I am trying to get an ICOM IC-7200 to work with fldigi.  I can talk to the radio no problem (change frequencies via the program, etc.).  The issue I am having is the program "hearing" the radio.  In the configuration section under Audio then Port Audio you are supposed to pick capture and playback devices.  I've watched a few videos and searched the interwebs, they all say that you should select a "USB" device.  I don't have any USB devices in the list.  I've also tried every other device that is on the list, nothing works.  Suggestions?

run these commands, and post what you get:

"lsusb"
"aplay -l"
"arecord -l"
and "dmesg | tail" but remove any identifying information before you post it.

Oh.

Well, other people here will have to help. I've never used it on windows. I can figure it out when I get home though, I just got a new windows laptop.

Unfortunately, I am a step behind even those guys, I can't receive.  This is more of a windows issue (I think) as the USB devices that should be there for capture and playback aren't there.  When I turn on the radio, Windows does recognize it.

Mugzilla hit the nail on the head. This is the definitive video on how to get the 7200 running with Fldigi. This is the third time it's been posted in the arfham forum in a month (twice by me ). Maybe it should be a sticky?

In the meantime, here it is embedded for you. Grab your radio, your computer, your beer and follow along step by step. You can't lose!

This is the exact video I watched.  I get to the point where you select the audio capture and playback and I don't have a "USB" choice, only the standard choices that are built into the PC.

If all the drivers are installed the radio should look like a serial port and a sound card.  Since you can control the radio the serial drivers are obviously installed.  Look in Device Manager to see if a sound card appears then disappears as you connect and disconnect the USB cable to the radio.

Now I am really lost.  I tried to see if any signals have been received.  It says my station was heard from 14 hours ago, but on it shows me in bands and modes I wasn't transmitting on.  Worse, I called CQ a number of times on 20m this morning, it still says I haven't been heard from in 14 hours..even after an hour has passed.  The radio does switch over to transmit as I can see it go from RX to TX, but I don't know that I am transmitting anything.  I don't hear the radio transmitting when the audio is set to the USB device.

What mode were you calling in and what time was it?
As for the reports on bands where you weren't that's just a glitch in pskreporter. If the receiving station changes bands then it will report on the current band. I've been reported plenty of times on bands I have never transmitted on.
To see if you are actually transmitting anything switch to the PO meter on your radio (Top left "METER" button that scrolls through SWR/ALC/PO) adjust the Power with the volume slider on your computer.

Have you tried the free version of Ham Radio Deluxe? Both programs get good reviews here but I prefer HRD myself. The biggest complains are lack lf support for alternate lifestyles...er...operating systems and the fact that it is a bit bloated (true).

No, I haven't tried the free version of HRD, and I am truly not opposed to paying for the full version if it works better than fldigi.  The meter says I am transmitting, but is it actually transmitting anything useful.  I was calling about 8pm central last night and for the last hour and a half on 20m PSK31.  The call sign is KD9AFO.

Another quick question for you. How many watts does it say you are putting out? If you are getting garbled text with half of a call sign then it sounds like everything is working. Perhaps the antenna or propagation just aren't cooperating with you? Are you in front of the radio right now?

Here is HRD Free: http://www.iw5edi.com/software/ham-radio-deluxe-5-download-links
Be warned it may take a bit to set this one up too. But once you get either of them going then it should serve you well. There is a post by in in the archives from February of this year asking about setting up the digital modes and someone gave me a step-by-step. I'll try to find it.

Any decoded text means the radio to pc setup is correct.

If you set the meter to PO and press the tune button in fldigi do you get any power out?

Not sure how it works in mac, but there should be a separate audio control for the USB soundcard someplace.

If you are having trouble decoding make sure that ALL receiver DSP functions are OFF. This includes NR, NB, EQ, RIT, IF Shift, etc. Also make sure your received audio levels are correct into Fldigi.

On transmit, again all DSP functions should be OFF. This includes EQ, compression, etc.

Has anyone asked how he is setting his TX power? I am not a ic7200 expert so I will leave the settings to 87% of ARFCOM that is. ALC might be a reason no one is seeing him.

As for the RX. There is a squelch slider in the lower right. Make sure it is adjusted.

The best way to set transmit is best understood if you know audio, "headroom", etc.

Set power on the radio to 100 w, that is, full power.

Use an external power meter.  Set the radio's meter to show ALC.

Starting at zero audio drive from the computer, gradually increase the audio output slider in Windows, or in your
digital program watching power and ALC. If you see ANY ALC, back off until it just disappears.  Or just as good,
watch actual power output via a known quality power meter.  When you reach 20-25 watts, stop... or back off to
10-15 watts if you want.  

This is much better than just letting the audio drive be high, and setting the power in the radio to 10-20 watts.

If you were to overdrive the audio, regardless of what you set power to on the radio, you will produce a wide, distorted
signal that will spill over onto your fellow hams thereby ticking them off big time.

Power?  You don't need more than 20-25 watts to talk around the world. So, what if you do 50 or 75 watts?  You
will "blank out" the entire PSK portion of the band, and nobody else will see anything on the waterfall except your
way overpowered signal.  Doing this is "lid" behavior.  You will not make friends and other digital operators will no
longer communicate with you.  If they can decode your overmodulated signal and figure out who you are and
where you live, they'll come after you in the night with torches and pitchforks.  You will be a hunted man, a
pariah among hams.  So, just don't do it.

You can talk around the world all day long on 20 watts.  Be considerate of others.

OK, I think I finally got things dialed in, although I haven't had anyone respond.  I am running a G5RV Lite (all the space I have at the moment), I ended up getting it up to 33ft to the dismay of the neighbors.  I sorted out all of the issues on my end (thanks to aa777888-2 for suggesting to turn all receiver functions to off).  The squelch setting on the lower right cleared up the spurious garble that was showing up as well.  Anyways, I sent out a CQ a few minutes ago and it is being picked up all over.    I'm used to the computer world where things either work or they don't.  The interface between the radio and the PC (even though it has a USB port) is analog and touchy.  Thanks again guys.

I cannot get fldigi to output any power tonight.

It is showing the USB codec for sound card.
It PTTs the righ when I hit tune.
But no PO.

You may have the TX level attenuator out of adjustment. Try adjusting this to see if your TX audio output increases.

Transmit level attenuator

It is often difficult to adjust the audio drive for the point where ALC is just barely active.  Mixer controls are OK, but not usually designed for very small changes.  They are after all designed for adjusting listening levels.  fldigi provides the ability to control the audio drive in increments of 0.1 dB over a 30 dB range.  This control is located in the bottom right corner of the main dialog.

I doubt it, but I'll check it.

Feels more like an OS issue, but everything looks right.

I was mucking around with my sdr dongle and connected the 7200 to sdr# in the XP virtualbox.

I am betting something regarding that broke it.

Update...working, but still have an odd issue.

Turns out everything works fine...under 2700Hz on the waterfall.  I was trying to tune up at about 3000 or so.

I poked around in fldigi, but all I could find was the upper limit on the waterfall, and it is set to 3500.

I will read through the 7200 manual, but I am pretty sure this wasn't the case before.

BigDaddy: this is a limitation of the 7200. It's transmit bandwidth is NOT adjustable. It has nothing to do with the settings of the IF passband bandwidth or the settings in WSJT-X or any other digital mode.

For you guys with "fixed" or limited filters the trick I use is to run all my digital at 1500 Hz. on the waterfall and hope the 2nd harmonic of that at 3kHz. is cut off by the rigs output filters. For digital you really want them to roll off before 3kHz. With wider output rigs you might move higher on the water fall but still keep the 2nd harmonic of the audio beyond the pass band so it's cutoff before it gets out. hth 73, Rob
