Who
is afraid of SMD:s ? You should not be !
One
of the great things with assembling the QROlle is that it is
built using Surface Mounted Devices.
The normal size of the devices are "0805".
This is the CPU of the QROlle NG front. And, yes it has been hand soldered.
So have a look below and see how you do that.
Have fun with SMD:s. Why not give it
a try ?? Go out there and pick up a simple KIT and try it out. And
thus be prepared for the QROlle. For those who want to understand
how to work with SMD:s we
have linked in a video from YouTube.
-----

Here you have all the 18 coils to turn for the QROlle
mkII. Nice looking !!

Bygginstruktionerna finns här
på Svenska. |
Specifications:
- 160, 80, 40, 30,
20, 17m, SSB/CW. 10W output (variable)
- Single
IF, 5 Mhz. Similar in design as the previous QROlle.
- HF
Deck optimized for top notch performance.
- Optimized
AGC for super listening experience. See
here additional comments the constructor SM6DJH on performance.
- DDS with high
grade filtering to handle VFO-signal
- Microprocessor
control using ATMEL ARM-processor.
- Software is to
be "open-sourced" so we offer builders to contribute to software
coding. All official releases will be controlled by SM5DEH in the designer
team.
- On board programming
interface to support software upgrade when available. Standard programming
interfaces used for ease of use.
- Remote control
using USB-interface and RS232.
- Software driven
user interface with menus.
- Built in bug software
for bug and Iambic A/B
- Professional grade
Hammond case
- Only 240mA current
drawn at RX (200mA with dimmed backlight).
- Built using SMD
components. A majority of the components being of size 0805. The QROlle
Classic was built using SMD:s of the type 1206. This is one of the few
kit-type rig:s in the world using SMD:s.

QROlle "Classic" QRP-rig
80,20
meters SSB QRP-rig.
Designed
by: Olle Holmstrand SM6DJH |

The
QROlle (Classic) has been a tremendous success
and we would like to thank you all very much for the interest, feedback
and support in this project. When Olle SM6DJH and Tilman SM0JZT started
the project we could not have imagined where it would end up. No one
would imagine that we not just designed, documented and presented the
project in the SSA magazine QTC. We also got a huge interest from the
neighbour countires Finland, Denmark and Norway. We shipped 178 kits
to builders in all these countries.

QROlle Transverter
144,
2 meter band
Designed by:
Olle Holmstrand SM6DJH
Dokumentation på Svenska |

Bild
på prototypen till transverterbyggsatsen i QROlle-familjen.
Det här är
transvertern för 144
(2meter) som har varit omskriven i QTC några gånger.
Olle
SM6DJH går in i varje vinkel för att beskriva funktionen
och sprida kunskap. Denna
konstruktion fanns som byggsats till självkostnadspris. Detta
erbjöd möjligheten att bygga sig en transverter till
ett VHF-band. Fanns även
med kristall för att ansluta till en rigg med 10-metersbandet
som mellanfrekvens.
