Description

FrSky Tandem X20 R / X20 RSTD ISRM PRO RF PERFORMANCE With solid performance based on the dual band 900M 2. 4G RF signal link with multiple operating combinations of RF modes, the TANDEM X20R & X20RS versions are equipped with the TD ISRM Pro built in RF module which is capable of supporting multiple protocols (like TW (Twin), TD (Tandem), ACCST and ACCESS), with same RF capability as X20 Pro editions. The TD ISRM Pro RF module has the dual 2. 4G TW RF mode and supports

TD-ISRM PRO RF PERFORMANCE
With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations of RF modes, the TANDEM X20R & X20RS versions are equipped with the TD-ISRM Pro built-in RF module which is capable of supporting multiple protocols (like TW (Twin), TD (Tandem), ACCST and ACCESS), with same RF capability as X20 Pro editions.

The TD-ISRM Pro RF module has the dual 2.4G TW RF mode and supports simultaneous activation of working under TW and ACCESS R9 modes with the same module. In this configuration, the TW receiver and ACCESS R9 receiver can be connected via the SBUS IN/OUT ports to achieve redundant backup. This RF signal connection solution makes use of three different RF links at the same time in RC applications. This further enhances the transmitters signal reliability, particularly in long-distance RC operations scenarios.

DIFFERENCES IN APPEARANCE & FUNCTIONAL INPUTS
The X20R and X20RS have changed from the original X20 design in appearance. The bottom hand grip adopts the overall design of the PRO version, eliminating the need for an additional grip cover, and allowing the lower portion to be fully grasped by the palm for a more comfortable and relaxed grip. Additionally, the Lite-type external module slot has been adjusted to provide a better fitting installation space for external modules of different shapes, making it more convenient.

The R and RS versions add 2 extra trims, allowing for increased precision tuning during  operation. The slider levers on both sides of the transmitter support adjusting the positioning of the center, catering to different users' habits and preferences. The primary input components, including trim caps, center-slider caps, and the knobs are all made from metal, offering rugged quality and enhanced durability for outdoor use.

UPGRADED ROBUST ANTENNA HANDLE & EXTERNAL LoRa ANTENNA CONNECTORS
The newly upgraded antenna handle provides better impact resistance helping the transmitter withstand the tough conditions of outdoor fields. The reinforced and thickened antenna casing provides better comfort and grip, while not compromising the antenna's performance. On the contrary, the redesigned antenna can transmit signal data more effectively, providing pilots with a robust radio link with their aircraft.

The X20R & X20RS are also equipped with 2 external antenna connectors, which can be mounted with additional 2.4G and 900M antennas for enhancing the RF capabilities working under the LoRa modes, to achieve enhanced long-range control.

BUILT-IN MASS STORAGE & (RS) TEXT TO SPEECH FUNCTION
To save the user the trouble of deciding the storage capacity, both R and RS versions have a built-in 8GB flash storage that offers big storage to meet all your radio's storage needs with high data transmission speed.

Thanks to the upgraded storage feature, the TTS (Text-to-Speech) function of X20 RS versions can quickly and conveniently convert typed input English words into spoken speech. This enables the ETHOS system to more flexibly match the triggered operational status using generated speech audio when specific functions are activated and to alert clear outdoors with the digital power amplifier module.

(RS) DUAL-SIDE HAPTIC GIMBAL FEEDBACK
The gimbal vibration feedback function can be easily enabled or disabled by setting a switch. The dual-sided Gimbal's vibration feedback can operate independently, allowing the configuration to match distinct feedback preferences tailored to various application scenarios for RC enthusiasts.

EASY TRAVEL-ADJUSTABLE MC20R GIMBALS (with ANY DESIRED DEGREE BETWEEN 45° to 60°)
The MC20R Gimbals also have an 8° rotatable panel and can be adjusted to a 45° travel position. What's even better is that the angle is not limited to just 45° and 60°, the MC20R Gimbal allows for adjustment of any travel position between 45° and 60°. To enhance convenience for pilots in outdoor applications, the angle travel position can be directly adjusted using a 1.5mm hexagon screwdriver through the adjustment hole on the Gimbal Panel, eliminating the need to disassemble the radio casing.

Info not to be found elsewhere ...
Format: Paperback
I am a cardiologist in my 50s. I have long been interested in hemodynamics and have an extensive home file system and library of Cardiovascular related books and journal articles. I thought I understood hemodynamics and tracings very well. However this book is a treasure trove of info that simply cannot be found in other publications. It has been a very worthwhile purchase. Highly recommended. This is best suited for cardiology fellows and beyond in my opinion. This info is simply not to be found elsewhere. It is as if a grey haired attending is pointing out minutiae to you that you had not realized was buried in the tracings. Well written and easy to digest. It is best to have a good understanding of hemodynamics and waveforms before reading this though. The correlation with ECHO and diastolic issues is also very good. (This book should be required reading for all cardiology fellows - invasive or noninvasive)

Excellent
Format: Paperback
As a second-year cardiology fellow, I used to get very confused with hemodynamics during my cath and CCU rotations. This book is a gem, it is clear and logically written, has great explanations of waves and great illustrations. The constrictive pericarditis, valvular disease, and FFR chapters are impressive with echocardiographic and physiologic correlations. I actually liked everything I read, like the nice differentiation between the pressure tracings of various chambers. Some of it requires multiple reads but it is worth it. I realized that I had missed a great deal of the basic understanding of pressure tracing configuration, wedge pressure, shunts. There are also over 50 cases in a test-answer format probably covering and reviewing most hemodynamic topics. It is like 2 books in 1.

Bought this book. Good content. However my copy is in black and white. There are references to colored arrows. I later learned that others have a colored copy.

AMAZING BOOK!!!!!
Format: Paperback
AMAZING BOOK!!!!!! WOW!!! everything you need to know about hemodynamics. This book explains the concepts with graphing, images. It also summarizes the key points. I wish I have read that book sooner. I could not believe it that in 1 book I found all the information I needed for the cardiology boards and my daily practice. Thank you o ugh Dr. Hanna for taking the time to write this book. Much Thanks!!!!
