I talked over the air to another Ham who has a Ft-950 and the end result seemed to work fine using My MD-100 Desk mike.Īfter I bought My Heil Proset plus I set it up over the air also but with another ham.

If you do this, and you direct inject the balanced modulator, and you set the 8.83Mhz IF filter to the bypass position, _and_ if you install a jumper wire in the 455Khz CW filter slot and use this as a bypass position for the 455Khz IF, you can get almost 10Khz of AM audio bandwidth.When I first set up this radio, I changed some of the Parametric Equalyzer settings and also the Tx bandwidth. (Normally if you press these buttons with the transmitter engaged, nothing happens.) If you select option 1 from this menu and set it to 'on' you will be able to use the 8.83 and 455 buttons to select the filter settings in transmit as well as receive. By default it shows you a checksum of the firmware for the main computer. In addition to this, there is also a hidden service menu, which you can access by pressing and holding both the SCAN and TX/M.CH keys while powering the rig on. To access the menu, you have to press and hold the LSB/USB button on the front panel while you power the rig on. The whole list is documented in the user's manual. You can also set the M.CH/VFO CH and main tuning knob stepping rates, select which subaudible tone to use for 10meter FM repeater operation and a few other things. The configuration menu can be used to turn this off, which I did because it just bugged me.

It isn't very sophisticated, but it's there.įor example, normally the radio emits a set of morse code beeps through the speaker when you select a mode, to announce what mode you just chose (AM, FM, USB, LSB, CW). It is fun, and it makes the hobby more interesting than it was ten years ago - IMO.Ĭlick to expand.The TS-850 has configuration menu that lets you adjust certain functions. There are plenty of eSSBers that have YouTube videos that prove conclusively that it can in fact be done right. Neither is it necessary to have a SDR-1000 to do it right. Just because some radio operators have made mistakes trying to do eSSB, it does not preclude that it cannot be done correctly.

No skin off of anyone's nose, except that running 20k wide will take up too much bandwidth under the rules is all. The problem is found in the 'other radio' because it cannot hear all of what the other radio is putting out. The PA section cannot tell the difference, IIRC. There is no such distortion because it is running 20k wide to another radio. Having run a FlexRadio SDR-1000 ('my fave'), I can tell you that the filtering in it is all done digitally. The other option would be to change the values of those caps, and that can also be done. The reason to inject directly into the balanced modulator is to avoid all of that. This helps the filter have a better shut-off slope when it kicks in.

That would violate amateur rules of proper freq use.īesides the presence of filters in a radio, the engineers have also added caps to the mic audio circuit that cause the mic freq to begin the process of shutting off before it reaches the filter for both the low and high freqs. That is the tip off, not because that would be impossible to do, but rather because that is not the goal. The proof of this is their claim that the amateur is 'attempting to have a commercial broadcast station'. They don't understand it, it is new and therefore threatening, and are unwilling to understand its place as valid experimentation. The complaints made by some Hams is a 'sour grapes' argument concerning eSSB.

Compression is real art form, and is often the one processor that is least understood and often done incorrectly. If equalization is the issue then a mic better suited is chosen, rather than EQing both pre and post recording.
#Essb audio samples how to
Guys go to school how to do that, and end up taking in years of experience before they can even be considered to be a real 'pro'. Ask someone who worked in a recording studio. Running audio gear for best results isn't as simple as one might think. A radio can TX as wide as the filtering will allow, and can even be byassed altogether. The only 'splatter' that is possible - that I am aware of - would be having the ALC too wide open on SSB mode.
