ILER 20 QRP SSB kit received

untitledAfter a 3-week voyage across the Atlantic from Spain, my 20m QRP phone kit arrived here in the New World on Friday via registered mail and I’m very much looking forward to putting it together.

The ILER-20 from Javier Solans EA3GCY consists of 10 small bags of components, a plated-thru-hole circuit board and a mini-CD containing 109MB of documents.

Earlier versions of these kits offered an AGC circuit as an option but current versions have AGC included as part of the kit.

I’ve built a lot of kits over the years and the first thing I always look at when receiving one is the circuit board since a good judgement of the kit’s overall quality¬†can be made from it.

The ILER kit’s board is high quality with plated thru-holes identical to what you’d expect from Small Wonder Labs or KD1JV with placement location of each component being clearly marked.

Javier’s website has pdf files in both English and Spanish detailing assembly procedures with schematics and other info. The mini-CD contains these files plus a whole lot more: data sheets of many components (English), numerous QRP articles by EA3GCY (Spanish only), ILER operation explanation (Spanish & English), details of the AGC circuit and components (Spanish & English).

Especially helpful are the “inventory sessions” (Spanish & English) showing parts placement, component ID/markings, component value and the bag number in which the part is located – all in full color.

There is also a file containing a schematic diagram of an S-meter and where to connect it to the ILER for those wanting to go “above & beyond”.

English translations are excellent and that chore was obviously handled by someone who is fluent in conversational English.

    There is nothing like the smell when solder hits the hot tip on a soldering iron. Enjoy the build and do blog about the progress.

      The hard part lately is finding the time to get started…I’m sure many can relate.

    For the ILER20 Kit what is the proper capacitor value to use at C15 thru C19 in the bandpass filter? I used 12pF caps but the audio bandpass is still somewhat too narrow (<2.0KHz high end).

    I know the design was changed from 22 pF to 12 pF. I hope I didn't use the wrong values?

    I did use the correct capacitors (12 pF) but the audio is still too narrow.

    The 2 ILER40’s I built sound much better….

    Javier needs to take a look at this and come up with new capacitor values to increase the audio bandwidth (currrently less than 1.9KHz upper limit).
