I know the IC 7xxx series have this, are there any others that can present audio and COM port interfaces to a PC once connected?

There's a USB socket on the back of the new Kenwood TS-990 but its function is unknown.

Kenwood TS590 does this - audio and CAT over a single USB port - it was one of my reasons for buying it as I like doing digital modes. The radio is seen as both Silicon Technologies USB-Serial converter and a generic USB soundcard by Windows, Linux and Mac OS X.

At its price point it is the best value/performance per $ radio on the market offering this.

The Kenwood TS990 also works the same.

There are a number of approaches, with a USB interface port.

Some are custom, others are multiple ICs assembled in one appliance:
USB HUB/bridge chips with a USB/serial bridge chip and a CODEC/Sound card chip attached to the HUB chip.

Kenwood TS590 does this...

At its price point it is the best value/performance per $ radio on the market offering this.

The IC-7410 ($1600) does this and the street price today is only $90 more than the Kenwood ($1510)... and we all know that Icom makes much better radios than Kenwood so it is well worth the additional cost!

Some Yaesu rigs have this capability, but not starting until the FTDX-1200 ($1800). The street price is already $200 more than the IC-7410, but you also will need to buy the SCU-17 interface box and that cost an additional $190! The FTDX-3000 has USB built in, but that rig is $2430. Oddly enough, their new "flagship" FTDX-5000MP does not even offer this feature at all.

Having this all-in-one USB port is also the same reason I bought the IC-7410. However there are two things you can not do with the USB port:
1) FSK RTTY. Of course the rig will do this mode (and does a fabulous job at it I might add!), but you have to use the ACC port on the back and of course this requires a separate interface.
2) CW. Of course there is a straight key jack on the back and the keyer jack on the front, but if you want to use computer generated CW, you will also need yet another interface.

Now when I say "interface", what I really mean is that you will need a simple level converter. If you have a "real" serial port on your computer, this can be as simple as an NPN transistor and a 1K resistor for the FSK keying line, PTT line and CW keying line. I use a desktop and I added a dual serial port card ($10 at Newegg) so I wouldn't have to deal with those silly USB-to-serial adapters which can be a real pain at times.

And  there you have it!

I, also have the IC-7410 xcvr...use the Signalink USB for all digital modes...Now trying CW; already have an external keyer, plus my rig has an internal keyer...experimenting, now with both.

My pc only has USB ports, so my new external keyer also accepts the USB connect (lucky me Smiley).

i use software for the receiving part of CW, only.

I got rid of my RigBlaster Plug & Play when I got my 7410. No need for it! While the SignaLink USB is a nice interface, it won't do FSK RTTY (unless it is modified as in the May 2013 edition of QST). If you are doing AFSK with the 7410, you are missing a whole host of great features dedicated to FSK RTTY like a separate set of filters and Twin Peak Filtering.

For CW, I use the straight key jack in the back for computer generated CW and you can also use this with an external keyer. My paddles, however, are plugged into the keyer jack on the front of the rig. The radio does not differentiate between the two so you can use them both at the same time. In a contest for example, 99.9% of the transmitting is computer generated, but I can still use the paddles for a "free form" message during the exchange if necessary.

I would not be so bold. Also 7410 is a recycled older rig and not a all new design like 590.

Now add a 2.7kHz and 500Hz roofing filter that comes as standard with a TS590.....

You are talking entry level DSP with this rig. All DSP is not equal.

|Really, you think that about the 7200?

I beg to Differ, the IF DSP
Is the same as in the 7600, they did away with the fm and tuner, to make the 7200,
Comparable, to your kenwood 590.
If you have never used one or have one, dont make a comparison of a radio you dont have.

Thank You

Huh, they did away with the fm and tuner to make it comparable to the 590. How does that work? It can't be comparable minus the tuner and fm???
