Great video but i take my audio thru the Acc balanced modulator at the rear of radio avoiding the front end mic input which can be noisy and limits the lows on radio . Find it much cleaner on my icom and kenwood .
Justin, when you do connect XLR mic to kenwood, how does the wiring go? I noticed that kenwood had mic+ mic- and GND on both front mic and ACC conecctors. I took my senheisser mic and connected it to kenwood (TS590S) straight like that. Mic+, mic- and GND of XLR is connected to GND of TRX. I found no issues with this. Would be this correct? @TheHamRadioJunkie what are your thoughts on this ?
thanks, keith! so, on my FT-DX10 I am running a xlr condenser mic into a neve 1073 preamp / eq combo. i tried connecting the output from the neve to my radio, however at even the lowest level setting on the neve, i am getting what appears to be a blown out FM signal on the radio's screen scope while in LSB on 40m. will an off-the-shelf xlr audio transformer from amazon fix my issue?
nvm, i figured it out. i built this bal to unbal cable with an inline 600:600 transformer plus a 1k pot with the center wiper and right pins going to one input wire on the xlr out, the the cable is effective. good signal to the radio now. so, my chain is: mic xlr input > neve > xlr out > the cable with trans and pot > radio.
Thank you for the info. I have been fighting with my mixer for quite awhile now. I have been told all kinds of things. It looks like my problem is using the wrong output from the mixer to the radio and trying to use balanced cables. Thank you!
Nice one, my mixer was put to a boot sale unknown to me. When I asked where it was I was told "I put it to the sale as you were not using it and I am not going to store it!" "How much did you get for it?" "£2.50p" :-(( Someone got a real bargain! I will gladly buy it back for £5 :-)) Oh well, standard mic it will be then.
@@TheHamRadioJunkie Yeah, I know, she had no idea of the value. When I tell her the value of anything she always say I exaggerate. :-( She has still not learned from it!
Excellent video. I am confused about the part where you discuss using the mixer. If the mixer's "main out" is the 1/4" unbalanced jack, why are you showing the schematic (timecode: 5:40) for a balanced output while discussing mixers? Main out only has two conductors. Please clarify. I may have missed something. On a side note, I did buy a 600:600 transformer and a 1K pot. Ready to put it all together to connect my audio mixer to the Yaesu FDTX-10 input.
Frank, correct the diagram does show a balanced output. For an unbalanced output the green wire, as show in the diagram is omitted. The resistor will go between the output and the input.
@@TheHamRadioJunkie thank you. I guess there is no advantage to adding a 1:1 audio transformer to the main output of the mixer. Correct? Just add the pot/resister in series to the output’s tip lead and I’m golden.
@@FranklyRustic the transformer can help in case of a "ground loop" or the power supply for the mixer is not isolated well enough from the power supply for the radio and they see each other but the ground potential is not the same. A current can flow from mixer to radio (or vice versa) on the *signal wire* in that case. A transformer isolates this current and also eliminates common mode noise ("hum"). A capacitor can eliminate DC current flow on the signal wire but does not eliminate hum. This is a bit extreme; normally if your radio and your mixer are powered from the same mains phase, you won't have a problem especially if you have good bonding of the ground connections. You can buy inline transformers of the XLR variety. Google "xlr audio isolating transformers"
Hello Friend. I've the same questions that Frankd9134. My Xenyx1002FX there an unbalanced output. In this case, can I use a Y P10 cable to input in my TRX?
2:55 The text is misleading. Noise arrives at the balanced amplifier input IN PHASE ("common mode"), not out of phase. The desired microphone signal arrives out of phase and is amplified. The amplifier is a differential amplifier and ignores, mostly, common mode noise that arrives on both wires at the same time.

Thank You mate. I have to connect my Henyx802 mixer to my 2 hf radio. Your infos are very useful. Cheers from IZ6AVE Italy.
Thanks Keith you answered all of my questions

Cheers Callum. I'm trying to pick subjects that people may find interesting.

Isnt the 1uf blocking cap, going to limit the audio bandwidth ?

@@FranklyRustic can you tell me what mixer and how you wired your ftdx10 radio. Having issues with getting mine to work

Can I ask if I can use a mixer just to improve the rx part quantity, I mean completely remove the noise at background?
Marco, sure you can use a mixer to equalize the receive audio. It may not remove the noise but may improve what you hear through an external speaker.
@@TheHamRadioJunkie cool thanks
Nice info, seems too much trouble for me ☺️
👍👏👏
I know a fist mic is so much less trouble.
I realize it is quite randomly asking but do anybody know a good site to stream newly released tv shows online ?
@Juelz Zander try FlixZone. Just search on google for it =)
@Karson Joshua definitely, have been using Instaflixxer for since april myself :D
