Went to the Chinese site and notice they are selling your book for $2.21. ?I suspect China is not sending you a royalty check. ? v/r Fred W4JLE ?

Subject: Re: [BITX20] Possible PA low output problem. ? If thinking about getting a scope, you could do far worse than investing a little time to read up on this blog I bought a Tekway DST1102B back in 2011 and followed the instructions on the blog to get from 100 MHz to 200 MHz just by software change. I felt very pleased with myself until I later discovered that I could have achieved very similar results? by performing the software conversion on the still cheaper 60 MHz version. Still, 7 years on, I'm happy with my scope. ? On 6/02/2017 6:44 AM, John Smith via Groups.Io wrote: I am going to keep working at it until I am sure it is working as good as it can. And do as many hacks as the hardware will stand. And learn all about it in the process. Actually work for a contact, and achieve it. This is what I like most about amateur radio. When I bought a MFJ-9240 cw transceiver I got board with it because there is no work involved with a boxed radio. I know I am getting behind with operating skills. But if I can bring a dead boxed radio radio back to life, I'll have a nice zombie station. And still have the money to spend on something that can't be made, or repaired. And I got the patience to do it. Now, how helpful would an oscilloscope be at this point with the Bitx 40? I haven't needed it yet. I have only been into electronics 2+ years, and amateur radio 1+ year. And I will be checking into those easy to make tools Jerry has been talking about. For those who wonder about the power supply. Power is what I started with, and I have plenty of beefy options, linear and switching regulators, and fuses. What I am using now is from a lcd monitor. A switching power adapter at 12.6V 4A that doesn't dip under load. And no line noise at these frequencies.? Yea, I can't recommend this product for any other beginner. Just hams who already have working radios and like to tinker.
