    Just an opinion on computer interfacing. Serial ports came about in the late 1980s. Shortly after RS-232 was implemented for a somewhat serial communication standardization USB and FireWire came about. USB and FireWire sport more power and and way higher data transfer rates than serial ports do. My question is why have ham radios been stuck with serial ports for the past 10-15 years?

    Part two to my inquiry deals with something similar in interfacing. Bluetooth has been around since the late 1990s and has been quickly adopted in the mobile industry. Until recently (in the past year,) radios whether software defined or not, have been lacking this capability and crippling them in my opinion. Perhaps this is a matter of interference, but cellphones figured it out early on while ham radio got left in the dust.

    So why is this radio community? I know I'm not the only one with this on my mind and with upcoming technologies such as D-Star, WIRES, and Echolink...why did this get left in the dust? How would you like to have memory channels accessible from a iOS/Android device? What about SSTV with a Bluetooth camera? WiFi access?

    Back to my original statement, traditionally radio amateurs are early adopters of technology. With this we embrace and challenge the status quo of what can and can't be done with what we have. We also practice and get familiar with many means of communication because "when all else fails...amateur radio." Thoughts appreciated.

    I think the answer to both your quandaries is that the "big three" Japanese radio manufacturers aren't devoting their R&D into the amateur product lines like they were 20-30 years ago. From their standpoint, they are more interested in their other divisions (LMR, marine, aviation, etc) and put their brains and brawn there.

    Kenwood, for example, was a pioneer in the 1980's with technology way ahead of their time, like DCL, which was a form of trunking, albeit primitive by today's standards, but used FSK signaling to ID a radio and get other radios in your "group" to switch automatically to a clear channel. Digital selective calling was also built in. This was before LMR radios had this capability, and trunking was fairly new.

    Icom had the famous IC-900/901 rigs which used fiber optic cabling, digital control- and this was in the 1980's, well before any USB or even Ethernet became common!

    Yaesu had the first dual band HT in 1986, long before Motorola, Harris and EF Johnson thought about multi-band portable radios.

    Back in those days, ham gear manufacturer's product lines spanned several pages, with two dozen models.

    Fast forward to 2013, most commerically produced ham gear is based on designs over a decade old. The Yaesu FT-8800/8900 first came out over a decade ago. Same with the FT-60, VX-6, VX-7. These are also their best selling radios. The Kenwood TH-F6A came out in 2001. It's still being sold today. None of those radios even feature flash memory for firmware updates, which has been the standard on LMR radios since the early 1990's, let alone USB or Bluetooth.

    The average ham catalog is thinner and slimmer, with few new products being introduced every year. Their priority seems to be LMR/digital LMR a la P25, Nexedge/iDAS, and DMR/MotoTRBO. Ham radio isn't as profitable from a business standpoint, not just because there are only a small number of customers, but the average sale is much less. A single band LMR HT (digital) retails for $450-600 a piece, and are ordered in dozens at a time- and are being replaced every 3-5 years. The average ham HT (analog) sells for under $200 and is sold one at a time and gets replaced every 10 years.

    you tell me why they aren't spending big money building new radios. Especially software defined ones. Software and firmware engineers don't come cheap. Not to mention the support costs. I'd say look to the Chinese who have no problem ripping off other people's intellectual property to come out with cheap radios with these features. They already have digital LMR radios for under $200 showing up on Alibaba. People are snapping up the $40 Baofeng radios by the dozens.

    In general hams are not early adopters as you see. Military and commercial are driving technology now and have been for years. More and more, hams are becoming "users" of technology instead of creating it.

    The manufacturers of amateur equipment took the time and resources to see what amateurs like and don't like. What they like is stuff that works. What they don't like is spending money on something that's just the latest incarnation of the same stuff but works just a bit better. Amateurs get something that works they usually leave well enough alone. So, way too many amateurs are still running desktops loaded with Windows 98 and the RS-232 serial port, the parallel printer port and a trackball. That's why almost all amateur programs offered are still compatible with Windows 95 and up. We upgrade our computers when they tragically fail. That takes a load of time.
    Me, I had a Windows XP machine with the mixture of USB and RS-232. XP is a very good operating system compared to some of the other stuff Microsoft plopped out there. The XP machine died and so I upgraded to a Windows 7. Now I can't run any of the old but very usable DOS programs that XP had no problems with. Yes, I have DOSBOX and that works but when downloading a DOS program that stupid Windows 7 thinks it's an application and until I manage to cover it from that the DOSBOX won't run it. Now they have Windows 8. Some have made the plunge with varied results.
    Okay, so my newest rig has a USB port and an audio codec. It still has a RS-232 port, go figure. If they quit supporting programs all the way back to DOS then why bother supporting RS-232 any longer? The computer doesn't have a RS-232 port so you have to use a converter. Don't run USB and RS-232 together and I don't run that over to the rig either. I do use USB on my rig but it's 20 feet away from the computer. Ever try to run a cable for USB 20 feet? Can't be done with a normal USB cable. You have to buy one that has drivers in it to go that distance. With RS-232 it was just a matter of making the cable and terminating it properly. It could cover much greater distances then USB. USB is much faster. Chicken/egg thing.
    Have fun

    I upgrade computers every few years none have had RS-232 for many years now, what is behind are radios not having USB ports same for accessories not enough USB yet. Win7/64 was huge leap forward in OS's and for software programs the amount of new and better software that was written was amazing and ham programs leaped forward from the old 32 and DOS based mode's. The problem was lack of support for those old mostly "Free" programs that one one to rewrite because of so few features by the standards of that date even.

    You ask why are some still running the old OS's that's easy they don't want to buy a new computer or software one or the other. Because Win7 is the most stable OS we have ever had since it's inception and some refuse to try anything new to them or want to learn new software/OS, but support for Win 64 is about to run out very shortly then no more for it.

    I for one am glad that DOS based programs bit the dust I switched to windows with version 3.1 in 1992 and never looked back. Can you imagine running some of our newest digital modes with DOS.

    I am thinking you hit the nail square on the head with that perception there OTD. Most Amateurs OPs of today are analog men/woman, living in today's digital World. :)

    I think putting a serial port in a radio rather than USB does give the user maximum flexbility to interface to whatever they want.

    The K3 has a serial / RS232 port but of course nearly everyone uses a USB to serial convertor to connect it to a computer. I think if they put a USB port on the radio, all they'd do is put one of those FTDI chips inside the radio. The processor in the radio would still be using serial. So ... I guess the way they do it makes it more "decoupled" so you can use it however you like.

    Admittedly, there probably comes a point were almost nobody really uses serial directly so ... they might as well put the converter chip in the radio. It would probably cost very little in the total cost of the radio and it would save everyone having to spend $30 for a convertor cable. I think the TS590 has a USB port.

    I have seen Bluetooth technology on CB radios lately.

    Most "new" HF rigs (finally) use USB. Flex Radio has used Firewire for many years.

    No reason to not start supporting the Thunderbolt interface. Even Mac laptops do, and new generation Intel-type motherboards do. It's way higher bandwidth than USB or FW800, and could allow PCIe bus expansion into accessories like transceivers. Think how slick it would be to plug in one skinny cable and support 2-3 extra PCIe slots right inside your rig for peripherals.

    It should be coming, but I won't bet on when.

    I wonder why Icom did not put a RS232 or USB on there Pro series radios. When they went to the Pro II the RS232 would have been nice, the Pro III would have been an opportunity to go with USB
