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 not ...

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. These...

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! Andromeda_machined_1.jpg A...

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 developm...

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 HandleCATCommandNumParam(ECAT...

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 output ...

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 +8dbm...

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 th...

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 overdrivin...

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 ha...

Hi, I started to assemble the boards yesterday, what kind of encoder for the VFO are you using, the small one has 120 pulses, the big one I would like to take also has 100 or 200 pulses to choose from. Then I'm looking for the RJ45 socket, in Germany only at Digikey to get, but then post 1120 pieces...

That is a Hermes and Angelia problem. It does not occur on the Orion or Orion MKII boards. Hi, I just wanted to say in relation to "Mystic", and I meant with Angelia not the exchange of the fuse, but the installed power supply in the 100D, which is too weak for P2 and the 3.3V rail is alr...

Hi, what WU2O writes I have experienced with my Angelia-board. It was always claimed that it is due to the firmware, I have found out during my experiments that the power supply of the Anan 100D for Angelia +P2 is too weak, Angelia needs more current, the external voltage board brings too little cur...

I have done this to avoid new problems.


The change of the firmware brought a change of behaviour, but to speak of an improvement?

My radios are found quickly.

Hi, have you ever used a high quality LAN cable? I have had radio failures before, this was due to a simple LAN cable. On a radio (7000DLE) I also had to replace the NET TRX chip, which had temperature problems like yours. The cause was probably a non-soldered thermal pad under the chip. Meanwhile I...

Both devices contain the same SDR board, both also have the 16bit DAC + step attenuator

Nice to read that it continues.

Where can I download the current version, the link in the start post does not lead to the target.

edit:
thanks, found!

Hi,

I once measured my Orion MK2.
The PDF is in German but the pictures speak for themselves.

Your board seems to be ok.

I could transfer the fpd to CAD.

I think that you will end up with 70-80€ per front panel from Schaeffer, PCB from Fischer cost arount 40€/piece with production of three PCB´s or 22€/piece for production of ten

Hello,

...I would be there...

then they end up like Flexradio -> no news in the software,

the CUSDR project could be taken further

with a double click on the ATT font you can switch between Step ATT and old ATT, this function is old

Hello, who writes the firmware for Angelia? Do you have the sources of the latest firmware somewhere? I want to try to build in the band filter control of OrionII, so that you have a separate RX filter for both receivers, like on the Orion MK2. Maybe the manufacturer of the firmware could give me so...

Hi there, I had a similar problem with my Orion MKII card, the Micrel ksz9021rl ethernet controller was broken. Excessive heat exposure over a long period of time is suspected. There was a broken TX channel on my board, but it still worked when it was extremely cooling. After the replacement, I inst...

Hello,

have you ever removed the entire database folder?
If not, I would do that first.
