Both variations of HaliKey allow you to connect your morse code paddles, or PTT switch, to a computer for remote operation: Some software on your computer expects a serial… Read More »The Split Future of HaliKey: MIDI and Serial
I just discovered that I’ve shipped about 40 EggNOGS kits, all 436MHz, with phasing boards that were fabricated incorrectly. Two holes were plated that weren’t supposed to be. It can cause a dead-short at the feed point and/or after the common mode current choke. Unfortunately, I have no way of knowing who got the bad boards. I have a 436MHz… Read More »EggNOGS Partial Recall: 436MHz kits

Everything you never realized you wanted to know about Audio Isolation Transformers. Full details: https://github.com/open-headset-interconnect-standard/collected-data/tree/main/Audio%20Transformers Summary: I had a customer ask about the frequency response of the OHIS hardware I make. “I, uhh… don’t know? I know what I designed it to, and it SOUNDS fine to me… But I’ve never measured it!” Ok, let’s do this thing. The most… Read More »Audio Isolation Transformers
It launched! Yay! Party! Victory Arms! \o/ I’ve been heads down this week really trying to get EggNOGS out on the market. I just clicked the “Make it Public” button!
Hamvention 2024 is in the books! It was REALLY GOOD for Halibut Electronics. We sold out of Common Mode Current Choke Test Rig kits, Contesting Consoles, and Radio Pro adapters. (Granted, I brought a limited number of them.) Several folks ordered things that I’ll have to ship to them when I get home. More importantly, I met A TON of… Read More »Hamvention 2024
Hey all! Check out this video from the ARRL, showing a little in-house Common Mode Current Choke building competition they posted a couple months ago: They have people of various experience levels, from not-a-ham(-yet) to veteran Amateur Extra, build different designs of common mode current chokes. Then (starting at about 5:45 into the video) they hook up their chokes to… Read More »CMCC Test Rig, used in ARRL Labs?!
I just launched the Halibut Electronics Broadcast Interference (BCI) Filter for VHF/UHF. It’s designed to prevent strong AM broadcast signals from blowing out the front-end of wide band receivers that have little or no pre-selection, such as inexpensive SDRs. There are many BCI filters availble, but all the ones I could find were designed for HF, and performed very poorly… Read More »Power handling of BCI Filter for VHF/UHF
Check out this wonderful blog post by W0DHZ, Dale, showing how he built an HHI Contesting Console, HHI Radio Pro, and two HHI User Pros into a portable setup for use as a 2-person POTA rig. I mean, just look at this beautiful build! Dale’s blog post includes the STL files for the 3D printed case to hold the Radio… Read More »Contesting Console for 2 Person POTA
Friend and listener to the Ham Radio Workbench podcast, James AE8JF, wanted to make his own OHIS Radio Adapter for his IC-9700. So he did some research and noticed a couple things: (*) The only exception being the Vcc power source, which is optional in the OHIS spec. This means he could build an entirely passive OHIS Radio Adapter, that’s… Read More »Simple OHIS Radio Adapter for Icom Radios
