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

Hello Dave, Chas, and the group. From the schematic of the Hilltopper30 you sent me and I posted to the files section: C1 = 47pf C0G C2 = 220pf C0G C3 = 68pf C0G L1 = 5.6uh Mouser 542-78F5R6J-RC L2 =

Hello, i have been looking at getting some hardware for chip programming these wonderful radio chip sets (i am a programmer by heart!). I have already built a HT20 and ordered a HT40. Any suggestions

I want to thank all who worked to bring out the 40m kit. It amazes me the performance from my completed project. At 12 volts, it puts out a bit more than 5 watts, the receiver is sweet, and the keyer

I am assembling my Hilltopper 40 kit. The small inductors don't seem right. L1 = Brown Black (black gold). Alright for this one. L2 = Blue Gray (per manual) I have an inductor that orange orange gold

I just finished my Hilltopper 20 and it works very nicely. However, the sidetone is really loud. I remember seeing something about reducing the sidetone on the list, but forgot where to look for that

Just about got mine ready ... also got it at OzarkCon. A few more components and then the hardware. Work on it twice a month at our builders club meeting at Joe Porter’s (W0MQY) house. Hope mine comes

Finally got around to building the Hilltopper 20 that I purchased at the 2018 OzarkCon. Put it on the air today and first QSO was with Sweden! Other station gave me a 577 report with the same on my en

I am just curious about the supply voltage tolerance for the radio. I am guessing 9V to 15V, with corresponding variation in output power. Has anyone tested performance on voltages other than 12V? 72,

Does anyone know if a decision has been made by the powers to be at the 4sqrp group to offer 30m or 40m versions of the Hilltopper Kits? If so, approximately when they might be coming? Thanks es 72 -
