be possible or require major effort. If one wants to merely use a radio for APRS on 2M just to beacon on the APRS network, most radio's that have a packet data jack or a true hardwired old fashion PTT line on the microphone jack can be utilized. Most can be modified if they do not meet the above requirements. However, my point is specifically directed to those who may be interested in using a Mic-E or similar device to attached an APRS packet posit at the end of a voice transmission. 73's, Tim - N8DEU Huntsville --- You are currently subscribed to mic-e as: lyris.mic-e@tapr.org To unsubscribe send a blank email to leave-mic-e-2619I@lists.tapr.org From bounce-mic-e-2619@lists.tapr.org Fri Sep 24 22:45:40 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.10) with SMTP id WAA09480 for ; Fri, 24 Sep 1999 22:45:38 -0500 (CDT) From: smorris@mindspring.com Message-ID: To: "TAPR MIC-E & PIC-E Special Interest Group" References: Subject: [mic-e] Re: [ss] Re: info Date: Fri, 24 Sep 1999 23:45:54 -0400 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2615.200 List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio Reply-To: "TAPR MIC-E & PIC-E Special Interest Group" X-Message-Id: <001d01bf0708$7897a480$0501a8c0@smorris> Sender: bounce-mic-e-2619@lists.tapr.org Precedence: bulk Tim, Actually what you would want to do is use the Data connector for your TNC, and then the microphone would be used on the other band (VHF or UHF) for voice.
