A mini usb "breakout" would be nice for uploading new Raduino sketches without opening up the box. Could double as a CAT control interface.

I use the RD15HVF1 exclusively so i don't need to worry about multiple parts.  The gain of both parts is very close and they are pin compatible.

I would think they are a reliable source also.  Unfortunately they are no-stock on the RD16HHF1.  RD15HVF1-101 may work.  Anyone care to comment?

My assumption is RFParts is a reliable source.  That's where I've gotten mine.  Given my employment with a semiconductor company that makes (competing) RF parts, I rarely go near ebay.

Yes.  This part is particularly prone to fakes.  It would be helpful if folks could post both reliable and unreliable sources for these.

Careful with those $0.85 RD16HHF-1's
Often some random switcher FET with fresh paint.
Google "fake RD16HHF"

Maybe a shift to Mitsubishi RD16HHF-1 MOSFET is worth a try. ...  They are everywhere from $5 each here in the US to US $0.85 (China) in lots of 10.
