A NOVEL RF Output for ICOM IC-9700

We introduce PTRX-9700 as a novel RF output/Panadapter for ICOM IC-9700 into the HAM Radio Community.

PTRX-9700 is a type of high impedance probe with an RF output which helps you monitor activated VHF, UHF, and L band RX channels of ICOM IC-9700 simultaneously.

Installation of PTRX-9700 is totally reversible so you can remove it from your radio at anytime without any hassle. As can be seen on the actual installed unit in Figure.1-2, the operator does not need to modify his/her ICOM IC-9700 during installation or removal.  For further details on how PTRX-9700 is installed on your IC-9700, you can download our installation manual at this link. Manual de instalación en español.

PTRX-9700 comprises of three independent hi-impedance probing channels along with an active RF combiner therefore it allows the radio operator to monitor all bands of the radio without RX signal attenuation and distortion.

Design architecture of PTRX-9700 can be seen as a block diagram in Figure.3.  The RF spectrum of the unit depicted in Figure.4, 23cm (L band) signals appeared between 311MHz and 371MHz due to the internal transverter of IC-9700. 3D CAD view of PTRX-9700 is available in Figure.5, and you can find design specifications in Figure.6.

You can see the spectrum of VHF and UHF bands along with APRS  (Automatic Packet Reporting System) decoding in Figure.7-8.
