Followers of Jason NT7S’ blog “Ripples In The Ether” will know that he has been experimenting with the Si5351 chip. This little $1.50 (or cheaper) device is a PLL clock generator which provides 3 independently programmable outputs from 8KHz to 160MHz. While it’s phase noise is not quite as good as the Si570 (the chip […]
Just a quick post to mention that Jason NT7S has developed what looks like a neat little 40M receiver kit, the CRX1. It is VXO controlled, covers about 7030 – 7034KHz, and comes with muting, transmit/receive switching and user-enabled sidetone, as well as a port for connecting an external VFO. It sounds like a great […]
I made my first ever QSO with the CC1 beta a week or so ago. It was with Jason NT7S (the designer of the CC1 and proprietor of Etherkit) and on top of that, it was the first ever CC1 to CC1 QSO. Very exciting! I was hoping to have been the first ever QSO […]
About a year and a half ago, I posted that I had completed the first beta version of the Etherkit CC-Series QRP CW Transceiver. It was a neat little rig, with low RX power consumption (of the order of 50mA – a bit less, I think), full DDS VFO coverage of any one HF band, […]
When 4SQRP brought out a version of the David Cripe NM0S-designed Hi-Per-Mite Filter, I noticed that it could be configured to give up to 50dB of gain. Like many others, I’m sure, my next thought was that it would make the process of building a simple direct conversion receiver even simpler. I decided that at some point, […]
I did make some progress on the DSB80 a couple of weeks ago and then put the project aside. I became a bit sidetracked by other things, some of them non-radio, so want to provide an update in case the DSB80 project gets shelved for a while. I received a wonderful e-mail from Frank Ogden […]
etherkit’s OpenBeacon is the first kit to be offered by proprietor Jason NT7S and I think it’s a good one for him to open up with. Sure, it’s not the first QRSS transmitter kit on the market but unless I’m missing something (and I don’t believe that I am) it is the most versatile one […]
Phew – quite a headline there. I suppose if I were a more organized blogger, I’d break this into several different topics and get several blog-posts out of it. However, I’d like to get it all out of the way, and get this info imparted to you in one fell swoop, so here goes. After […]
I remember John AE5X blogging a while ago now about a cheap capacitance meter that read the capacitance values out in Morse code. Some time later, on searching around online, I found a cool-looking and cheap meter on Sparkfun. John blogged about this meter too. More recently, anticipating an upcoming need for such a device, […]
In the last post I reported that I had made contact with the T32C team on 40M with 4W from my Norcal 2N2/40, and also with 4W on 80M from my Tut80. The goal was to make a contact with them on every band I have capability for here, which meant just one more band […]
