Need Quick Help with 2 Meter TX

  • Updated 5 years ago
I have just returned to 2 meter 2 EME in a small way. I am sending tones from MAP65 thru LINE to the 6700 using DIGIU mode. I can see a transmit tone spike on the 6700 display spectrum, but there is no RF output. If I switch to CW mode and send with my key, the RF is there OK. Can someone explain? I am anxious to get this going in the next day or two.

Dave, I'm assuming here that you are sending the tones from MAP65 through the LINE input pin of the accessory connector on the back of the 6700. From what I can determine, if you click the flyout to set the AF Input Source on the P/CW panel on the right side of the screen (the flyout normally reads "MIC") and click on ACC, it should transmit the tones. Frankly I'm a little baffled what the LINE selection is for in this flyout, but from my reading of the latest SmartSDR software manual it looks like it wants to be ACC. When you select that, the +ACC button on the same P/CW panel should then light up. You may need to click on that as well.

I hope this helps.

I am putting the LINE tones through the BAL-IN audio connector on the rear of the radio. This worked fine until I upgraded to v 1.03.041. I see the tone signal on the panadaptor, but I do not see any RF output. I just got a couple antennas back up and am anxious to try them. This is stopping me. The only way I can get tones to work is by holding an earbud up to the mic, and selecting mic. THIS IS NOT ACCEPTABLE. CW and ssb work just fine. It's just the LINE input that is not working.

Is LINE selected as the input and the DAX button un-clicked (not illuminated)

Yes Tim, could you check to see if this is working there at the plant on 2 meters? I tried BAL and LINE, the green level indicator is moving way up, but no RF out. I had this working before upgrading.

I did not realize you were using the BAL-IN connector on the rear of the radio. In that case, select BAL on the flyout for the AF Input Source. If that still does not work, there may be an interaction between the DIGI modes and accepting audio from that connector. A possible work-around in that case would be to use USB and configure your transmit passband and processing accordingly.

OK, BAL is working for me with DIGU. Whatever happened to LINE input, I used that before. Perhaps I should have always used BAL. Anyway all is happy now.  BTW Army I only have 2 non elevating antennas on 2 now, fixed at 5 degrees EL.
