Re: Going wide for FM

I should now apologize for the late response.. I have wired the rack to my Kenwood TR-751A 2m multimode and all the comments I receive are positive with some describing the audio as FM stereo broadcast quality or better. I think it helps that this radio has a good audio section to start off with. So...

Re: TS870 - C131 Cap Mod

I should have also asked... Is there any need for a device such as a W2IHY iBox of passive DI/Ground lift between the audio gear and the rear audio input?

Re: TS870 - C131 Cap Mod

I have seen the information in a dozen different places with almost as many variables of cap value from 1uF to 4.7uF...
So which one is correct and why, how does the value and effect the results?

There were at least three stations in conversation and they were interrupting and speaking over each other, not just doubling.. unfortunately I could not transmit due to excessive background noise i...

Full duplex??

Listening to a couple of eSSB users on 3.360Mhz on Saturday evening I got the distinct impression that there was a full duplex conversation in progress..
Is this an artifact of the technique and operator experience or have I missed something?

Use of ACC2 for original purpose

Does the cap mod prevent the ACC2 connection from being used for data modes?
My assumption is that the change in audio characteristics should have no effect on data modes therefore not requiring any de-mod or switching.

Going wide for FM

While getting better, deeper, wider, sexier sound of SSB is the goal of this side of the hobby I am interested in applying the principles and techniques to all voice modes - even those nasty digital ones. As most of the modern rack equipment is either easy to adjust or has a memory function the pros...

Way back in the mid 90's I was applying the technology and techniques from my job as a radio station engineer and on-air talent to my hobby with great success. ...
