Wasn't me who bought him into the light, it was the eejit..

Thanks for the flowers, asshole. You don't know when to STFU, do you?

While I am here, for the record, The Lurker contacted me and he volunteered his TX and all the information.

I was going to purchase a Transmitter from Stretchyman, but I'm now going to bow out after seeing several posts including this thread.

Aftersales service plays a huge part in my purchase, & as what I've read here is pretty grim I'll be looking elsewhere.

Many thanks for the heads up.

Thanks...!

Even the low power versions are a different design to the 40W but hey if folk want to believe the Charlie TW*T good luck to them..

Things have improved considerably.

I'm not going to slog through the above, but I can tell you  that I got excellent support after the sale in helping me complete my 40M AM transmitter kit.

What is there to not believe?

You, yourself, are admitting right here (and in previous posts) that you had problems with your 40W TX. You improved it by changing the power sequencing. I wrote up 36 pages in two documents detailing the issues and why they are design flaws. You even thanked me for the first report at the time. I took a different approach to improving it but that's OK; I just didn't want to change the sequencing and make it harder for people to modify.

You admitted that you have a frequency shift issue with your 10 W (I guess) crystal controlled transmitters and believe it to be the result of some specious claim that crystals oscillators axiomatically randomly drifted 1 KHz or more since the days when then they were first invented ~100 years ago, which is completely ridiculous and I explained why. I suggested that the frequency shift issue is more likely that the crystal is dissipating too much power and provided a link to technical articles suggesting the same. This was met by no counter evidence from you.

If this wasn't enough, we have the folks that chimed in here and privately to me that told me that they had the same issue with your 40W TX. The frequency shift issue is further validated every time certain stations go on the air.

Both of these issues could have been found if you had spent a modicum of time actually examining them in the prototype stage before you shipped any. It's fairly basic in the professional world to evaluate your product in the customer use case. In this case, it means actually turning the TX on and leaving it on for an hour or two and make sure that it doesn't break, it doesn't drift, the power output stays within expectations, power dissipation stays within expectations, and on and on. It's also pretty normal in this customer use case to turn the transmitter on and off each time you use it and had you done that, you no doubt would have broken a transmitter, which should have caused you to investigate. Even if that somehow did not turn up anything, when the evidence was mounting that normal customer use was breaking the the 40W TX, I showed that you were just sweeping it under the rug and blaming the user instead of actually addressing it. It was only after I wrote up my expos that you came clean on it.

So, again, what is there to not believe?

It is perhaps no wonder that, with your behavior as it is, that Chris banned you from advertising on this forum. He didn't want to be a part of it. (Side note: I suggest that your signature and Andr posting the video above should also be considered advertising.)

Thank you for your educated, thoughtful and enlightening answer that clears up all questions that anyone on here might have about you and your cheap little fraudulent "work".

When my old model worked, it performed super great. He offered to fix it too but I declined. He's capable of making a better design.  I bet you can trust him if he says he made the design better it.

Take a look at the timeline. I was letting things lie for a long, long time. I've moved on to other things but he brought it up again, not me. Your complaint is not with me. If there ever was an "own goal" (as they say in the UK) here, this is it.

Also, I didn't see anyone complain when he brought it up but the minute I reply with actual facts to set the record straight, I'm mobbed by his fanboys and apparently become the aggressor, somehow. It's good that you've all gotten your biases out in the open.
