Review Summary For : WA3RNC 40 Meter Crystalplexer
Reviews: 1MSRP: $40
Description:
The Penntek Instruments 40 Meter Crystalplexer is a low power crystal controlled QRP transmitter offering a significantly improved tuning range when compared to the usual crystal controlled unit. A fundamental 7 MHz crystal in VXO circuit might be able to be “pulled” just a few hundred Hertz. That’s better than no tuning range at all, but is still very confining in terms of frequency coverage. The tuning range of the Crystalplexer is greater than 25 kHz! No more endless CQ’s on your fixed crystal frequency. Stability is excellent because crystal control is maintained. Power output is adjustable from less than 1 to more than 3 watts. T/R switching permits QSK operation. The board is supplied with 56 SMT parts already installed. You add another 27 parts, and you’re done. It’s really a quick build! This transmitter meets the current FCC requirements for spectral purity with harmonics and spurs at -55dBc.

Great little Kit Time Owned: 0 to 3 months.
I bought this to use with an old Drake 2B Receiver not knowing how well it would work. It went together in about 2 hours or so, the most time consuming part was winding the 5 coils. It fired right up first time, peaked the transformers and then set to power to 3 watts. Hooked it up to my antenna and the 2B and was amazed at its performance. The cw keying sounded good and the qsk is amazing utilizing its built in TR switch.


I made a couple quick qso's with it and received super good reports on the tone and stability.


Great little kit and lots of fun to play with.
