The other with 223 MHz signal for down converter from 739 (LNB) to 70 MHz (739 MHz – 3 x 223 MHz = 70 MHz). One RFzero generated 25 MHz for the reference signal to the LNB. I used two RFzero and made a mixer (ADE-1) and a diplexer (OZ2OE), so I could listen on my Icom IC-7300 on 70 MHz. This was my first approach to listening to the QO-100 satellite. I had to put the antenna outdoor so the GPS can get reasonable signal and short time to first fix (about ½ minute). When I switch on the transverter a DC output is activating the interface and RX and TX signal goes to the transverter. Kuhne DB6NT transverter interface in place in my IC-7300. This is a cheap China board with a SPF5189Z The output from my transverter interface was very low (8uW) so I had to add an amplifier to the 70 MHz signal. It is unfortunately not available for sale, it is not come to a production phase only some prototypes exist. The transverter board (to the left) is a prototype V0.2 made by Steen, OZ5N. TX: Switch for switching the power for the TX.Trans: Switch for activating the transverter interface in the Icom IC-7300.Not finished the TX part yet on the picture. My homemade transverter for the QO-100 satellite.
#HAM RADIO DELUXE IC 7300 TV#
The cable from my shag to the TX box is cheap 75 ohm TV cable with F connectors.
#HAM RADIO DELUXE IC 7300 DRIVER#
The box contains a driver (ADL5324) and cheap Chinese WiFi PA stage (8W). Now I added the TX antenna which is a 2.4 GHz antenna from a wireless Internet installation. So when my radio is showing 70.200 MHz, I am receiving 10.489,700 MHz and transmitting on 2.400,200 MHz.įor receiving I use an old 85 cm TRIAX, from the days when we received TV via parabolic antenna. Here you can read the needed frequencies for different output/input combinations: Option The RFzero QO100 SW is capable of switching one of the frequencies between RX and TX, but this is not needed here, the two frequencies are chosen so the RX and TX use the same inject frequency The idea is to have two fixed GPS locked frequencies, one for the LNB and one for the transverter action. I prefer to run it on 70 MHz on my Icom IC-7300. His transverter can be adjusted to use at lot of IF frequencies. The design of the needed frequencies is made by OZ5N. Here a description of a two port LNB modification and how he runs it with a RFzero, made by OZ1BXM.
#HAM RADIO DELUXE IC 7300 HOW TO#
You can read how to do this here, this page is made by OZ2OE and is in Danish.
I have modified mine for external reference frequency (25 MHz). Unfortunately it is not available at the moment (dec 2019). The LNB is a cheap item from a danish ware house Harald-Nyborg (59 Dkr), it is a Maximum ST-11 #5650. The same signal is used for upconverting the TX signal.
