Good to see you manged to get it all sorted, and getting results even better than what i got. You thd+n is somewhat higher than thd, worthwhile checking all your connections for interference

@zoelong6021 cheers for the inspirational push, I enjoy the challenges. The noise level is higher than I hoped, At a guess it may be to do with the Realtek ALC 892 driver for the on board sound, its HD sound but HD as in 720P and not HD as in 1080P. My urge is to try out the Focusrite just to see the difference, have you tried it or know what its loopback result looks like?

I'll bet it's very satisfying to build that voltage probe and get an order of magnitude better look at your sound floor when measuring total harmonic distortion and noise. It's all a bit over my head but it's cool to see you enjoy the victory of overcoming obstacles.

It's great fun mixed with occasional frustration and constant learning, just like building and flying drones. I see your RSSI is not quite sorted yet, I expect it is a challenge, else it would have been resolved already. I was described recently as tenacious by someone. First, not knowing what it meant, I thought it as an insult. After looking it up I realised it is probably my greatest strength in overcoming the obstacles. I know you can to.

Tenacious is always a compliment in my opinion. And accurate from what I know of you through our years of correspondence. I once had someone say "I'll bet you're hard to kill". That might be my best compliment to date. Yeah the RSSI issue... it might be that my RC control antennas sit too close to the battery. I've been ignoring the RSSI reading though because my link quality numbers are quite good and I've never had a link quality issue. I think I'll remove the RSSI readout from the OSD lol. My distance barrier at the moment is video transmission and reception. I can go about a mile before video break up. Sometimes more if I keep the directional patch antenna aimed carefully. It hasn't been a problem because I don't really long for more distance in the type of flying I've been doing. I may invest in better antennas (possibly a different style) if I intend to routinely fly beyond a mile. 📡

@@Sonic_Ox the positioning of your antennas would effect the link quality. The RSSI may be a scaling issue, its worth a look. Nice to get the platform perfect. VTX RX antennas are important and a good overall investment.

You are right Elecifun. I really need to come up with a better solution for RC control antenna placement. As for the VTX/VRX antennas, they're a bit frustrating because these ARE quality, after market antenna that weren't cheap. Also, the VTX itself is advertised as a long range transmitter capable of 800mW etc etc 😑 I'm not unhappy with my results so far and am still having a great deal of fun chasing the "ideal" platform. The high paced changes in technology keep the hobby fresh in my view but come at a cost 💰 lol.

@@Elecifun Well if you can do that you can build speakers. I mean think about it for a moment. Can you measure a piece of wood? Yes, I'm sure your more than cable of doing that. Can you cut it square and plumb? Yes, with a drop saw yeah, it's not hard. So really it's just cutting two front pieces. Two back pieces. Four sides all the same length. Two top pieces. Two bottom pieces. Some pieces inside to reinforce the speakers. Then the 🕳 🕳 🕳 holes. Cut a piece of timber the right length. In one end you drill a hole. The other end another bigger hole to mount a router. You bolt the router to the wood. Like this: kzitem.info/news/bejne/tpuJupZsf6GAlHosi=HBUrsg2E540O_GZj The design for the box is already done. So acoustically it's correct for back pressure. The actual cost of the boxes is that bad. The speakers are pretty expensive for 6 speakers 2x 10" or were the 12" not sure. They're the most expensive components. I think they're $600 each. Then you need 4 more. Two tweeters. Two midrange speakers. Then of course is the amp which needs to be powerful to drive them hard enough without blowing them up. Of course you need two cross overs. Some nice gold plated speaker post. And good copper wire. I have some already it's from Germany and its very high quality. So I just need to get some spade lugs and crimp them. Same the other end except they're male plugs into the power amp. That's another story. It would be an exciting project and you could even sell them and build another set. 😁👍 Winner winner chicken dinner bro !

Oh yeah you need some insulation for sound damping. Just get some old pillows and remove the stuffing.

Does ARTA let you calibrate/compensate for the sound card's own frequency response?

No need, only calibrate sound card output and input. frequency response is only whatever device/amp under test.
