Gents, I notice from the main page that all Hilltoppers are currently sold out. - Is there a rekit and if so , which bands please ? I seem to remember a price (indic. only) of USD 105 and I am guessin

I finally got around to building my HT-40 kit and have a problem. The receiver works fin and the transmitter puts out a good 5 watts but the sidetone is just a buzz and the keyer is extremely slow, ma

I saw Jim W3BNO's comment about the Hilltopper instructions on the main subgroup. I have a few more items I found while building the 40 meter version. I think the new manual has the same information.

Dear Hilltopper 40 Subgroup: I am a 78-year-old returning amateur licensee having lost my 1968 Extra-Class call (w1dh) earlier this year for failure to renew. With the assistance of ARRL VECs I was re

I have been having fun with the Hilltopper 20, making contacts in US out to 1600 miles (CA). No DX yet but cant wait for the CQWW 'test n Nov. What are your Hilltopper stories? Curt KB5JO

Hi to the group members. I'm Colin, M1BUU, and I've built many QRP transceivers over the years. Several years ago I built an early Hill Top 20. The rig is impressive, however my code sending skills ar

I plan to burn a version of the HT20 arduino code with a start-up freq of 13.555 400. So to verify I can do it, I compiled the current V2.0 code, 20M, used he correct Etherkit 5351a lib and got a good

Is the spot on the board for a 6 pin header, behind the Si5351 board, for programming the Arduino chip? If so, how do I interface this with my Arduino board? It would be nice to be able to program the

I would have loved to been a member of 4sqrp group when it started. But better late than never! I asked the question a few weeks ago and got a positive answer back that they are thinking about it. I a

Am going to see what can do with CQ WW DX 'test this weekend. Historically they all listening hard for QRP n QRPp.

What are the fuse settings for the current code release? I've done a search and not seen any mention of fuse settings. I plan to burn a version for LCD. TNX! Bob WA1EDJ

I don't have my HIlltopper 20 yet but will soon. My long term goal, after it it working minus LCD is to add one. Is the Lloyd WA4EFS code the solution being used these days? From what I can tell it is

I built both 40 & the 20 meter and both function beautifully. I do not have a display on either of them but I would like to see them kitted with one. I would definitely build 2 more Hi Hi. 4SQRP does

First, the radio sounds great and it seems to put out at least 5 watts, but there are a few problems I have encountered. After trying to match the frequency with the Cal jumper in place, the radio is

I vote for it .... 30 is super for CW. I have both the 20 & 40 and enjoy both. Easy kit to build with top notch instructions with a design that’s hard to beat. Jack ..... WD0CFH Pro Jack R. Dock ... H

Please make available a Hilltopper 30. The 20 and 40 are great kits. 30 meters is a great band, so please seriously consider making a Hilltopper kit available for that band. Lee, w0vt, w5drc

I just ordered a 40 meter Hilltopper and have not built my 20 meter version yet! Curt, KB5JO, a friend of mine, keeps telling me how much fun he is having with his 20 meter version. So even though I h

The radio worked when turned on, and no smoke escaped! Alignment was easy as described in the manual. The receiver is fantastic, and am getting 5W output with a 12VDC supply. One question is whether I

Has anyone simulated the HT20 LPF? Using ELSIE to simulate, must be doing something wrong, seeing 3 dB loss at 14 MHz. Of course a deep 60 dB suppression at 25 MHz. I am using 50 ohm input and 50 ohm
