I hope a fix is on the list to bypass the TXEQ when playing back an off-the-air recording. Roy Morris W4WFB
Subject: Re: [Elecraft] About DVR To: Hector Padron <[hidden email]>, [hidden email] Message-ID: <[hidden email]> Content-Type: text/plain; charset=UTF-8; format=flowed Hi Hector, you can play back him on the air with no problems. But if I remember correctly, the received/recorded audio passes thru your TX equalizer, so the "remote" station hears how he sounds with your own tx equalizing applied on it.

For now, a quick workaround is this:
1) Set up your data mode to be DATA A and the same sideband as you are using for voice. 2) When you wish to playback a recording off the air, tap mode down twice to get from SSB to DATA A. 3) Send the recording. 4) Tap mode up twice to get back to SSB. --- Data A automatically sets Tx EQ to FLAT, and disables CMP, while switching back to SSB mode restores the settings for both. Of course, if you are using FM or AM, this won't work. 73, Lyle KK7P > I hope a fix is on the list to bypass the TXEQ when playing back an off-the-air recording. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Don't you have to receive in DATA A as well in order to get RX equalizer out
of the circuit? Or is that not in the recording loop?

Yes, it is in the recording loop. The DVR records what you are
hearing. If you have EQ other than flat, it is applied. Think of the DVR as a speaker, and as a microphone, and you can visualize where it in the the system. Note that the Rx EQ and Tx EQ are *not* separate filters, but are simply instructions to the DSP for the signal audio filter (Tx or Rx) that it builds for audio processing. The only cascaded operations are Noise Reduction, AutoNotch, and AFX. Even the manual notch is just telling the DSP more details about the single audio filter it is building. Thus, it is not possible to have the DVR record "before the Rx EQ" while you have Rx EQ applied to what you wish to hear. It is going to record what you hear, and what you hear includes the Rx EQ. Similarly, it is not possible to have the DVR inject audio "after the Tx EQ" or "after the CMP" for similar reasons. 73, Lyle KK7P > Don't you have to receive in DATA A as well in order to get RX > equalizer out of the circuit?

Lyle, That makes perfect sense to me. When you tell send someone what they sound like at your end it should sound like what you hear. When one is using an equalizer they should make sure when they send someone a sample of what they hear, they tell the recipient the recording was made post equalizer. Then they can decide if what they hear is valid. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Life Member 35102 ARRL Life Member Retired Professional C# Software developer http://www.n5ge.net On Fri, 21 Jan 2011 13:11:49 -0800, Lyle Johnson <[hidden email]> wrote: [snip] >Thus, it is not possible to have the DVR record "before the Rx EQ" while >you have Rx EQ applied to what you wish to hear.

Except what you can do is to send back to the other end what was coming in
off the air. If I ask someone to send my signal back to me what I am looking for is a mirror, not the other guy's personal speaker equalization. Tell him to transmit, switch to data A, record, send the recording back, switch to SSB. He hears what he was sending. He could be a little muffled to everyone else, but if you are running sharp treble in your RX equalizer because you like it that way, that will be added to the resent signal, and he will sound normal, even though in fact he is sending muffled highs. 73, Guy.

Hi,
i programmed a macro to do this and also switch to TX-mode, the 2nd macro restores my TX-EQ settings: Replay: TE+00+00+00+00-00+00+00+00;TX;SWH23; Restore settings: TE+10+16+03-04-04+02+13+13; Assigned it to PF1+2 73 Michael |
