Been there...

TS-480 does not have proper squelch for remote base operation. No radio 
marketed to the amateur market does. Kenwood kind of came close at one 
time. The Motorola Micom-H would as it was a micom-2 with different 
controls. This has been my "thing" for a while. I had an HF remote way 
back and the lack of proper squelch was hard on the UHF PA tube, 
sometimes keyed up for three hours straight.

But no plug and play way to control the non amateur rigs out there.

So my next one, in the works, will have proper squelch. And it isn't an 
original idea. As far back as 73 magazine in 72 or 73 there was an 
article to build what essentially is the Motorola Micom squelch from the 
earlier days when it was all discreet transistor circuitry, but the 
article used IC's. And it works. I made a PC board for it and found that 
someone else had done so a few years earlier but they were now 
unobtanium. I have a new board that refines it quite a bit more (fewer 
parts, same function). I have not yet had this board made, have to wait 
till Chinese new year is over to get them made. I made this particular 
one to fit in the space within a FT-857D where the optional filters 
would go.

I also just moved and do not yet have my workshop set up.

If you want I'll keep you posted or I'll post here when it is done. HF 
radio needs this and why a company like ICOM can put it in their marine 
versions and not amateur makes no sense, same for Yaesu.

Also, if you can come up with a junker Micom (pre-synthesized) with plug 
in PC cards, one will be a squelch card that can be adapted very easily.

The BF-888 is pretty nice for the purpose but they also sell a BF-U3 
which I have a couple of. Seems like a different board but I have 
already scoped the BF-8U for interface, with the thought of its use as a 
"micronode". But for a repeater it's going to fall short in performance.

Content-Type: TEXT/PLAIN; charset=US-ASCII Hi Danny, Good to hear from 
you! We've talked over on the 145.41 repeater via echolink in 
Wilmington, NC. Yes, the AllStar software will allow you to use a single 
computer, either a full PC, a Raspberry Pi 2 (preferred) or Beaglebone 
Black to accomplish AllStar connectivity and echolink, etc. As for an HF 
remote base, I don't believe the TS-480HX implements an SSB syllabic 
squelch signal??? For an SSB HF radio, you need some method of 
generating a COS/COR (carrier operated switch) signaling if you wish to 
use the HF rig with echolink (this is due to the echolink half-duplex 
design)....With AllStar, which is full-duplex, the SSB COS/COR is 
optional, but, still -very- desirable. The TM-D710 radio will work fine 
as a simplex node on AllStar. Or, for short range use, a pair of Baofeng 
BF-888 UHF radios can be used to make a full-blown repeater---all 
hardware purchased new (including the RPi2, power supplies, etc.) for 
under $100! (See the bottom of this page for my first prototype: 
http://crompton.com/hamradio/baofeng888/ )...Note that I've run these 
888 transmitters at continuous duty cycle for HOURS at the time with no 
issues--incredible for a radio in the $15 range! See the 
http://hamvoip.org website for more details. 73, David KB4FXC On Mon, 8
