Mountain topper QRP tranceiver
First: YES I do suck at Morse .. :-)
I made a Mountain topper QRP tranceiver from LNR Precision.
It is a 3 band [20,30 and 40] Morse tranceiver with about 2 1/2 Watt output. A nice small and handy tranceiver to take with you.
After the build it was testingtime so I made a sked with PA0ASD for a qso on 20 meter in morse.

Bletchley Park is an estate located in the town of Bletchley, in Buckinghamshire, England, which currently houses the National Codes Centre and the National Museum of Computing.
During World War II, Bletchley Park was the site of the United Kingdoms main decryption establishment, the Government Code and Cypher School (GC&CS), where ciphers and codes of several Axis countries were decrypted, most importantly the ciphers generated by the German Enigma and Lorenz machines.

![7MHz cw - am transmitter
I made a simple cw/am transmitter for 7 MHz [hamradio]
The design is from Nitin VU3GAO.
Just one tube [EL84] and you are on the air.
As a modulator for AM I used a TDA2005, just one section because its a stereo amp.
To finish it off a boxed it in a cabinet I had on the shelf.
Hamradio is always fun :-)
