3/29/2024 0 Comments Bias amp 2 pttThis is my actual LNB/POTY design for holiday usage. The relay works with 28V so the level has to be adapted with 2 transistors to fit the range of the transceiver. A microwave coaxial relay will do the TX/RX switching of the down converted 70cm signal for the transceiver interface. The SDR Console is locked to the IC-9700 by OmniRig 2.0 so the VFO setting of the TRX changes the frequency on the console and vice versa for mouse access.Ī small fan is always running at 6V, in case of temperature rising above 60 degrees a temperature switch will increase the voltage to 13.8v for full cooling. This is optional for a larger panafall display but not neccessary to do qso's. For reception with the pc you have to connect an USB cable to access the built in RTL-SDR stick with 0.5ppm TCXO. There is an extra 10 Mc output to sync the TRX if desired. Instead of providing a fixed number of amp models, BIAS Amp represents an entirely new concept: you can virtually design your amps, match any tube amplifiers, and share or download thousands of amp models from ToneCloud. 25.7Mc) and two cables to your UHF transceiver, in my case an Icom IC-9700. The modified SG Lab PA with extra hole and thread for the feedthrough capacitor to get the forward power for the meter.Įverything is in the box, you only have to connect three cables to the LNB/Feed (RX 10G, TX 2.4G, Ref. This is the complete all-in-one-box solution for Oscar-100. The p/s consist of 2 step down converters for 5V and 12V and a 150W upconverter for the 28V for the final amp. and with 2.4GHz cavity resonator and 20W power amplifier from SG-Lab. The upconverter is the BU-500 from HiDes modified for ext. The transverter is fully transceive on 70cm (RX/TX) and has an additional TCXO-RTL stick with the SDR-Console from Simon Brown for full duplex operation.Īll frequencies are GPS synchronized with 2 Leo Bodnar GPSDO units at 10Mc and 25.7Mc for the LNB.
