Euros
USA $6.75
3)
Resistor kit for 630m amplifier
Resistor kit with R1 - R11 and
R14 - R37.
With some suppliers asking you to buy
10 of each value, this option may save a lot of unwanted resistors.
Note this does not include the 2 high
power 10 Ohm 20W resistors R12 and R13.
Due to high shipping costs, This
option pack is only available when ordered with a PCB.
UK £2 Europe 3.00 Euros USA $3.50
4) Complete
kit of parts for the 300W 630m Amplifier. Details

Also MOSFETS power resistors
low current LEDs etc. + Transistor mounting kits for the MOSFETs and M3
screws for mounting the 20W power resistors.
UK £69 plus £3 post and packing. Europe 87 Euros + 8 Euros airmail shipping. USA $98 + $12 Airmail shipping.
5) MF
/ LF 5 Watt linear amplifier. Details
Designed
for transceivers that produce a low level RF signal, this 2 stage amplifier
typically generates 5W from an input of +6dBm.
With a bandwidth covering 80kHz to 2MHz this initial batch of kits is supplied
with a low pass filter for the 630m band.
Cost Including
shipping: UK £20.00
Europe 26 Euros USA $31.00

Double tuned circuit followed
by a JFET amplifier and bipolar buffer.
2 x Toko SMD coils,
semiconductors +
resistors, capacitors etc.
This pre-amp is now available assembled
and tuned for 136.5kHz or 472kHz @ £16 + £1 p+p (UK)
or 23 Euros / $28 via Paypal for Europe or USA including 1st class airmail
postage
9) LF Preamplifier
blank PCB.
Make a LF or MF preamp for a
frequency of your choice from the wide range of Toko SMD coils available
from suppliers like RS
Components. PCB is double sided 50mm x 35mm
Pre-amp PCB £6 / 9 Euros / $10 inc post.
10) 2.4
GHz signal source kit 2010 design.
Details
This little
circuit is a comb, or harmonic, generator. It uses a 3rd overtone
crystal and a PIN diode multiplier to
generate a series of spot frequencies
across the microwave spectrum. Useful for
aligning S band receivers and
checking the radiation pattern of antennas. - I
can even hear this on 10GHz.
A full kit of parts, including a crystal is available from AMSAT-UK Kit £15.00
(A-UK members price)
Amsat-UK accept credit card orders and will
ship worldwide
All kits have a PCB with screen printing and
plated through holes.
11) - A narrowbamd 2m preamp kit
including 2 x surface acoustic wave filters. Gain 11dB noise figure apx 1.5dB.
Details including downloadable pdf from the AMSAT-UK shop.

Post and Packing
For orders of components, postage is based on the overall weight of the package.
Standard first class post is used within the UK. Recorded delivery is used
for orders exceeding £50. Insured post is available on request at extra cost.
Orders outside the UK.
Airmail is used as standard. This service is not recorded or
'traceable' but has proved very reliable. With 300+ packages sent to mainly
western countries over ten years+, not one has gone astray. However international recorded delivery
or an insured service e.g. UPS, or Fed Ex can be purchased to countries where this is
available.
Payments from outside the UK may be made via Paypal in Euros or
US Dollars
