K3: General Coverage Receive Filter

In my case the motivation was simple: I wanted to save the $1000+ it would otherwise
have cost me to purchase a second-hand Drake R8B or JRC NRD-545!

Now if only we could get the synchronous AM detection upgrade, I'd be happier than
a pig in poop. (Nudge, nudge...)

Mark

============================================
I'd been meaning to ask for a while; what is the motivation for those
of you who have ordered the general coverage receiver option? i.e. what
makes it worth the extra $129 ??

Re: K3: General Coverage Receive Filter

Hi Mark,

Can you be more specific? What function of the Drake or JRC could you
not replace without the general coverage receiver option ?

RE: K3: General Coverage Receive Filter

The K3 has greatly reduced sensitivity outside of the Amateur bands. The
bandpass filters are designed to be just slightly wider than the amateur
bands so as to reduce interference caused by broadcast stations outside of
them.

Well if it's the broadcast stations that you want to listen to these amateur
only band pass filters give you poor reception of the broadcast bands. The
general coverage receive option gives you a path around the amateur only
band pass filters and provides wider filters for when you want to listen
outside the ham bands. Granted the K3 has the ability to receive between
the bands with out the module but the receiver is not being used to its full
abilities unless you install the general coverage receive option.

In reply to this post by Iain MacDonnell - N6ML

The Drake and JRC models I mentioned are not amateur transceivers; they are
highly-regarded shortwave receivers. Like many others, I became a ham only after
developing a strong interest in shortwave and AM broadcast band DXing during my teens.
You know -- all those frequencies between 0.5 KHz and 30 MHz that are outside the amateur bands. ;-)
Adding the GC option to the K3 has allowed me to once again fully enjoy that hobby
after these many years. If you'd like to learn more, check out

RE: K3: General Coverage Receive Filter

Mark when you do this are you using the RX ANT jack or are you using the
standard input?

Re: RE: K3: General Coverage Receive Filter

I've been using the RX ANT jack on the AM broadcast band (makes a big difference below 1 MHz), and the standard antenna input on the higher freqs, where I don't believe there is any measurable advantage to using RX ANT.
