Re: Distorted audio on 15 M and then on 17M finaly FIXED

It is not related to G2, but Following this thread , a friend and I recently installed 50 ohm terminators on the two SMA ports (10 MHz input connector and transverter port) of our Anan 7000DLE and a 7000MKII (we had previously installed terminators on all the unused antenna ports). The result is a ...

Re: Anan G2 no front Distorted audio only 15 meter band

Someone on facebook claimed, that 17m is distorted after this fix. I verified that, and confirm the problem, if using more than 20-25W. Issue was fixed on 15m with ferrites, but now 17m is distorted. Any ideas? Ugh, yep I noticed now 17M now has the problem. I am not sure how to fix this. I will pi...

Re: Anan G2 no front Distorted audio only 15 meter band

All I have. That would be enough to fix the issue at hand. 5 min fix. Takes longer to take off the cover than apply the ferrites.

I fixed the audio issue on 15M by adding 3 type 31 ferrites circled in red.

Re: G2 RX2 & numb ADC1

So it appears this is a hardware issue, since Thetis is configured correctly as best as I can tell. I'm curious if anyone else has experienced this behavior before on the G2? I injected an S9 (-73dBm) signal into RX2 port and the 2nd receiver showed -115dbm response. That's -42dbm attenuation, makin...

Re: G2 RX2 & numb ADC1

Checked so far: correct ADC, bad database, old versions. Here's a couple of other ideas: - Perhaps there is a fault with the bandpass filters for the RX2 input. You might try selecting the bypass state on those. - Remove the covers and check for any loose RF connections or cables. Did RX2 ever work...

Re: RX2 & numb ADC1

Your FPGA needs to be flashed with version 12. When you say RX2 you are referring to your second receiver? I think this as does the main VFO works between ANT1, 2, and 3. Maybe someone who does diversity receive will chime in as they will know better. Best 73 John I just upgraded to FPGA version 12...

That's the first thing I tried. Do I need to update my p2app client to a newer version?

G2 RX2 & numb ADC1

I recently hooked up a receive antenna to the RX2 port on the back of the G2. I then pressed the RX2 button in Thetis and observed a noise floor of -132. This was very low for me. When I hook up the same antenna to Ant2 port the noise floor is -118. All of the signals on the 2nd receiver are all ver...
