Thanks Henry and Gary, I am familiar with setting up the eq on radios, etc. ?z as this definitely is not an EQ problem as it exists throughout the limited frequency span of the radio. ?It is jus

Thanks Alan! As to the radio, I'm still working my way around the menus and things. The audio I have heard is adequate, but I can't say if I'm not hearing what you do because of my ears, or if my

The TX-500 has EQ on both TX and RX. The speaker mic will never sound great but you should be able to get intelligible audio with some EQ adjustment. Bob Heil has some great presentations on Youtube

Alan, I made a number of phone QSO's this past week and did not notice any unusual audio distortion when using the hand mic/speaker, headphones or external speakers. The problems I hear are due to the

I forgot to thank Dan in the previous post. Thanks Dan. 73, Alan N5AGY

Mark and Michael, Thanks very much for the replies. Michael, your explanation was what I needed. Thanks! I did figure out that the blue covered interface is the FT-232, and black is PL-2303. It’s in

Yes Alan, as Michael explained - it works fine I've used it on the Mac with a the home made digital audio cable for FT8/WSJT

Very clear explanation, Alan.

Hi Alan, So the USB cable that has the blue end, that plugs into the CAT jack on the TX-500, is a USB to Serial cable. To do that it has a small circuit board inside the blue cover. This circuit board

Has anyone successfully used the usb cable (blue connector) that comes with the radio for cat control? ?I don’t see why it wouldn’t work, but I can’t seem to be able to. ?If this doesn’t

Re: [Lab599] Single-ended audio output (MIC/SP)? Let us know how it works out Dave. I called HRO HQ and was told that my TX-500 will ship from the next batch which they expect end of this months or

Thank you, Yvon. I think AC output voltage for single ended use of BTL design will be 50% of BTL connection (instead of Bias+V - Bias-V = 2V, now Bias+V - Bias = V), therefore total AC power of single

Dave, you could connect one of the speaker output through a 470uF capacitor to one end of the speaker and the other end of the speaker to ground. You will have half of the audio power output and maybe

Thank you, Yvon. I have no experience with Omega 900, but I have designed two audio output amplifiers that included option for this kind of output interface (or other option, single ended.) I agree it

Dave, I also have an Omega 900 that has the same problem, The reason is, and I assume it is the same for the TX-500, the audio amplifier is an integrated audio amplifier IC that has a balanced output.

That’s the number that is on the photo I sent ????? ??Sent from my iPhone.......?

Anyone know where I can buy the amplifiers for the TX-500? Thanks! Aaron
