Rock-mite 40 QRP kit. Good 'n' ready!

Another one QRP kit found it's way to the rack!

I finished the construction of it yesterday by winding T1 and T2 toroid transformers.

Pout is approximate 2W. Me thinks that more power than that it is rather unobtainable judging from the characteristics of the output transistor the size of the heat-sink and the turns ratio of the transformers.

My personal advice to any one of you thinking to buy it, is to do it! It will give you a pleasant frustration decoding the Chinglish during construction and then you will award yourself with a small but remarkable rig!

Cheers!

The saga continues!

Rock-Mite 40. The saga* continues!

0(zero) Ohms resistor? Well, it's look like the prefect conductor to me!

More components populated the rock-mite board up to the last two T1 and T2 toroid transformers.

*saga. any piece of writing that tells of heroic events or deeds

Rock Mite-40 QRP kit

Spring is coming so I decided to rejuvenate my mood after a long idle winter, by building a rock-mite 40.
The kit bought from China (where else!) and it came the typical Chinese way. An envelope containing a plastic bag full of components. No manual, no instructions other than "you friend go my site. you read manual weld kit enjoy afterward"!

I promptly done that and "reading manual", I found a lot of mismatches between the schematic diagram and the components values in the component inventory.
For example R3 on the schematic has a value of 0(zero?!) Ohms whereas in the instruction leaflet has a value of 220Ohm.

Nevertheless I bite the bullet and I started the construction.

As usual I started with the smallest components ie the capacitors and I continued with the resistors, mounting almost all of them on vertical position.
I'll let you know the progress.
