Chas, I agree that the RX EQ setting should be saved, but save it along with the TX EQ settings in the TX Profiles. That way you can associate a TX profile with a particular operating mode rather than being restricted to just one RX EQ setting for a particular mode of operation. I have several TX profiles for digital modes and separate RX EQ settings would be nice.
Sounds like a great enhancement. -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Greene Sent: Monday, October 22, 2007 10:49 AM To: [email protected] Subject: [Flexradio] Receive Equalizer Hi, I have been using the receive equalizer to reduce some of the high frequency audio noise on the SDR-1000 which is particularity annoying when using NR. The audio noise is a problem only on voice modes such as SSB. However, when I use digital modes, the audio bandwidth is greater than for voice, and the equalizer adversely affects the receive audio bandwidth in the digital programs. I use a bandwidth of 5 KHz on the SDR-1000 for digital modes, and set MixW so one receive channel is receiving 0-5KHz and the other 100-3KHz audio, which shows any signal in the filter bandwidth but gives more resolution in the 0-3KHz range. The equalizer when set to reduce the HF audio noise in SSB, reduces the gain on the display above about 2.8KHz, plus it is broadly peaked around 2KHz. Similarly, there is a problem on the sound card RTTY programs such as MMTTY. Any one have the same problem? I plan to submit an enhancement request to either have a mode specific receive equalizer, or disable the receive equalizer on the digital modes as the transmit equalizer is disabled. I think having a separate setting of the equalizer both for receive and transmit for digital modes is a better choice than disabling it, as the peak around 2KHz can be easily corrected with the equalizer, giving a more flat response over the audio bandwidth for both receive and transmit.
