[chirp_users] FT-60 and CP2102
Turns out it looks like most of the CP2102 USB adapters are 3.3V output. Specifications for TTL logic is 5V. I have ordered a CP2102 that has both so we'll try that and see what happens.
In the dim times (when we used a kerosene lamp to illuminate our computer screens) a common practice was to use a Max232 to convert RS232 levels to TTL for programming radios when you did not want to purchase a $40 cable from RT systems. It was often hit and miss if the radio would work because the levels were sometimes not quite right.....
Should have the different CP2102 this week and report back.
Thanks for the response Jim. I wish it as easy as finding a short. I have three of the converted 6-in-1 cables and the behavior is the same. I will keep playing with it. I did not order the cheapest available CP2102 available from China and notice there are several different styles. Perhaps this one is somehow different in levels or buffering from the others. I have read online others have had success programming the FT-60 with the CP2102 so something is different. One thing of note is this is one of the CP2102s that John said has the TXD and RXD switched.

The cable works perfectly with the UV-5R radios but no longer works with
the
Yaesu FT-60. It is the same with my MacBook Pro or if I use FT-60 commander. I thought before I start spending several hours chasing this down I would ask if anyone else has run into this.
Thanks,
The MAX232 method is likely gonna be picky as heck unless there's a constant power source available. You can use the DTR line on the serial port but on some systems this isn't driven with enough current.
That being said, this is what I've used.
I just tossed a 2N2222 and 2N3904 in there as the PNP and NPN transistors. Never fails.

See this for an externally powered version which may come in handy should the host serial interface decide to be a REAL pill about how much current it's gonna source. :P http://mw0gkx.co.uk/radprog/icomhw/opc478.htm

So are you trying to use the same cable with both 3.3v (Baofeng) and 5v radios (Yaesu)? I think it would be cheaper to have 2 cables in that case.
