Last night I replaced the TIP36C bipolar transistor and reflowed the connection to the power plug with no improvement in the modulation or dimming of the display during SSB modulation. I went rummaging through my radio parts stash and I do have a new L7808CV voltage regulator (U750), a new...

All these little things your folks recommended to me in the spring of 2023 like the good small soldering iron and solder sucker make this stuff a lot less difficult to do. Not easy, but less difficult. Now if only it will somehow magically get this radio working again. I hope so because I like...

Done.

The new TIP36 has the same voltage readings as the one I removed. The marks on the one I removed look like they are from the tip of the probe I was using when measuring the voltage and my aim was a bit off at times. My wife chimed in and said it reminds her of the bathroom. Thank you dear.

I did measure it with two DVMs. One reads to 3 decimal places and the other to two. They gave the same rounded readings. I happen to have a new TIP36CW still in the original packaging from Mouser that I will put in tonight to see what happens. I also have a new L7808CV too but the specs say it...

I started poking around the innards of mine at lunchtime today. Here's what I have for voltages so far. All numbers are with radio at full RF power and into a dummy load using the stock mic set to EL level 36. The power supply is a MegaWatt S-400-12 set to 13.8 volts. Nothing else is running off...

I have finally started down the path of attempting to attain the Technician class license. I'm hoping to be able to find (purchase or free, as long as it's good) a comprehensive but clear study guide that I can access on my tablet. One with lots of good scenarios, the correct solution to the...

I'm happy to state that my homemade tiltable, pulley-assisted, cordless drill powered contraption is still standing tall and proud. It's been through a rough Wisconsin winter and plenty of strong summer storms. It's still dead-simple to lower and raise it myself using nothing more than a 3/8...

Does the QT-60 Pro have the same expanded bands as the new 6666 Pro? The video on the 6666 Pro thread linked to by AudioShockwav shows which jumper you need to move to enable 15 and I think 11 meters.

Thanks for the leads. Hopefully the fuse and fuse holder can be eliminated from the list of suspects since it's now been tried with at least 3 power cords and 3 power supplies at two different locations. I have lineman gloves, a newer multimeter, a clamp meter, a second power supply I used when...

Well, the Q5N2 carcass arrived home today. I gave it a quick test to see if the excitement of the voyage and change of scenery improved its mood at all, but no such luck. SSB modulation is still awful and the display still dims some in line with SSB modulation and RF power level. AM/FM seems to...

So exactly what she does with dresses, purses and shoes. Seems quite fair to me.

Yes, me too. I will have the radio back in my hands on Monday now and I think I will be game to try just about anything the subject matter experts on here think I can reasonably try without a) injuring myself or b) burning down my humble home or c) not having to invest a bunch of money in...

Nice! I think that's what I'm looking at buying to replace my Q5N2 if I still can't find anyone to repair it.

I'm still hopeful the radio is repairable once I find the right tech that will take a look at it. Better for the radio to remain in use than end up in a landfill somewhere, as long as it makes financial sense to fix it rather than replace it.

I love reading about these types of repairs. Lots in it for me to learn. And now I know where to send my flaky Anytone Q5N2 for some magical recovery! :)

I agree, but then again I always like second opinions. Last year when I was trying to find someone to help me out with a self-inflicted issue I was having with a different Anytone I had, I had zero success finding anyone that would agree to look at it. It was either they don't service this type...

There's a real BC lad, full of truth. ;) This is coming from a lad that was born and raised in southwestern Ontario but somehow ended up in the USA. :) My aunt and cousins all live in Vancouver and Victoria. To me, no assembly line is perfect and deviations are bound to occur. At least for...

It's no big secret I am referring to Scott's Radios. I have purchased 3 radios and a bunch of other stuff from him. In my eyes, he's A+, what a vendor should be and I plan on continuing to use his services. The main reason I did not bother initially contacting him is because of these statements...

Yup, I did sent an email both to the vendor and to ken6833@qxdz.cn, whom I am told has something to do with Anytone. I am not looking to blame anyone for anything. Stuff happens, it's just this time it caught me off guard because I have really been behaving myself and taking good care of all my...
