On the other hand, it has no RF output capability which is a major drawback for its uses.
Proper combination of conventional radio front-end along with low cost SDR hardware enables us to create higher performance radio with software flexibility. Although we have these features in conventional radios, we do not have any software flexibility as in SDR systems. On the other hand, conventional radio rigs have strong channelizing input filters, including low noise amplifier, antenna protection and other signal conditioning circuits. When we consider SDR as a digitizer hardware which consists of mostly digital circuits, we may have performance issues due to weak analog front-end. With low cost SDR hardware and its open source software supportwe can set up a high performance radio station at home even using a personal computer. So you have the best of both worlds - the traditional control via the VFO button on the radio as well as the comfortable operation via the computer. This makes it possible for the transceiver to be controlled by the waterfall of the SDR program and always display the correct frequency.Īll this while the Icom transceiver with all its functions remains the same as before. The installation only takes a few minutes, and a dismantling without residues is possible at any time without problems. The current consumption is only 30 mA, leaving enough power for the external tuner. The power supply of the buffer amplifier of the PTRX is provided by the Tuner connector, which is also looped through. The RF signal is picked up and looped through via an existing plug connector on the circuit board here, too, nothing has to be soldered. The additional IF output is mechanically very stable and inconspicuously fixed without having to make any permanent changes to the Icom transceiver. A milled aluminium angle is used instead of the tuner socket of the IC, which is routed to the outside with the supplied cables. The PTRX board is professionally manufactured and equipped with high-quality components. Not so with the PTRX! Due to the careful design of the circuit, the tap of the IF signal is high-impedance and therefore does not load the receiver of the IC at all, the receive level remains the same.Īnd in the case of transmission, the attenuation is high, typically better than 60 dB. This attenuates the level of the received signal by up to 3 dB.
Other solutions to add an RX output to a transceiver simply pick up the signal without worrying about impedance adjustments.
All cables needed for the installation are included, the installation is described in detail and with pictures. Nothing is permanently modified on the transceiver, soldering is not necessary.
Trevor wall (twall)Īnd the best thing is: This pan adapter is very easy to install and, if necessary, just as easy to remove. The RX of the is not affected because the adaptor uses precise impedance matching of the receive signal. So the remote control of the IC gets a completely new dimension. A panorama adapter for the IC? Right, but unfortunately the IC has no output for an external display.
