Hi all,
I am new here and I thought you might like to see a recent post in by blog about how to build a cheap USB interface to radios which lets you connect a radio to the PC and control its push-to-talk button. Including schematics.
This interface is enough to connect a radio to Echolink (I am using it for Svxlink).

You can see it here:

Would love to hear your options about it Smiley
Also, do you think I should publish it anywhere else so it would reach the right audience? I am not really sure where to post something so hams interested in this would find it.

Yes,

You used the a Break-Out Board (BOB) that uses the Silicon Laboratories' CP2102 USB to Serial IC.

Spark Fun Electronics, Boulder, CO offers this and other "BreakOut Boards" for the DIY Builder.

BreakOut Board for FTDI FT232RL USB to UART (Serial)
http://www.sparkfun.com/products/718

FTDI and Silicon Labs are the PREFERRED CHIPSETS for USB,  GOOD OS Drivers (well supported).

BTW -- SparkFun accepts Application Notes and Articles -- some of these have been amateur radio related !

The board you posted costs $22 (without shipping), the one I used costs $4 (with shipping) as in 5 times more.
Could you please clarify, why is your reply relevant to my cheap project?

You could publish it here on eham.net - in our articles section.

I just saw a CP2102 breakout board on ebay for $3 shipped!  I think I'll order one to play with - are the drivers easy available?  Does it show up as a COM port as does the much more expensive FT232RL chip?

Thanks for the thread.

Yes they show up as a COM port, and you can set which port you want it to be. The driver is available here. In Linux it gets detected automatically too.

Silicon Labs, Austin, TX (USA) is one
http://www.silabs.com/products/interface/usbtouart/Pages/default.aspx

of 2 well support and widely available USB to UART (TTL) or Serial (RS-232) chip manufacturers,
the other being FTDI, based in UK.

Prolific USB chipsets (Taiwan) found in many inexpensive "big box" store bins ---
suffer from poorly support for COM/VCP drivers for various Operating Systems (OS).
In fact, the Prolific web site has been unavailable in recent weeks.
