IDX-PRO+VDI

If you don't like 33nf to be on the board just placed in searching coil, simple. That's doesn't mean that pcb will not work properly. You can see in my YouTube channel how it's work

I made this pcb and it working fine. Mazixx is funny what you saying

Yes, the board is 2-layer, but it has one minus, it won't work very well in IDX and that's because the 33nf capacitor in RX has no place for it, it has to be in the coil, my justification for tuning the coil is that one capacitor is not enough to obtain the desired frequency, this is just my opinion

Is there a parts list?VDI,LCD

Who have this pcb layout can you share

I have not seen this PCB before. It looks to be 2-layers. If this is true, try searching with the keywords "2 layers" "2024". Perhaps PCBs manufacturers websites have it.

The 950 is a concentric and they tend to be very immune to thermal shifts. But try another coil just to make sure.

Good evening Mr. Carl, on this metal Idx Pro I have always used an original blue max 950, and I have never tried to replace it with another coil, but I will try immediately. Thanks for his contributions, always welcome.

dgm, post a pic of the coil. Have you tried another coil?

Hello, the head calibration is probably slipping due to the heating of the epox. =epoxy resin is not necessarily the culprit, thermal expansion of the head.....
Check the head.
On a sunny day put it on the ground and make a shadow on it, a piece of cardboard 10 cm above the coil, turn on the machine and check the efficiency, remove the cardboard, wait 15 minutes and check again.

Good evening, I have a question to ask the Gurus of the forum, I have an IDX pro assembled about 8 years ago on an ex silver dog circuit, it works great, but only in the autumn winter and spring period, in summer when it is hot it reduces the its potential by half. I thought that some component such as a capacitor could change its capacity as the temperature changed. I tried several times to replace capacitors, but I didn't get any results. Where do you think I could find the faulty component? Thanks for your reply.

You will need to troubleshoot with an oscope and a heat gun. Start with the TX, make sure it is not collapsing at high temp. Then look at the target strengths of the X, R, & G channels at cool and hot. And so on.

Hi all friends, I am trying to design this circuit with 2 layers, all the jumpers are removed and it should perform much better.

[ASENA1400]

that's great
