Hammarlund hc 10 manual

It may go on a high shelf for the time being. I much prefer the HQ audio quality paired with a Signal Slicer. And its crystal filter is adequate for casual CW work. In the sx, and others, that affects the audio a fair amount. This certainly isn't my idea, I found it somewhere on line years ago and put it in my and It works well. I know they say to come off the last IF, but I'd be tempted to hook the 10's input right to the output of the 's Mixer, because as you say, you don't need all that extra gain.

The one sideband at a time approach provides better interference rejection since you can reject interference that is either just above or below the center frequency; the both works well for use on a net or roundtable whee some modern equipment is only transmitting either upper or lower sideband on AM. It won't be high fidelity but it isn't a brickwall filter either so recovered audio response does extend somewhat above 3 Khz. I do like the Hallicrafters setup better in their selectable sideband receivers.

They don't provide a both sidebands at once option but in the widest position they do provide a 5 Khz. Otherwise with the steep slope, you can't place the carrier at all down the slope and it tightly restricts the maximum AM audio frequency.

I've got it back on the bench and trying various options. NEW: Mesh novice? Want to know more? Click here to view an introductory Broadband Hamnet slide show.

The goal was to achieve on-the-air performance that would be indistinguishable to a listener from that of any other transceiver heard on the band.

Moreover, the rig would be simple enough to demonstrate that any Radio Amateur could duplicate it from junkbox parts and with a minimum of test equipment. It is far from state-of-the-art, but it reflects what can be done with junkbox parts.
