Tenner - QRP CW on 10m

This rig is many years old. It is simple, but it worked lots of DX. 

As I recall, it produced about 500mW of CW.

10m Tenner Transceiver

This was created before the last sunspot peak. Although many have migrated to FT8, nothing beats working DX on a simple transceiver that you have made yourself. 

Although you made not build this, I hope it gives you some ideas.

The Tenner transceiver

Hopefully, this will spark some ideas. I build this rig on the up-slope of solar cycle 24, but with cycle 25 now in good shape, it should be capable of plenty of DX with simple antennas. It worked plenty of DX.

10m Tenner transceiver

With the Es season just starting in the Northern Hemisphere, perhaps now is the time to think about rigs. Some years ago I designed and built the Tenner which is a 500mW CW transceiver for 10m.

During the Es season, you should have no trouble at all working stations 1500km away with it. In the past, it has got far further!

10m Tenner QRP CW transceiver

This design is now quite old, but it goes to show that things do not have to be complicated to work. It was derived from my Pipit 15m transceiver.

As 10m is getting good again and the Es season is approaching, this  may give you some ideas. I am sure it can be improved, like most of my ideas!  If you build one, be prepared to experiment.

Some years ago I designed and made the Tenner transceiver for 10m CW. It produced about 500mW but gave me loads of contacts with just a low wire dipole. As 10m starts to get better as we climb cycle 25, this could be increasingly useful.

Tenner 10m QRP Transceiver

Before the last sunspot maximum I designed and made the Tenner 500mW 10m CW QRP transceiver. Especially in Es openings this is capable of plenty of contacts. It has crossed the Atlantic Ocean several times.

Tenner 10m transceiver

Many years ago I designed and made a simple 500mW transceiver for 10m CW. Much DX was worked with it. These days I have not used CW for a long time. It was VXO controlled and used a direct conversion receiver.

The Tenner 10m CW QRP transceiver

Apart from summer Es, 10m is not the best DX band. Give it a few years, it may be quite different and 10m DX should be easy with QRP.

Perhaps now is the time to get building. Remember that all of Europe can be worked with QRP every May, June and July. Once the F2 openings really get going the USA should be workable with QRP regularly. In both cases, just a low wire dipole is all that is needed - no beams, nothing big in the air.

Tenner - a 500mW CW transceiver for 10m

This was a rig I built and used a few years ago for 10m CW.  As you can see, the design is simple but it worked across the Atlantic many times. Pull the crystal too much and the RX-TX offset becomes too great. Ideal as a simple rig for 10m CW.
