High Performance and No Compromise CW Transceiver with fully modular
architecture.
Project
Product
Description ( updated Jul
2003)
Easy to Build:
- Controls
and connectors mounted directly to boxed and shielded modules.
- User
manual with step by step instructions.
- Incremental
assembly and test.
- Totaly
modular, flexible and upgradeable architecture with replaceable
shielded boxes. Easy to expand to another bands, upgrade the filters,
VFO, or build-in an options etc. Camper
1 tcvr will grow easily as Your baby!
- No
surface mount devices.

Highest
Performance and No Compromise CW Base
Unit
General
Features:
- Efficient
10-16 volt operation for home or field usability.
- Low
receive current (no back light, pre-amp off, headphones).
- Full
break-in CW - Diode T/R switching.
- 5W
output power for full QRP standards operation (up
to 20W output optionaly available).
- Rugged
boxes can be customize enclosured.
- Single
band is available in basic version (upgradeable
to 160-10 meter ham bands modules).
- Superior
stable and clear VFO, no spurious. (temperature
compensated optionaly)
- 100kHz
tunable VFO in basic version with clasic rotable capacitor (10
turns pot with varactor or PLL synthesized for low noise ... no DDS
spurs. optionaly available.)
- Telegraphy
frequency counter, accurate to within 1kHz, manual or auto modes –
internaly selectable.
- CW
only with no compromise performance in this mode.
- Center
detent RIT and XIT control with approx. +/-2kHz range (user
adjustable).
- Fully
SWR protected – will not be damaged when short or open circuit
loaded.
- Relative
to main carrier at 5W output, all harmonics *
dB or better, all spurious * dB
or better.
- Ready
for use with headphones (speaker optionaly).
- Headphone
jack handles mono and stereo plugs
- BNC
antenna connector -- A QRP standard. (SO-239
on High Power as an option).
- Room
for additional connectors on the front/rear panel for user
modifications.
- All
options may be added at any time.

will be done.
Receiver:
- Double-balanced
high level diode IF mixer (+23dBm) for excellent front end dynamic
range and IP3.
- Exclusive
RX/TX front-end filtering in special „Triplet“ design (LPF+HPF+BPF)
arranged for each Ham Band, relay switched (for excellent IP2 on RX).

- RX
low noise quad JFETs pre-amp and attenuator. (Both
switchable on/off).
- Single
conversion superheterodyne RX designed as a down convertor to low 8MHz
(2MHz)
IF or as a up convertor to high 36MHz IF.(upgradeable)
- Smooth,
Fast attack, IF-derived AGC (no
'popping' on strong signals)
with fast/slow delay. (AGC
can be turned off also).
- Really
sharp IF 8x crystal + 6x crystal filtering with superior stopband
rejection helps prevents receiver overload from signals outside the RX
passband which can be upgraded up to 16x
crystal + 8 crystal filtering optionaly! (Much better
adjacent signal rejection (without AGC pumping) than the switched
capacitor audio only filtering of other rigs.)
- Clasic
capacitor or 10 turns pot or PLL synth. VFO controled
- AGC
with more than * dB range.
- Low
noise audio circuits in final stages. (no LM386 etc.)

CW
Features:
- Full
break-in (QSK) CW - Diode T/R switching.
- Built
in keyer with programmable memories
and both popular iambic modes A and B (optionaly).
- Sharp
bandwidth 300Hz CW crystal filter with more than *
dB stop band rejection typicaly!
- Optionaly
fixed-bandwidth narrow crystal filtesr or a wide-bandwidth crystal
filters (up to 16+8 crystals) for tuning the band.
