QRP-MAS Projects in SPRAT

 

Dear QRP friends,

 

the QRP-minimal art-SESSION at Ascension Day is an eye-winking challenge to make qso with rigs as simple as possible. You are invited to prepare your participation with a TRX (resp. TX & RX) out of not more than 100 components (Class A) or with a TX out of not more than 50 comp. (Class B).

 

Normally you must send a circuit diagram of your station with components numbered along with your log entry. BUT: It was a pleasure to spend some sunny sunday afternoons in the garden within blooming hollystocks and humming bumble-bees and - with nearly all SPRAT issues of the last ten years.

 

The result was a list of articles describing equipment which I found suitable for the QRP-MAS.

 

If you will use a TRX, TX or RX listed here it will NOT be necessary for you to send a circuit-diagram:

 

YOU SIMPLY CAN REFER TO THIS LIST IN YOUR LOG!

 

So, instead of a drawing just tell: "RX was a Mighty Mite with 8 comp. like in SPRAT 105". Minor modifications also can be described by words.

 

My personal conclusion was to end the shadow-existence of building simple receivers and try one from the following list:

Hello readers of "Nieuwsbrief" and "OK QRP INFO":

how about reviewing your old issues and writing a similar list? I would be very pleased indeed to complete the list of QRP-MAS projects.  

 

Nice homebrewing and cuagn in next QRP-MAS!

 

(Why not making a print of this list?)

Simple QRP-Homebrew-Projects (a bibliography)

 

 Dear QRP friends,

 

 the evevenings become longer again and QRP-events like ORIGINAL-QRP-CONTEST and
HOMEBREW & OLDTIME-EQUIPMENT-PARTY are coming into sight:

 Just the right time to make you think about some simple QRP-projects for the evening or the weekend.

 

 The articles have been checked for their suitability also for the QRP- minimal art-SESSION, the SPRAT articles are given with counted components.

 

 So if you carry out one of these projects you will own something for all QRP-events - and the time between, of course.

 

 It should be no problem to change L and C for another band:

 If you need half the frequency, for instance when changing the components from a 40m circuit to 80m, you need the doubled capacity and the doubled L, which means turns x 1.4.

 Changing from 160 to 80m means double frequency = C x 1/2 and L x 1/2, whereby L x 1/2 means turns x 0,71.

 

 Now my suggestions:
