Re: Anan 8000 and WiFi

You have two problems. The first problem is that you simply don't have it set up correctly. See this thread to get that part fixed: https://apache-labs.com/community/viewtopic.php?f=22&t=2464 Once you fix that problem and are actually able to run the radio, you are going to find that you have a ...

Re: Accuracy re fidelity on/with the TX display while using PS

These sort of multipath problems are largely avoidable. The entire point of having and using a coupler is to avoid them. If you don't trust your coupler, then put the coupler on the test bench and test it. If you don't trust the DUP display, then take the output of the coupler, pad it down a bit if ...

Re: Accuracy re fidelity on/with the TX display while using PS

Rob, In your two-tone case you are demonstrating that results on the RSP1 are better than that shown by DUP. IMD products on the DUP display are down around -60dBc. On the RSP all you can see is the phase noise, probably mostly from the RSP1. The noise floor on the RSP1 appears to be -70dB from the ...

Re: Guidelines For Best Transmitted Signal Quality With Digi Modes

Couple more questions. What is a "good solution" for Single Calibrate? How does one know? In DUP mode look at your IMD products. If the close in ones are down -50dB or more, then it is good. And I guess the "Correcting" means Pure SIgnal is doing it's thing? Yes. Is this appropr...

Re: Guidelines For Best Transmitted Signal Quality With Digi Modes

Thanks a lot for posting this.... Couple questions #1 Where is the ALC setting? There is no ALC control per se. Switch the meter to ALC during transmit. Adjust the audio drive level from your digi mode program upwards until you see -1dB. There are many ways to adjust the audio drive level. In some ...

Re: Accuracy re fidelity on/with the TX display while using PS

7300's are the best bang for the buck, bar none. Used ones are now <$1K. You might also consider a 10E, I've seen them for <$700. You won't get full power from the amp, but there's a lot to be said for commonality of operation with your 8000.

1. Follow the guidelines here to ensure that you are "48KHz clean" throughout all of your audio setttings: https://apache-labs.com/community/viewtopic.php?f=13&t=2655 2. Always use DIGU or DIGL (almost always DIGU except for you RTTY types ;) ). This will automatically remove all of th...

Gary, Is it possible that these people are messing with you?

Can't say I've seen it here, Gary. Everything is spot on using an Xtronic coupler on my KPA500, on both my 100D and 8000, using either PowerSDR or Thetis.

Re: Anan 10-E remote operation.

Prem,

Not to my knowledge. I have not tried to use Teamviewer because it has much higher latency than RDP.

Perhaps someone else has done this?

Re: Panadapter & waterfall settings

Gary, I would actually be more suspicious of the power meter. Typical ham radio power meters, even good ones, are not designed to provide accuracy at power levels of 10's of milliwatts, or anywhere less than 1W. Set it all up again. Forward port of the coupler attached to the PS Input port on the ra...

Re: Panadapter & waterfall settings

Gary, While possible, it's very unlikely the coupler is at fault. They are extremely simple and rugged devices, and Dave's design in particular is quite good. Those readings are suspiciously commensurate with you using the wrong port for feedback. At the risk of stating something that is very obviou...

Thanks Scott.... so I learned one thing - it is not as I had hoped or suspected a relative display - rather you are saying its absolute. I'd lobby for it to be made relative as the "tool" as I had envisioned it is to "see" the TX waveform - not know its amplitude (I have that in...

On TX ... why is it that the displayed TX signal is all over the place relative to the vertical magnitude scale? It is not "all over the place" if everything is properly in order in your setup. if the answer is it depends on the attenuator settings well that seems not really a good reason...

Re: Anan 100 12v power rail?

Stu, You have it 100% correct. All relays on the PA/filter board are powered from the Hermes and its on-board 12V regulator. It's a bit odd, to be sure, but you have to remember that the original Hermes and Alex boards pre-date the ANAN series radios, so things got kind of strange in places as Apach...
