Description

618/145 MHz RECEIVING Converter Assembled in Box
To note please:
This receiving converter is not for the QO-100 satellite frequency! If you need the one for QO-100 then look at my other items and you find it there.
This sale includes the Assembled in Box
618/145 MHz Receiving Converter and Power Cord.
This is the same receiving converter as it was designed and described by
David Bowman G0MRF
in his article
"G0MRF UHF-VHF Receive Converter for use with a satellite LNB"
in open source on
AMSAT-UK
web site,
except I replaced its 595 MHz LO to the 473 MHz one. This allows us to get 10368.0 GHz (3 cm band) somewhere around 145.0 MHz.
How to use this converter ?
It is very easy.. You should have the common
Satellite TV dish
and
10 GHz (with LO 9.75 GHz) modified LNB
.
Modification of LNB represents a replacing of
25.000 MHz crystal
in the LO of
LNB
to the high stability
TCXO of 25.000 MHz
.
It is not all LNB will work there
. It needs the modern
LNB with PLL synthesizer in its LO
.
You can buy 10 GHZ MODIFIED LNB
here
Using this converter along with the
low cost Dongle SDR
tuned around
618 MHz
or
2 meters band receiver
tuned around
145.000 MHz
you can receive the signals of
3cm band (10368 MHz)
.
Its frequency conversions looks like this:
10368.0 MHz
(LNB Input) -
9750.0
MHz
(LO of LNB) =
618.0 MHz
(Dongle SDR Output) -
473.0 MHz
(LO of RX Converter) =
145.0 MHz
(2m band Output).
To note please:
Because of the high frequency of LO of LNB and a few of frequency conversions there will always be the frequency offset. You will not get exact 10368.000 MHz at 145.000 MHz. It will be somewhere around +- 100 KHz !
Inside the box is placed the RX Converter PCB board you can see on this pic.
Pinout of the connectors:
J1
-  F Connector -
IF input from LNB and +12V to the LNB
J2
-  SMA Connector -
618 MHz output to the Dongle SDR
J3
-  SMA Connector -
145 MHz output to the 2 meters band receiver
J4
-  5.5 x 2.5 mm female Connector -
Power connector +12V central pin
BE CAREFUL !
Although this converter has a protection chain applying RF power to its output might damage it. So if you use this converter with VHF radio do not push the transmit button of your VHF radio !
