I have been studying the merits of the DXE RTR verses the MFJ-1708 some more. I now conclude that the DXE unit offers no more protection than the MFJ unit for this use. The DXE unit has a limiter but

I believe this mod does in fact exist. I know for sure because I had one on my old Omni V. The mod would definitely be a resistor change in the ALC circuit. Carl Moreschi N4PY 58 Hogwood Rd Louisburg

The IF output on the Jupiter is useless for a panadapter. The first IF is 45 mhz, the second is 455 khz but very narrow. The way to do a panadapter with the Jupiter is to do the N4PY receive antenna

There seems to be lots of confusion on the difference between NB and NR. They do very different jobs. Noise Blanker (NB) is a classic function that goes way back to at least the early 1950's. What it

Ken's description does not apply to how noise blankers work with DSP systems. But the idea is the same. In DSP systems the audio path is muted for a few milliseconds when the sharp pulse is detected.

No. CW can be handled by selecting as small a bandwidth as possible. SSB on the other hand is much more difficult. That's where all the proprietary schemes come in. Carl Moreschi N4PY 58 Hogwood Rd L
