heres an odd one i never heard of, i picked up a browning mark 3 , a/m only transmitter and the receiver is the standard receiver with a/m ssb . i already had another receiver that looked and worked better so i hooked the 2 together, now when i switch the receiver to ssb it also transmits on sideband, anyone ever hear of this>?

I haven't. How do you know it's transmitting on sideband?

I've heard and seen it. I've tried to explaine it on this forum but no one either believes me or they think I had another model. I'm glad that you brought this up. This has been about thirty years ago and at the time I had a base set up in Cape Canaveral, Florida. I had this radio for about a year before I found out that it would work on sideband. Everyone tells me that what I had was a SSB 15 but it wasn't. It was a Golden Eagle Mark II. The receiver had a switch for sideband and the transmitter had nothing with any switch or anything marked for sideband. The transmitter was marked "Golden Eagle Mark II". That's all, no marking about SSB 15. I was talking to one of the locals and mentioned that I didn't understand why the receiver had a sideband switch with a smaller knob marked "fine tuning" but why because the transmitter had nothing marked anywhere about sideband. The fellow that I was talking to said that yes, it will transmit on upper and lower sideband too. Sure enough, I switched the receiver to lower sideband on the channel that we were talking on and we talked on lower sideband for about an hour. I used the small fine tuning control on the receiver as the clarifier. He told me that my radio sounded good on sideband. What I want to know are all mark II's like that? What model are they really? Obviously your AM only Mark III is the same way. I wonder if all AM only Mark III's are the same as yours. I sure would like more information on this. No one on this board can fully understand what I'm talking about. They keep saying that my radio was a SSB 15, which it wasn't. I've seen and operated SSB 15's. Now I wonder if these radios are double sideband rigs or are they true sideband?

You might have been receiving LSB and the person you were talking to was as well, but AM can be received on SSB just fine as long as the carrier zero beats, which happens when the fine tune is set properly. It would have been revealing if the other station had dropped back to AM while you were supposedly on LSB, and most likely he would have heard you just fine on AM. |

i have the a/m transmitter mark 3 and what tombstone is saying is true, i can carry on a conversation on sideband just like he says, i dont quite get it but just did it a couple of weeks ago, a/m transmitter, a/m, sideband receiver.
actually i have it for sale in the for sale section,
nobody believes me either about this working this way on this radio

I see what you mean, Sandbagger. The MarkII transmitter that I was using had no mode switch. Yes, if the other operator that I was talking to had switched his radio back to AM while I was still supposedly on LSB then that would have been a true test but back then I never gave that a thought. What you are saying is the most logical explanation of what was going on, and now that I've thought about it, the small fine tunig control was on the transmitter, making it possible to zero beat the transmitter to the receiver. Since the receiver is tunable instead of crystal control, that's how I was able to clarify him. My question now is why did Browning put a AM/Sideband receiver with an AM only transmitter? The receiver did have a mode switch. I wonder if all of the Mark II's were like that? Thanks for clearing that up. On another note, my Mark III is set up with the Nomad slider/buffer kit and Siltronix 90 slider and that's how I tune it on sideband. I clarify the receiver and then zero beat the VFO on the transmitter. Makes sense.

The almighty $. Since the Browning radio setups were two piece units, it didn't make any monetary sense to eliminate the SSB capabilities of the receiver. This also eliminated the need to carry an AM only receiver.
However, someone looking for only AM transmit could just buy the AM transmitter and save a few bucks on the cost of his Browning setup. Later on if he wanted to upgrade, he only had to purchase the AM/SSB transmitter since he already had the receiver.
