I'm addicted to solder smoke..., so it came the new DSB QRP transceiver from EA3GCY.
Things went smooth on the building process and the final result was a pleasant to use QRP transceiver.
Main characteristics are a simple but very "hot" Direct Conversion Receiver based around the famous NE602, the kit is well engineered with a nice front-end pass-band filter and the hi-power version of the LM386 au‭dio amplifier chip. I decided to
join a DDS VFO to the MFT40 transceiver kit, I choose the EA3GCY ILER-DDS, it has some nice firmware features and it is very simple to configure and operate.
The transmitter type is a Double Side Band Suppressed Carrier with around 5 Watts peak envelope power, which is able to produce nice contacts on the 40m band even with the inherent 50% lower efficiency in relation to the SSB transmitters.
The Velleman LED VU meter is mainly for aesthetics because it only measures the au‭dio output of the receiver, but shurely causes
some glittering effect!
For the kit housing I picked up a Velleman aluminum box model G124, it is easy to drill and jigsaw.
Very nice and recommended Kits from Javier Solans EA3GCY!
