Locked Re: Regenerative receivers and loop antennas
I am convinced, that the greatest problem is the stability, which you can not achieve with regen. When you receive SSB or CW, even some better commercial receivers (such as SONY ICF 7600) are

Locked Re: Regenerative receivers and loop antennas
Regens are just fun. What other total receiver can offer demod of AM, CW, SSB, and FM in a pinch through slope detection with a single active device?! Sure, they're finicky, but perfect for us old

Locked Re: Regenerative receivers and loop antennas
Good question Ottavio, The thing that comes to mind is that with regens strong signals can injection lock the oscillator. Feature or bug depends on usage. Good for AM usually but not for CW or

With two ( the same preferably) and a phaser unit one can do some interesting things.. Ideally not using mla30¡¯s but better units.

Thanks.? However, I have the dx, not the duo.? It is interesting, though, what two receivers can do with "diversity." My question pertained to two antennas, not two receivers. I guess the point is

I have 2 MLA-30 receive antennas.Is there any configuration that would enhance reception by combining them, e.g. by using a splitter in reverse (combiner)?Either 90 degrees to each other or parallel

"The Nylock nuts are very good for moderate temperature applications." My rule of thumb is "people temperatures", and no Sun. I've had the insert crack due to cold, and UV, on very rare occasion

Hi Marcus, OK all understood. I also use the same network with a Skanti Marine HF transceiver. The receiver was intended to be used with separate TX and RX antennas. Probably just a 12ft whip on

Thanks Martin; Here in SA we don't have the BC overloading below 10MHz. Several MW stations was turned off last 2 or 3 years so I even removed a 4 frequencies MW BC trap I did for a KiWi that shares

Locked Re: RLC Network for ITU noise curves compensation
No problem. The amount of attenuation, and the curve that it follows, generally needs to be adjusted to suit the antenna in use. But the values I have shown tend to be a good compromise and will
