(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

Hi Folks building a hilltopper and it is dead after completion, this is one of the first run kits, seems not to have a program loaded, power up and Nothing No TX only hiss in head set. sure could use

I notice that the gain on the Hilltopper is mostly useful in the top 25% of the control. Is there a way to balance this out a little? What would happen if a parallel resistor were placed across the fi

test -- 72 WAØITP I love this radio stuff. Back to the bench, Winter is too valuable to waste. www.wa0itp.com www.4sqrp.com

I am measuring about -118 dBm +/-2 here on Rx which is about right for an NE602 input device. I do like the audio gain turned up. I am also measuring output power at about 3.5W which is close enough.

The Hilltopper is now on the 4SQRP kits page. Please be patient with your order since I am starting up both if the new kits announced at OzarkCon 2018. It might take me a day or two to catch up to the
