Well, Bill (WB0LXZ) and I spent the evening checking all of the voltages shown on the schematic and they all checked out. It should work but doesn’t. Bill worked some on it with the scope but I can’t

I received an email from Pat Ryan, KJ4DHI asking for information on someone willing to build the Hilltopper40 kit that I just mailed him. I sent him the names and email addresses listed at: http://www

hi folks- Lloyd Milligan- WA4EFS- has added a Serial LCD to his Hilltopper. He was kind enough to share a picture of his setup and modified source code for it. Thanks, Lloyd! Files are attached.. I ha

Gm Group We’re running a President’s sale on the Hilltopper 20 and 40 for this weekend and the following week in honor of the Monday president’s day holiday. Starting tonight the Hilltopper’s will be

I have all but completed my Hilltopper 30 modification. I ran into a small snag, but it was a great learning experience for me. I had no audio in the earbuds, so I set out to troubleshoot the radio. T

OK Dave, I took the chip out of my HT20 and put it in the HT40. Still the same thing so the chip is probably OK. Then I used my general coverage receiver and tuned to 16 MHz to listen for a tone. Ther

I just finished my HT 40 and was starting the alignment process. This is my second build of a HT and my first HT20 was a text book build with no problems. When I plugged in the power the only thing I

I finished my Hilltopper 40 last night. It really looks good. When I put power to it I got a blast of CW as expected. Hitting the paddles brought forth some beautiful code. Power output seems to be mo

...and I show not even a flicker in DC or AC upon turning the 'Tuning' knob ? CC

Guys, I am trying to figure out why my Si5351 output at pin 7 is only DC. In receive ‘mode’, inputting a 7MHz signal from signal generator, what should the SDA and SCL signals be on the Atmega ? CC

Well thanks Charles, your answer go me to thinking, so I hooked the radio up to the indoor shack antenna and low and behold it was working perfectly. So, I started to check some other things and found

Think I took out the finals on my Hilltoppers 20 yesterday. New antenna tuner on an end feed and I held the key down to long trying to tune. Transmitter quit but I still have the receiver. Question: W

So, Atmega flashed OK but radio seemed dead upon alignment. So, I began curve tracing. Seemed to get no IF from the first mixer, although signal in matches the 7Mz+ from signal generator. So I tested

I reported earlier that my HT40 had developed a problem where the receiver had become slow to come up. Dave Benson suggested a cold solder joint, and suggested likely places to check. That led me to Q

In the first two weeks, my Hilltopper40 received fine, but then it began being slow to come up. The frequency readout would happen, but sometimes then there would be no receive sound for a minute, may

Well, first progamming problem......the si5351.h I just downloaded is not compatible fully with the newest Arduino IDE (https://github.com/etherkit/Si5351Arduino#changes-from-v1-to-v2) Arduino: 1.8.8

I would like to change the side tone to 600 hz. I seen in the code where I can do that. What I'm unsure is where to adjust for the offset or if I need too. Anyone done it yet successfully? Thanks, Tro
