I will experiment with modifications to get the preselector to improve things on ten meters also. 00 Specifications. Learn more about the different options. You should do this only if you really think it is out of alignment. Radio Hardware; RTL-SDR Blog on the internet recently touted a new RTL dongle, one with improved performance over run of the mill RTL dongles. The Up-converter board basically converts HF signals to the FM band (specifically 100. Since I'm going to get a ham HF rig later this year, I'm just going to store the DX-160 away for the time being. , 1997 Motorola, Inc. 5 MHz to 150 MHz) allowing your RTL2832U to tune in the HF signals. The system shown consists of a log-periodic antenna (not on the photo), a Dynamic Sciences R1250 wideband receiver, and an Altera FPGA DSP Development Kit, Stratix II Edition. (1) Attach the 20 foot speaker wire to rear RCA or SO-239 marked "antenna in put" and connect the 18" jumper wire to "antenna out" on preselector. The design was originally published in 'Break-In', New Zealand's amateur radio magazine in Sept/Oct 2005, and is republished here with the permission of the editor. These days, most are interested in these classic Boat Anchor receives as an HF only setup. The dual down converter sections use synthesized LO inputs to convert all incoming signals to 1 GHz signal. Box 8640 Sacramcnto 22, California. Model SK 20 preselector. I am designing a receiver at present that will use the SA602 as a first, up-conversion mixer, and a second one to bring the IF down to about 300kHz. The Mini-Whip design has a frequency range of 10 kHz – 30 MHz. Radios Heathkit SB-303, 1970-1976 Solid-State Amateur receiver. cant afford to buy expensive spectrum/network analyzers so I do the eBay. 3x19x24 32 lbs shipping.
