HI,

Apache has arranged the repayment by bank transfer.

Hi,

what is the IMD free dynamic range of the Rigol?
How did you rule out that you are not measuring the IMD of the Rigol?

We measured the Orion MK2 boards IMD many years ago (we also found a construction error), the output IMD of a REV 5.2 is partly worse than their measurements without PD, we ...

Hi,

No, nobody here has contacted the police yet, but that would be the first step.

Apache has now made contact, probably from the Abhi itself, as the other mails are blocked by the Hotmail server.
The repayment should now be made by bank transfer, as Apache no longer uses / can no longer use ...

I have not yet heard other people who could not get the goods or money here. But exactly what you need to do something to return the money. PayPal will no longer help me, 2 years have passed since the payment.


then you should search for it in the forum and in groups.io, you will quickly find ...

Hi,

you are not alone, here is also an OM who has about the same procedure with Apache, until today no refund of 1800$...
Here you will probably only get further with lawyer and authorities, we want to try that Paypal Apache freezes the account because of suspicion of fraud.

Perhaps a list should ...

That was my line of thinking. I was just hoping to get the TX state, along with frequency without polling the radio constantly.
Thank you very much !

Ed

Perhaps the function that the radio sends selected CAT data when the frequency or another trigger is changed could be implemented in the ...

With capacitive and resistive coupling, the influence of the terminating impedance on the attenuation must be taken into account.
In my opinion, a loose coupling in conjunction with a resistive ATT is the better solution.
I used the solutions up to 4m, with an attenuation of 50db +/-0.5db

With the Apache HW it is the same as with the 7610/7760, both ADCs have a reference source, and different antennas can also be assigned to the ADCs.
Without the right software the Apache HW can't do more and even that it couldn't, because Apache Labs doesn't have its own software and relies on the ...

of course the two receivers are phase syncronous, they have a reference, two LTC2208, maybe they go for the 2209.

Apache Labs has no diversity, the PowerSDR/Thetis software makes this possible

DPD would also work with other power amplifiers, for this you need the CIV commands of the PW2, which ...

Have you ever tried receiving on a different band?
What is the transmitter doing?
Do you have an RF signal source?

Looks like this week should be the big one. First post in this thread was on May 15th. Two to three weeks for receipt of the upgraded power supplies. And one more week for proper fitment and testing. That is now behind us, so notice of final payment should start being received by all those who pre ...

Don't be so impatient, it will happen in the next 1-2 years.

I have developed a small board for the conversion from BCD to IC-PW1, the PW1 works only via CIV for the band switching.

Hello Richie,

would it be possible to activate the voltage and ampere display for all radios if you want to, like on the Anan 7000 or does this function already exist?

René

Hello,

unfortunately I don't have much time at the moment, QRL, family, house..., all the components are with me, I have put the project in a box for now and will continue it when time allows.

Theoretically, nothing will change in the following stages, because the levels of the main signal will ...

Hi,

is an Amidon T50-6 with 9 turns 0,6 or 0,8mm Cul.
Sweep all filters please, especially the filters from 30m are critical.

Then check if the correct filter was switched, there were firmware versions that did not select the correct filter, you can see the result.

The next thing is, the LPF is ...

Happy Easter!

Are there any news about this IMD thingy?

Hello,

yes, I got my test boards, still waiting for some components, then I try to reproduce this behavior first.
If this succeeds reproducibly, I have made small adapter boards with which I can insert other transformers and attenuators ...

Very Nice!

Here are a couple of pictures of the raw CNC machined Aluminum front panel, this will be black anodized in a brushed finish. Production samples are expected next week from the CM, once approved shipping commences in a few weeks, thank you all for your patience!

My Andromeda also gives first signs of life.

What do you use as coax knob and which buttons?

I found if I turn the VFO too fast the frequency just jumps back and forth, the signals from the encoder look ok, I think the 600imp/u is too much, I ordered a 100 impulse type.

The rest is still in ...

Laurence, thank you so much.

The divider of 8 also works for me, I used a 600imp/u.
Now it goes to the rest.

how i set the increment divisor for the Main VFO?

the code...

void MakeEncoderIncrementMessage(void)
{
int Result;

Result = GVFOEncoderDivisor*10 + GEncoderDivisor; // mmn
MakeCATMessageNumeric(eZZZX,Result);
}


//
// handle CAT commands with numerical parameters
//
void ...

Kjell, you are of course right, it is 18db gain, I had already changed it today at noon.

to your test, have you measured a test board with the Gali51+? so in pushpull, I'm interested in the results of that.

To the transverter, you could feed back the IF signal by PAD, on mine the transverter ...

in my wiring diagram Gali 51+ are installed

the GALI51+ have 18-20db gain in the HF range, so the signal must be at most -10dbm to reach the 1db compression point.

Assuming that the DAC brings 0-3dbm level, you need round a 10db ATT PAD between DAC and MMIC amplifier if you don't want to push the Step ATT to the limit.

So you have about ...

Thank you very much for all the replies.

the attenuator must be about 5-6db

As long as PD is not in the HW, the goal for me is to have a clean RF chain, intentionally "mismatching" a stage is a very poor solution and has the charm of tinkering, the clean solution would be a fixed ATT at the input ...

Is T9 also backwards?

I would think so, yes


@Mark
this will be the explanation for the behavior, I will try to reproduce it on the test board, the material is ordered

therefore I suspect a 1:1 configuration, because pin 5 is not grounded (ADT wiring not schematic of Apache)
Therefore I can also measure half inductance between 4-5 and 5-6.

I have designed test boards which are being manufactured to find the fault, I don't want to test on the Orion board, they are ...

Hello,

on my MK2 board pin 2 are grounded, at least according to the multimeter.

I checked the inductance, PIN1+3 = 34µH (1+2 II 2+3 ==n.c.), 4+5 II 5+6 ==17,4µH.

I wonder what happens when they are "correctly" installed, can it be that the gain increases sharply, which leads to overdriving the ...

Hello,

I have checked the IMD3 on two of my Orion MK2 boards, what i saw does not look good
On the search for the cause I landed at the pre amp, at the "primary winding" the IMD3 is ok (DAC out), see picture 1, on the secondary side of T2 is suddenly IMD3 present, see picture 2.
T2 also has 10db ...
