Author Topic: I'm now running a QRP station - FINALLY!!!  (Read 8250 times)

I've been off the HF bands for years.  I got psyched up after attending Field Day with a group of guys.

I cranked down a recently purchased Ten-Tec Century 21 and I'm feeding it into a W3EDP antenna.  First contact was about 273 miles at about 2 1/2 watts.  I'll take it.  Now that I got a couple of kinks worked out of my station I'm running about 5 watts.

CW at QRP power is a blast so far.  I've been wanting to do this for years.  Like I said, FINALLY!!!

Congratulations! The Century 21 is a fine rig. I think you'll find that 273 mile QSO just the beginning of many enjoyable QSO's. Good luck!

Great!  That Century 21 is quite a good CW rig, nice sounding and it's possible to repair it, either yourself or through Ten Tec.

For portable use I eventually want to build a QRP xcvr.  Any suggestions for a first kit to build (xcvr or other)?

Re:KA0HVE
A lot depends on TYPE of portable ops that you intend to do. For typical sunny patio/park picnic table weekend ops the relatively larger and more fragile rigs like a K-1 or Weber tri bander are ideal. For more exposed rough and tumble ops like backpacking, operating from canoe/kayak, the smaller and rugged single band rigs like the MFJ Cubs are better suited. Experience quickly taught me to leave my K-1 at home or at most a nice sunny day portable out in the back yard screen house.

I really like the SW40+ series for backpacking:  small, cheap, light, and easy to use. 
After hauling my old Argonaut (which is light but takes up a lot of space) and HW-8 around
in my backpack I found that, even with multiple bands available I mostly worked 40m anyway.
I've tweaked the receive current down below 30mA so it is fairly stingy on battery power,
which helps to reduce the total weight.

How about a NorCal 40a?  It was my first kit and I managed to make it work.  The kit was top notch and not too difficult to build.

How about something nice like an Elecraft K1?

Great rig the Century 21. Had a new analog version many years ago. Don't forget the OHR series of mono-band QRP kits.

Could anything be easier than this for a first transceiver kit? Incredibly low parts count.

I'm still getting used to QRP.  Iowa to Maryland using 5 watts and a marginal antenna!  Incredible.

Fine on your operation with the Century 21.  Since you expressed interest in building a QRP, here are a couple recommendations --

1. Single Band 40m -- Cyclone from 4 State QRP Club.  Nice performance and excellent support during build.  Rig is about same size as a paddle, 5 watts output and tunes entire CW band.  Stable after short warmup. 

2. PFR-3 or Hendricks Tri-Bander from QRPkits.com -- these are multiband rigs, a bit more complex. 

If you don't have prior soldering experience, I suggest a simple warm-up project -- 4 state QRP has a nice electronic keyer for example, or a nifty NESCAF audio filter from NE QRP club.

The Cyclone sounds really good according to some reviews.  I wonder ...   Grin

Hello,

I'd suggest a KX1 because of the DDS VFO. You can't go wrong with any Elecraft kit.
The KX1 can receive short wave broadcasts as well, which the K1 can't.
I have a K1 and I love it. A bit drifty while warming up, but stable after 10 mins.
The advantage of the K1 is slightly more power, a better ATU and a speaker.

Gil.

Hi Dan,
Glad to hear you finally got that old Ten-Tec on the air. Let me know if you want to set up a sked sometime. 73
