Okay,. So I rechecked all the windings and all the solder joints, they all seem to be good to me. No shorts or anything thing like that. Upon diagnosing I did notice I am getting power out to the ante

Okay,. So after arguing with the son to do his school work for weeks I finally got around to working on the qcx+. I went ahead and purchased all new BS170 & MPS751 + the IC2. From my power supply Im g

Thanks Ron, I'll give that a go. I'm not to familiar with this type of circuitry but I was leaning on Q6. I'll probably just replace the whole cluster. Yeah, I meant to say menu 9 for the test setting

#qcx40

Thanks Ron for the info, I hope I don't make two many typos, it's about 3am. So apparently the voltages differ from when it's in the test equipment mode (9.2) than when it's in the normal state- I fig

Sorry about not getting into much detail about the components, I was about half asleep sending that. I was using the built in DVM on the qcx+ to do the readings, but this time I used my handheld meter

This group has been a lifesaver,,,,. Ok, I'm having a no rf power issue. I don't have any fancy equipment to do an accurate diagnosis, I'm using a DVM and the onboard testing equipment. First off my P

Here's another one..... I have my qcx+ built in a different enclosure then what it's built for. Everything The build went ok, everything powers on like it should. The BPF adjustment was in specs, but

Question?? What would you prefer to test for rf power. Oscilloscope or just a regular swr/rf meter. I've never owned one so I was just wondering which of the two is more accurate. I know the scope can

Hopefully I answered my own question. Maybe I should read the manual a little better..... So on the modifications page, JP15 & JP16 are the +12v and the ground. Basically I should run the ground as us

I have a question maybe someone has run into. I'm building a 40m qcx+ in a different enclosure that's designed for this machine. My original 40m qcx has a page in the manual where it shows you the dia

Thanks for the replys The question was brought up in the past so I was able to figure it out pretty quick. Luckily I had about 200 10K's on hand. Now just to decide on an enclusure and finish the buil

#40m #manual

I have a question about the installation manual, hopefully some others have run into this issue. On page 80 (3.59) of the manual, it says to install the 10K resistor R46. I didn't have one in the cont

#40m #manual

Could the update be done with a cpu like the raspberry pi, or orange pi? I have quite a few of those, but I currently don't have an Arduino

#firmware #qcx40

I have a quick question about the firmware updates. I have the version 1.00 on my 40m qcx. Would it be beneficial to update it or does it really need it? I don't see any issues with the device as it i

Thanks everyone for the replys and opinions, I'll definitely take them all in to consideration. Yeah- the day I passed my tech liscense I purchased a used Yaesu mobile all mode hf uhf vhf transceiver.

Being im only liscensed as a technician, I know that I'm allocated to only certain frequencies I can use in the hf bands. (Hopefully not for too long, working on the general soon). Has any one ever ex

I have a quick question about the onboard testing modes (voltage & rf). How accurate do they seem & how do I access them?

I haven't heard of that group before, I'll have to go and check it out, when I get home. Thanks for the info...

#qcx40

Well the good thing is that it's operational. I went to both the RBN & Websdr and both picked up on a signal. On the few that picked up, they were around 500-600 miles away. I'm guessing that's not to

#qcx40

I'm going to try the RBN later on this evening, and see what happens. Hopefully I can get some results on this issue. If not I'll go through the installation again to see if I fumbled something around
