Re: ANAN-8000DLE - permanent ADC overload

I just got the info from another ham running an 8000DLE who uploaded v2.4 and he experienced the same problems. So he went back to v2.3 and all is fine. Therefore it is definitely a firmware bug. As I wrote in some earlier post when I did some measurements on the relay coils while switching thru the...

Re: ANAN-8000DLE - permanent ADC overload

Problem solved (so far)! the original firmware version the radio was deliviered with was ver. 2.4. After loading the latest "official" firmware Ver. 2.3 (to see whether the process of uploading was successful) I took the chance and tried enabling ALEX on 10 & 12 m. Guess what - the rad...

Re: ANAN-8000DLE - permanent ADC overload

Hi Scott, this afternoon we flashed the firmware however no change. The relay matrix control seems to be completely off track as like described before whenever ALEX is enabled the relays for the 6m path are activated too while being on 10/12 m. Where this huge 25 MHz spur is injected I don´t know. T...

Re: ANAN-8000DLE - permanent ADC overload

Meanwhile after discussing with some people offline it is pretty sure that it is not a firmware problem. Thats why I didn´t reload the firmware so far. Besides that it is not as easy as assumed especially as different (competent) sources describe routines that conflict one each other in some but imp...

Re: ANAN-8000DLE - permanent ADC overload

The 6 m preamp is disabled on TX but not on RX (these are still the default values which I didn´t change) ALEX enabled Checking the RX box on "Disable 6 m LNA" doesn´t change anything. Same with "LNA 15/12/10M". No change in the artificial noise floor nor do I hear a relay clicki...

Re: ANAN-8000DLE - permanent ADC overload

Yes the voltage is o.k. - it measures 13,9 V. After moving around the bands for a while yesterday I enabled ALEX again and again and all of a sudden the "ADC Overload" flag was gone on all bands but 10 m. Even with the attenuator set to 0 dB I could not provoke an "overload". On ...

ANAN-8000DLE - permanent ADC overload

Hello, I got a strange phenomenon with an ANAN-8000DLE which I got a few days ago and wonder if it is just an operator error or something serious. Here is the story: When I used the radio the first time I noticed an "ADCx overload flag" on the 10 m band ( I don´t recall whether it was ADC1...
