Randell, Running up on the increased inverse complexity of convenience, time to start monitoring power rails? Not being off the shelf plug ins, can’t just add up published specs. You are having way

Searching for the word "error" in your listing shows that it's having trouble with the si570 library. Could be a difference between Farhan's version of the library (he coded that several years ago)

afterall it is easy to compute the inductance of coil with 39pF cap in parallel to give a centre frequency of 14.1 (for 20m band range assuming 40 to 14.2. I use * mini ring core calculator where in

Rather than the duinovox I found a simpler circuit for interfacing data. It consists of 3 small audio transformers (got 10 for a little over $1, a couple of 1N4148 diodes and a 2n7000. I won a cheap

Doug Hendrick's recently published a dropin pcb replacement for the 42if123. He was learning how to make boards, and this was his project. He documented it in the qrp-tech files area, under KI6DS.

There was quite a bit of interest in this over in the FB group, so thought I would consolidate and add here. The project is call the "duinovox" by KB9RLW. I built this very simple, low cost circuit

Hi all, I'm puzzling with the Sweeperino. After many hours of trying I cannot make it working. I took the Sweeperino software from the Razzies website

Dex, I find if I reply on Eudora without trimming the trailing text, the groups.io strips the whole thing. If I trim below the signature and remove the dah-di-dah etc.. terminator, then the whole

I am with you Jerry! Without the relevant lines quoted, it becomes impossible to know to whom or what that reply is about unless I read on the web. Mostly I ignore these mails. Raj

I am using the schematic from: http://www.phonestack.com/farhan/ubitx/ubitx.html ( http://www.phonestack.com/farhan/ubitx/ubitx.html )

Here's the post about replacing the LC BFP wih a crystal filter: ?/g/BITX20/message/30538 ( /g/BITX20/message/30538 ) I remember that one. Don't remember any mention

Added another accessory board to the rig. Built up the duinovox by KB9RLW. It works great for FT8 even with the bodged wiring for testing. The VOX is cheap and easy to build.? and the board plugged

Sorry and thanks, John B (did you get "sloop" all thru school?) - I stand corrected and informed - though there are more analogs than just bedsides :) 73

I gave those a value of 0, to indicate that those capacitors are not needed. That said, i havent found time to update the circuit, essentially, the new version uses four LPFs instead of two, a 45 mhz

Thanks to all that responded. Great information! 73, Chris w0anm

An analog radio, Dex. An analog one. john AD5YE

What, you don't have an old no-longer-functioning AM/FM bedside clock/radio in the junk pile? Shame! :) 73 ... Dex ZL2DEX the dumpster-diver who has 2 ATM.

This page has a few suggestions for alternatives:?http://www.pa3hcm.nl/?p=1337 ( http://www.pa3hcm.nl/?p=1337 )

Yes -- they used to have them. They are listed under Audio/Signal Transformers. There is presently no stock, and I doubt they will have any more. And yes, Mike, no one is making analog FM radios any
