Minimum Discernible Signals - noise is generated inside the radio from the amplifier stages and how much amplification is available in the receive chain to bring a signal above the radio’s internal noise floor As sensitivity increases, you can degrade dynamic range To measure, start by injecting weak signals until you observe the signal level out of the speaker roughly double in amplitude (3dB) Lower values are better (bigger negative number), allowing you to detect weaker signals Most HF radios are between -125 to -130 with -135 to -138 being on the higher side of performance Noise Floor The internal noise figure generated by the radio with the antenna removed Dynamic Range Strong Signal Handling - how does the radio perform when there are strong signals adjacent to where you are tuned? IMDR3 - Intermodulation Dynamic Range When multiple strong received signals overload the first receiving amplifier in your radio, the signals get clipped When the radio has a broad banded receiver, this clipping begins to act as a mixer and creates intermodulation showing up at different frequencies Additional unwanted signals are created in the receiver when multiple strong signals are present To measure, begin with two signals apart - the difference between the MDS/sensitivity and the level required to set the signal generator to to cover up the weak signal Higher values are better - 90dB range above noise floor is average, mid 90’s to 100 dB is on the higher side of performance Blocking Dynamic Range A strong signal overloading your receiver thereby reducing the gain of the receiver. Receivers can have challenges when a strong signal is physically near the radio To measure, inject a signal until it causes receiver overall gain to drop one DB Higher values are better - typical better than 130dB of BDR, mid 130s to 140s is on the higher side of performance Phase Noise An indication of the quality and “cleanliness” of local oscilator (VFO, or Crystal Master Oscillator) Denotes whether they introduce jitter or noise to the received signal Lower is better Reciprocal Mixing Dynamic Range (RMDR) RMDR is tied to phase noise Impacted by how clean your oscillator is To measure, listen in 500hz bandwidth and measure how strong an injected signal has to be to raise the noise floor on the freq you are tuned to (1-3dB noise floor increase) This ratio is the RMDR Higher values are better - 110-115 dB As multiple signals get closer, the RMDR drops Sherwood Engineering Receiver Comparison List - http://www.sherweng.com/table.html

In the last couple of episodes we have talked about Arduino shields and breakout boards. In this video, we will review a specific Arduino shield that makes developing projects and debugging sketches on the Arduino extremely easy - it's called Dr. Duino.Arduino Shield for Arduino Shields The Dr. Duino is an Arduino Shield. As would expect, it fits snuggly on top of the Arduino headers and has pin headers of it's own, which can easily accept a shield on top. The first thing you notice about Dr. Duino is that it's built like a doughnut - it's got a giant hole in the middle! (FYI - It does not taste like said pastry…) There are a couple reasons for this form factor, but foremost is that even after you stack another shield on top of Dr. Duino, you still have easy physical access to all its resources. Dr. Duino Hardware Resources What resources are we talking about? Dr. Duino has 4 momentary pushbuttons, 5 LEDs, 6 potentiometers, an RS232 connector, and a bunch of access points for 5 volts, 3.3 volts and ground, oh yeah, and a siren (piezo buzzer). So how do you access these resources and why would you even care to? Both great questions! The core feature that allows us to use all the hardware I just talked about are groups of three “jumper” pins that surround the board. Almost every pin on the Arduino is associated with a set of these jumper pins. The middle pin is connected directly to the Arduino pin. The pin on the left is connected to the pin header on top of the Dr. Duino. The pin on the right is connected to the one of the hardware resources on the Dr. Duino board. With each set of these three jumper pins we get a plastic encased "jumper" - it fits snug on top 2 pins, and electrically connects them together. For every Arduino pin that has associated Dr. Duino jumper pins we have 2 decisions: 1) We can route the Arduino pin to the shield above by connecting the center pin to the jumper pin on the left. This passes the Arduino pin directly up to the shield if you have one attached, bypassing the Dr. Duino. 2) Or, we can route the Arduino pin to the resource on the Dr. Duino shield, bypassing the shield above. Each pin has a different "resource" or piece of hardware that you can use. Here is a quick mnemonic for remembering how to place the “jumper” on the “jumper pins” – Left goes Up (to the shield above), Right goes to Down (to the Dr. Duino). Digital pins 5, 6, 10, 11, and 13 have LEDs attached. Digital Pins 7, 8, 9 and 12 have momentary pushbuttons attached. Analog pins A0 - A5 have potentiometers attached and digital pin 3 is attached to the piezo buzzer. All these asset are extremely helpful. For example, let's say I am prototyping with a motor shield. What I want is for every time I press a button, then a servo moves 180 degrees. Instead of having to bust out a breadboard and jumper wires, I simply move a jumper on the Dr. Duino and I now have a preinstalled button. As long as the shield is not using that pin for anything, it's fair game to route that pin to the Dr. Duino. Or, maybe I want to turn a potentiometer to get the servo to move. Once again - scrap the breadboard - just move a jumper on one of the analog pins and you have a built in potentiometer - in fact, every analog pin has its own dedicated potentiometer! Trying to put 6 potentiometers on a breadboard and run jumpers is a major pain - having these built right in and so compact is great. Potentiometers are great for simulating sensor inputs too. Say you are developing a project that lights up LEDs based on inputs from a pressure sensor - but you don't have the sensor yet. No worries - just use the potentiometer built in to the Dr. Duino to simulate the input from the pressure sensor. Another great resource is the piezo buzzer. Most of us get used to using the serial window to debug our sketches. For example - we use the Serial .print() function to send a value to the serial monitor window when some threshold is met. What this ends up doing is dividing our visual attention from the Arduino to the computer monitor. With the piezo buzzer, you can get the same information, but be able to look at your Arduino - it allows you to incorporate more of your senses into the debugging process. All of these features add up to a great little development package - it's like a breadboard full of components all connected on a handy shield. So if I am traveling I don’t have to pack away a bunch of pieces-parts, I can just throw the Dr. Duino in with my Arduino and go for it. A Tool for Learning Arduino Code Another great use of these resources is when you are learning to use Arduino. If you are really trying to jump right into the code, then setting up the circuit can sometimes be a hassle, even if its just a button and an LED. (Yes - I am that lazy!) With Dr. Duino you can work through practically every sketch in the examples section of the Arduino IDE with only some minor code changes (mostly pin designations changes), without having to add a single piece of hardware. That’s a time saver (especially when it’s hard enough to carve out time to learn). Especially if having to place the components just feels like another barrier to practicing your Arduino coding. A Debugging Tool So far, most of my love for the Dr. Duino has come from this development aspect, but the Dr. Duino has actually been designed to help you debug your sketches when using shields. Microcontrollers (like the Arduino uses) are truly at the threshold of hardware and software. The more you know about both the physical and virtual, the better off you will be. Here in also lies a challenge – you can screw up both the hardware and the software. A big part of debugging your work is tracking down where the issue exists – is it the copper or code? (Or both !@#$) The Dr. Duino’s key feature of being able to direct an Arduino pin to or away from a shield you are using enables you to more quickly establish the starting point of debugging. Once you master how the rerouting works, the Dr. Duino will be a go-to shield for developing and debugging. With such a diverse set of applications it’s no wonder Arduino continues to grow wildly popular. Shields like the Dr. Duino make it that much more fun to use Arduino as a rapid prototyping tool. Special Bonus If you are interested in getting your hands on a Dr Duino, you can buy them directly from the Dr. Duino website. The creator of Dr. Duino (Guido Bonelli) has been kind enough to offer Open Source Hardware Group readers a free shipping code. Free Shipping Code: OSHWG_RULES (So true…)
