On transmit, all too many hams have signals that are just plain poor quality. Unfortunately, not all receivers/transceivers provide a means for controlling how a signal sounds - to say nothing of the noisy audio stages and tinny sounding speakers that abound inside these devices. Sometimes referred to as "armchair copy," the high quality received signal will sound full, neither too bass nor too treble. Of course, I am talking about rag chew and net operations, not hot DX - where the rules of audio are completely different. After all, a high quality received signal is a pleasure to listen to. Most hams strive for the perfect signal - both on receive and on transmit. These articles will be reprinted to add to the quality of eHam's content and in a show of appreciation to the authors of these articles." This article was originally published on: QRP 5W Heil headset compared to IC-7300 handmike." Editor's Note: Due to the popularity of some of eHam's older articles, many of which you may not have read, the team has decided to rerun some of the best articles that we have received since eHam's inception. Heil headset compared to IC-7300 handmike. Wide, Mid, Narrow audio bandwidth transmission comparisation. Setup on receiver side: WebSDR TU Twente (Enschede JO32kf), 80m, filter 2,4Khz, notchfilter on. The only difference that amazed me was between the original mike and the heil headset when working QRP 5W recorded at a webSDR online. But actually.I don't hear much difference, that could be due to the 2,4KHz filter from the webSDR but I think most operators listen 2,4KHz or smaller. Since the IC-7300 has a WIDE, MID and NAR setting you should be able to hear a difference especially in a noisy environment and with a weak signal. However, you need to have the settings on the IC-7300 right to have it sound really good. I'm not shure if it is a little overkill, but the quality seems to be good. Completely different from my previous cheap chinese headset I used for over 10 years on my IC-706 (actually it features already in a video from 2007!). I also bought a new headset, a Heil Proset Elite IC. One of the first things I wanted to do is the setup for SSB. And to use the radio to the max you need to have it all right. A disadvantage of this radio is that there are too many options. I didn't have much time and all the time I had for radio has gone into learning about my IC-7300 setup. Sorry I didn't write much in my blog over the last few weeks.
