Steve,If you don't have the MCP-4program try this:1) store the rx frequency in a memory channel.2) press VFO To enter VFO mode3) enter the tx frequency4) press  "F" and select the memory chanel with the rx frequency you stored in step 15) press OK While holding the PTT and it should now store the tx in the same memory channel.You can check by if you +- where the offer symbol is for regular repeater operation you got it. You should also see the frequency display change when pushing the ptt.Gl& 73Rick Tejera (K7TEJ)Saguaro Astronomy ClubWww.saguaroastro.orgThunderbird Astronomy ClubWww.w7tbc.org -------- Original message --------From: Steve Kristoff skristof@etczone.com Date: 5/7/21 14:33 (GMT-07:00) To: amsat-bb@amsat.org Subject: [AMSAT-BB] Help with TH-D74A

I am trying to store the odd-split frequencies for NO-104 (DTMF) in the memory of my TH-D74A. I downloaded the official manual, but I can't still can't figure out how to get anything in memory much less the odd-split frequencies. Can someone please point me to a video or a set of step-by-step instructions? I actually have the DTMF tones encoded, I just can't figure out the odd-split into memory part. Thanks in advance.

I have the DTMF uplink frequency 145.980 set to NFM in B band with the 145.825 APRS frequency set in A band (and enable all the correct the APRS features). I assign the PF2 key as DTMF ch 0 where I have the correct DTMF tones stored. You can assign those frequencies as memories to ID them. I'm not 100% sure if the D74A actually TX in NFM though since the NFM is set in the RX menu. Others are getting in with the 74 at five watts, so it's possible

With the D74A se up this way, youI can RX and decode APRS packets and messages from PSAT2 along with voice as well (I have PF1 assigned to REC). Just hit the PF2 key to send the tones on 145.980.

It's a neat satellite...
