The Teensy SDR project is worth doing if you want a complete radio in a box. Ken VA3SK

Hello, I'm definitely enjoying the softrock/tiny-linear combination. I never had a rig with a panadapter before, and it could get addicting. What's not addicting is the forest of little circuit

It's my home project. It started out as a set of items: 1. A Chinese linear amplifier kit. Here's a link: https://www.ebay.com/itm/224081391143 2. An HFsignals.com "Raduino" card, with an Arduino

I was going to say and ask the same thing. The Tiny Linear sounds interesting. Dave KB9GPM

Hi all, As the subject line sez, I am looking for a RXTXv6.2 20m_30m kit built or not. I would also consider a non-working unit as price is kind of an issue for me. If you have one, please reach out

I haven't heard of The Tiny Linear. Do you have a link to it? Dave W2IJL

So - with the help of the Tiny Linear - I made my very first QSO with the Softrock. Being mindful of its sensitivity to ground loops, I installed an optocoupler at the PTT output of the AtTiny. I

Wow - Rocky even does semi-break. It's called "Vox", but you hit the key in CW mode and it transmits. Trying some CQ's on 40M...no answers. 2 watts just isn't much. I wonder if I dare use this

...and this is weird. Just for yuks, I commented out the si570Calibration line in Rocky.ini, by putting a # at the beginning. Restarted Rocky, and it's dead nuts on. Well, about 20Hz off. That's

So - the only software I've found that reasonably transmits with the Softrock is "rocky". It's not fancy, but it fully supports transmit, including a keyer that works with a paddle plugged into the

I just had yet another project fail because of a bad connection to a toroid - where the insulation didn't burn off properly. I've had it. I bought one of those motorized strippers for enameled wire.

I use this... https://james.ahlstrom.name/quisk/

OK, I fixed it. It was transformer T6. One of the leads was not connecting to its circuit board land. Now receive is much improved, and it actually transmits! I am seeing two watts output on 40M.

Cleaning out some odds and ends: I have a M-Audio Audiophile AP192k sound card with the M-Audio break-out cable and two 1/4" male to 3.5mm female (stereo) adapter cables available. It's an older

Good Morning Group, So far no one has showed an interest in the 4 MHz to 8 MHz receiver board detailed below. Being USB powered makes it handy to use and with it's Si570 clock any center frequency

I have a M-Audio Audiophile AP192k sound card with break-out cable available. I bought it second hand, never used it. Since it's an older card, it seems that Win7 drivers are all that's available for
