Same here Tom. I lived near Huntsville when I was first licensed, WN4CCA. I sent off for a NASA technical bulletin – “Telemetry”. Latest in high tech. Interviewed at IBM Huntsville, they showed

Eric, i have a couple of display protection boards left when you do your JackAl display de n2aie vince

I would appreciate assistance with the 40 please. After triple checking connections, I fired up. The display was blocks which adjusted with the pot on the Rad board. It was drawing 140ma on idle

Cool site. Fun to look once again, in the context of the era of Heathkit kits and the early space race technology, the electronic designs I poured over learning electronics design. Then think of now,

Hi, I found some reviews of the bitx20a. Did not find a schematic, yet. However, I found this CW transceiver designed by Dan Tayloe that has a couple of mosfets to cut off the RF to the receiver

If you guys can locate, look for the bitx20a manual. It has a Tayloe T/R switching system. The other mod will be to keep the lpf relays powered up. The heaviest lifting is what we can do to avoid the

Interesting, I was looking around at sites that featured old Heathkit photos and product information. Found this link. Looks like someone is reviving Heathkit in Santa Cruz California. Maybe a

In my experience, yes. I haven't used Eneloops, but IKEA Ladda (supposedly rebadged Eneloops) and Amazon rechargeable AA will power it for a short time, but quickly go too low, resulting in

Lets see, the ubitx was advanced because many inexpensive rigs only do cw. Funny thing I mostly have done cw with the ubitx, but the early qsos were ssb. I imagine somewhere there is a ubitx that

Hi Rob, No problems. Ok for the regulator, that should work just fine. Regarding the place to insert the Teensy, here are my thoughts: If you have an AGC then before the volume control as you

My new site adress : https://www.qsl.net/py2ohh/ the old was hacked ... and I lost the links ... 73 from py2ohh miguel

Can you verify that after you get the message that the setting has been saved that you completely power down the Raduino (disconnect any USB cable and power down the board)? The new value does not

Well, I could probably hijack the front end of the HW 100 and use it for exactly that purpose!

John, Thank you very much for the very thorough reply. Mostly (!) very encouraging, as I think this will save me a lot of thinking and worrying about ground loops in my RX audio and transformers and

Hello Rob, In my experience ground loops on transceiver to CPU based units are only an issue in TX when using "longer" wires. For reference I used a second Arduino Nano mounted inside the uBitx and

Brings back memory's of when I was first interested in Ham radio. The description of that radio/transmitter with dual conversion and crystal filters was something that made me want that rig. I did not

All pre-orders have been shipped and I have 12 kits left https://shop.kit-projects.com/index.php?route=product/product&product_id=119%27A=0 More will be ordered as time goes on so if they are sold

In a past life, I did a lot of graphics design, mostly using Adobe Illustrator and Photoshop. I'd like to take a stab at a custom uBitx UI for the Nextion 5" and I'm wondering what, if any graphics
