[hpsdr] Munin update?

[Dan Mitchell]

Pete;
I am driving the EB63 directly from the Pennywhistle; it takes about 2 watts
to drive it to 100+ watts. Ideally, you should have about a 10dB pad between
the Penelope (or PennyLane) and the Pennywhistle to keep the Pene in it's
optimal operating range.

Mine is the A version; they have upgraded the diode controlling temp/output
curve, and have replaced the relay in the COR circuit. (Better).

It's well priced. You also need the heat sink offered, and need to be able
to adapt it to your situation (drilling, tapping, etc.). I also enclosed
mine in an aluminum box of my own making, and fastened it to the end of my
Pandora.

I engage the xmit relay in the EB63A remotely, using the PTT OUT on the
Penny DB-25, and, since the EB63A has a COR, it stays engaged until the RF
is gone.

Originally, I used some homebuilt lowpass filters I made, with good results.
I am now using Alex, but haven't worked out the kinks in that yet.
(grounding issue or something).

There are others out there; you just have to pay your money and make your
choice, and, be willing to tinker, tinker, tinker. Good luck.

73,
Dan, W0IQ

Dan,

Thanks for the reply.  I have seen the various amps on the CC website 
but wasn't sure how well they matched with either being directly driven 
by Penelope or via Pennywhistle (or some other intermediate stage)--how 
are you driving your EB63 and what are you using for output filtering?

I'd also seen mixed reviews of the EB63 so was a bit hesitant to invest 
in it--however, it sounds like you are happy with yours.  Do you have 
the EB63 or the EB63A?  From what I've heard, it's still advertised as 
the 63 but what you get is parts for the 63A.  Not sure how important 
this is; I'd be interested to hear more of your experiences.

Ideally I'd like something that integrates well with Penelope and Alex 
which apparently Munin is designed to do--but that's not much use if it 
isn't available or isn't likely to be available for a long while:)

73, Pete, N3EVL
