Congrats on your great finds! DSP noise reduction plays well with the TR7. I have a JPS NIR-12 and a ClearSpeech base. They complement each other nicely. Some tasks are better with one or the other.

Here in Silicon Valley, we have been ham-swap-less for a couple of years. First COVID killed it, then the venue ( Fry's Electronics ) went *poof*. Local clubs just managed to restart it last month.

Be sure you ship the speaker cabinet and P/S in separate boxes as stated in the manual. If you ship them as a unit the weight of the P/S will severely damage the speaker cabinet. A seller disregarded

I can send it to you, BUT.. It is totally un-supported. I am not sure I understand it at this point. It is a two part system, one in the rx, one in the tx, talking over a one wire bus. I posted the

Hi Gary Where can I find the source code for the FS-5B version? T3 Gilles Gilles F1BFU since 1969 GQRPClub 15889 QRP ARCI 16979 ? Chacun a raison de son propre point de vue, mais il n’est pas

Here's the pictures. Don't know how much shipping would be but I get an estimate. Ron WB4OQL Clyde, NC wrote:

You want 16MHz.. Like I said in a previous post, it MAY be possible to change the Arduino to 20MHz but you don't really want the hassle. There are a lot of 20MHz TCXOs available but 16MHz is rare. 73,

Gary Yes some have a hole that allows access to fine tuning. it can be supplied for the frequency of 16 mHz or it is necessary to upgrade the frequency of the Nano from 16 to 20 mHz. 73 Gilles F1BFU

Gilles, The main reason is because I have a better solution for my project.? See photo, the small silver device in the lower left corner under the 25K trimpot. There hasn't been much interest in the

Hi Ron and All, Ron, I'd be interested in your ac-3 and speaker but, unfortunately,I won't be making the trip to the Hamvention. (My loss, I know!??) Would you be willing to ship? My zip is

Hi Garry Why doesn't your solution use an external clock oscillator with a 16mHz OCXO like this features are Specification: Operating voltage: + 5V dc / +/- 5% Operating current: 20mA (MAX) Output

Peter, See the Files section for $14 Homebrew FS-4B That version has the frequency counter.? I tuses an ATMega internal Timer for the one second gate. The code came from an Arduino library, I didn't

If you have a proper size 24V fan then use it, but don't discount 12V models. They draw very little current and a 27-100 ohm 1/2w resistor in series with the positive lead will run it at whatever

Dave, Forgot to mention I also have a MS4 for sale..I would be willing to make a package deal if your interested. Thanks, Bill N3WM

Hi Gary, Do you have some Arduino code somewhere showing how to use it as a counter? I am also wondering if you would be better off connecting an accurate clock (such as the 1pps on a GPS module or

Good news Sean. Thanks for letting me know. I'd still open the RV-4C box and check out some of those larger resistors as well, if you have not yet done that. Enjoy the TR-4Cw/RV-4C combo! 73 Peter

Hi Dave, I have a spare AC4 that needs recapping that I will sell….it does not work. Price is $125 + shipping from 23323 (Chesapeake, Va) 73’s Bill N3WM

David, I am interested in the AC3 & MS4 if they are still available. What are you asking for the pair? I will also be at Hamvention hosting at booth 1003 - 1004. Dave KC3AM

Peter, not only did the De-oxit fix the audio output issue, it brought back the VFO lamp! Thank you ! 73 Sean/KK6BEB [email protected]> wrote:

Barry, I have thought about that... They can run up to 20MHz but you have to burn in another bootloader so you can still load over USB. Might not be that hard but my eyes started glazing over a few
