Receive audio quality

 

I just got a X5105 and have heard comments about audio being tedious listening with headphones. I have not tried a good external speaker but have tried two pair of headphones and am very disappointed in audio for ssb. Cw seems ok. Playing with AGC helps some but still seems terrible. Even the cheap ubitx blows it away for audio that is more understandable. I guess it is what it is. This one needs a fw upgrade when I get a cable. Maybe that will help some. Intelligibility is rough in noisy conditions. Anyone have similar issues?

Hi John,

?

Bought mine new from MFJ with Ver 3.0 FW. I am a strictly CW operator, with a few listens on SSB. For CW, I have found that by optimizing the filter/audio features, I get awesome reception with noisy or QRM condx, as follows:

?

  • DSP-FLT, leave ON and carefully set the H_CUT and L_CUT freqs for your ear. This makes a huge difference. I use L_CUT 300 and H_CUT 1000
  • NR, leave ON as it removes most local QRN/ignition type noise.
  • NOTCH, leave ON and carefully set the CNT and BW settings for your ear. I use CNT 700 and BW 100.
  • EQ, leave ON and carefully adjust the BASS, MEDI, and TREB. I use BASS 0, MEDI +6, TREB +3.
  • I also use a homebrew speaker/amp with tuned-stereo ports (PVC pipe extensions over speakers), as pictured. Ports are optimized for audio BW 300 ¨C 2000Hz. With the volume just cracked open I can fill the room with an 600 ¨C 900Hz CW tone and NO QRM/QRN. Not sure how well this works in SSB.

?

My technique is to leave everything off and monitor until I engage a QSO and than enable everything, including using RIT, until I get a comfortable listen. I hope this helps.

?

Best 73, Lou N2JPR

Thanks for the tips. This one is running 1.04. I will do the upgrade when I get a chance. I really like my old Ten Tec R4030 (Youkits rebranded) but I had heard how great the tuner worked. I mostly stick to 40 cw portable when camping. Not really into Pota/sota yet. This one came along at a good price so here we are. The guy had lost the keyer cable and USB cable so that is next. Hopefully the upgrade will give more options?

I also found the audio amplifier built into the 5105 is easily overdriven and causes distortion which makes the audio sound a lot worse than what it¡¯s actually receiving.? What I¡¯ve done to fix this is get a real cheap battery operated Bluetooth speaker which has an audio input Jack.? Walmart had one for about $10.? The key is to keep the volume on the 5105 below 50% and use the amp on the Bluetooth speaker to drive volume.? If you do this it will sound like a brand new radio.

Great post, Lou.? Very helpful.? I'm going to try your values and see how well they work for me.? I tend to use a bit tighter H- and L-cut values.? For NR, did you mean NB?? That's the one that helps fix ignition, pulse type noises.? I use the NR and push it pretty high for CW.? It works for me to reduce the "SHHHHHH" noise these radios have in the audio.
 

I turned off the agc and set rf gain to 45. 40 and 75 meters sounded better on a dipole?

I use a similar speaker made by Sony (XB-12).? While discontinued , I was recently able to find them new on ebay.? It¡¯s either wired or Bluetooth.? I use it with my X5105, my X6100, and even my IC-705.? The 705 has fairly decent audio already but the external speaker brings each radio¡¯s audio to another level.? I just wish Xiegu would get around to making the Bluetooth audio work in the X6100.? Until then I¡¯ll be wired with the Xiegu radios and wireless with my Icom.? This is money well spent it¡¯s simply a whole ¡®nuther audio experience with an external speaker.? Thomas K4SWL swears by the similar Anker speaker.? Get a quality external speaker, you won¡¯t regret it.
