Nice demo; It was a great idea using a second radio set to receive the transmitted signal to show how IMD (Inter-Modulation Distortion) W-I-D-E-N-S the transmitted spectrum thereby clobbering the adjacent signals!

Two points, but first of all, great video. TKS! First, the reason ALC is kicking in before "full power" is indicated is because of the difference between Peak and Average power. You are putting out full power just before ALC kicks in, even tho you don't see it on the meter. Second, I use an audio pad between the computer and the rig which allows me to operate audio more toward the linear region of the sound card (and it gives me a wider range to fine tune the audio level). 73!

Hi again Andy. Just came here from your fine DigiPan introductory video. This video here is also excellent & have learned much more. Have even checked the IMD figure from my TS590s using a nearby txcvr, so I can avoid excessive bandwidth - probably a pitfall for many beginners like me! Again 73, and thanks a lot. Norman, G4LQF.

@insideofitall You can still have distortion even with low power. The distortion comes from over driving the system. Set the audio level, raise it and watch the power out. When you see power out not increasing, back of the audio level a bit. Try a qso and ask if you signal is clean.

@lioii I would think no. FSK is for RTTY, and it is not dependent on audio levels from the pc. I think you need to be in the mode that the sound card is feeding the radio and adjust the audio level so that you are not over driving the radio.

I usually set mine up by the forward output and make that needle bounce as much as possible it will hit 100watts sometimes but, not all the time! when no text is going thru it should be at least 25% weaker than pep. bpsk31 is not 100% duty but, pretty close. in mixw there is a neat feature for audio levels called Amplitude level for this mode. set to 1.000, 1.000 is full output audio set to around maybe .3 to start and see if you can hit 100 watts. continued

that way it would be hard to mess up the audio settings in the mixer program just keep it full blast all the time. I also recommend getting a 2nd pci sound card so windows and webpages sounds don't get transmitted out. That way you can jam to music while in QSO with your friend on psk .. Hope that helps as well , tnx for the vid 73 to all

Thanks for the video! I just got the FT-817ND and am setting it up so this is a big help. One quick question. If the IMD is okay, and you're not at full-power on the rig (maybe 2 or 3 watts or something like that), is it fine to have a couple of bars on the ALC? Since these rigs are low power as it is, I want to get as much out as possible without distorting or worrying about my finals.
@K7AGE12 жыл бұрын
Sounds like you are using VOX to key the transmitter. The audio may be just a bit different on 40. Try tweaking the level up a bit from the computer, and reduce the audio gain on the transmitter. Or, if there is a VOX gain setting, tweak that a bit.

Hi Randy, I just got a K3 and a MicroKeyer II. The MK2 setup instructions have you adjust the ALC so about 5 bars are showing (7 bars is max). Does this sound right to you for PSK? Thanks for the videos! Jeff, W6UX

yea that is one of the big myths out there about strong bpsk signals. no matter what power setting you are at you can have a dirty signal. Some things I seen out there that can cause some problems is ground loops, a sound card with high THD% , EMI from other equipment or AC lines, RFI from the actual transmitter getting into the audio lines or chassis. one thing I found on some rigs out there is that the ALC meter will read wrong somtimes.continued

+mykenwood830 TRY "FLDIGI". I have to keep reloading digipan with Windows 10 too. The audio keeps going out on "Digipan", and it won't come back until I reload it. I can unplug the speaker jack, hit CQ TX, hear a pop, and then nothing comes out. FLDigi has probably 200 different types of digital modes from MFSK-31, QPSK31, Hellschreiber, CW, Olivia, Domino, Throb, THOR, RTTY, Weatherfax, Contestia, MFSK, MT-XX, etc. It has some super fast freq & phase shift modes, and some really slow narrow band modes that will transmit through mud. When I tried the "help" button for Digipan it went nowhere, telling me it has been orphaned, forgotten and FLDigi is the new "in thing" now.
