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

Gm Group The HILLTOPPER 20 is back in stock! Thanks for you patience. 72 Johnny AC0BQ -- Check out the 4SQRP website at 4sqrp.com

Good evening Group We have experienced several delays from our suppliers as we re-kit the Hilltopper kits. We’re sorry for the delays, but we’re doinv the best we can. On the bright side, we will be r

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 -

(you read that right) I used my Hilltopper 40 in yesterday's NA CW activity to the tune of 42 QSOs. That was with the low ground-plane antenna and a 1.3 AH Li-Ion battery. What a hoot! 73- Dave, K1SWL

Good afternoon i am pleased to announce that we have the Hilltopper 20 kits back in stock. All kits have been upgraded to Rev 2, thanks to Dave Benson K1SWL. Thanks 72 Johnny AC0BQ

John- (still inhaling the first cup of coffee here) DigiKey also carries the bootloaded version. At least with them, searching on 'Arduino' ensures that you're getting the right version. To my knowled

Well, installing my newly programmed chip was a spectacular failure. I tried to change the following parameters: Side tone, offset, and timeout for tuning. I ended up 50 KHz off frequency on transmit,

I have to admit that the libraries and error messages that occur with Arduinos I find baffling. I am trying to compile my own code for the Hilltopper and below is the error set I get. I think some of

I must say that the radio did very well today in the field. I still don't know how sensitive it really is, but I have an Elecraft signal generator at home that I can try some attenuation levels. I bri

Dave Benson, you'll be glad to know that the implementation of the keyer in the Hilltopper is far superior to that of the QCX. While the QCX is a fine radio, the keyer has a tendency to stumble period

I am thinking about purchasing the hill topper kit and am wondering what the maximum allowable operating voltage is. I have a MTR3 and a ATS3 both of which say to limit the operating voltage to 12 vol

I want to publicly thank Troy for his help. It looks like I may have a working uP now. It was a matter of conflicting libraries between an old IDE and the new one. I started the build today and have a

In the instructions it says the firmware is available in the files section. Just curious when that will be released. Thanks, Troy KF7SEY

Well i got my kit yesterday and between last night and this morning i have completed it an done all the alignment procedures. This is a great kit with great instructions. Im only having one issue and

Hello, I have read in the manual that supports the built-in keyer iambic mode A. Is it possible to change the keyer to mode B? Thanks & Vy 73 Martin DH3FR

Just bought a hill-topper. Super excited to get started on it. Just curious how long shipping takes? Thinking about using it for the skeeter hunt qrp in aug. Thanks, Troy KF7SEY

Who can help me with problem with Hill topper? tnx larry
