Rotary Switch for SWL Receiver and AADE DFD2 Frequency Counter

Presented here are several ways to incorporate automatic switching with the AADE DFD2.

The first one, Switching the DFD2 with the Switches on the PCB, interfaces with the band switches on Board 1. Parts for this method are included in the Frequency Counter kit.

There are several ways to hook up rotary switching for the receiver and for both the receiver and the AADE DFD2. The easiest one is to use a 2 pole rotary with at least 4 positions, check out AADE DFD2 and Receiver Switching with 2 Sections. No rotary switches are included with the kit.

The first rotary schematic is for receiver switching only.

The second schematic switches the receiver and the DFD2 with a two section rotary switch. The third schematic uses a one section rotary switch but is a little more complicated to wire.

For those using the SWL version of the receiver, a three section rotary switch is used for switching the bands. Manual switching of the bands is shown in the SWL instructions.

Switching the DFD2 with the Switches on the PCB

NOTE: This is a revised schematic (date: 1/14/07). All customers who have CDROMs dated between 9/20/06 to 1/14/07 need to update with this schematic.

The base connections for the transistors have been moved from the left side of D4 and D5 to the right side between D4/D6 and D5/D7.

NOTE: D1, D2 and D3 are very important diodes and should be double checked for proper position (band away from counter) before connecting the switching circuit. These diodes protect the frequency counter PIC from 12 Volts coming from the receiver board.

If a wiring mistake was made, a transistor was bad, or any other reason, the PIC would be blown up having 12 volts on its offset pins.

D6 and D7 keep 5 volts from the counter from getting into the switching circuit of the filters and partially turning on an LED that is supposed to be off. They isolate the counter 5 volts from Board 1. If a mistake is made here, no damage is done.

The wires going to the switches from the 20/17 and 30/17 circles at the Bandpass and Crystal Filter on Board 1 are disconnected at the switches and soldered to the points labeled 20/17 Circle and 30/17 Circle on the schematic above.

There are no connections between the circles and the switches on Board 1 anymore.

The 20/17, 30/17 and 40/30 Switch labels go to the switches at the front of Board 1 in the holes labeled as noted.

This circuit is built "ground plane" style with high megohm resistors used as standoffs. You could also use a small piece of prototype printed circuit board.

This circuit is a very slow on-off switch so any type of diode and any general purpose NPN transistor can be used.

The picture above shows the switching circuit "ground plane" style soldered to the frequency counter and Board 1..

Rotary Band Switch for Receiver Only

Parts needed:

  • One 4 position rotary switch - some switches found at hamfests/stores have more positions, doesn't matter, just use the first four.
  • Two 1N4148 diodes - not critical as to type, practically any diodes will work.

    Watch out for the correct connections from the Bandpass and Crystal Filter connections. See below.

    		•

    A wider view of how it all is connected.

    The switches on the board can be removed if the rotary switch is used.

    The rotary switch has been mounted on Board 1 with two standoffs. The space between the standoffs just accepts a standard size rotary switch.

    Notice the wiring to the switch and the connections on the board.

    Another place to mount the rotary is on a piece of PCB board soldered to the bottom plate.

    Cialis holland rezeptfrei – Köln 04-Jun … One of the great things about playing a game for living is that you get to play everything. When it comes to playing an original strategy game, there are so many different rules, play styles, and card types to pick from that you're limited only by your imagination. But what about in an expansion with new cards, rules, and ways to interact? Such a game would be little difficult to play. Not mention you'd have a completely different set of players. One person would be playing as the Dark Lord of Dungeon, while the rest play as adventurers attempting to gain entrance his chambers. The Problem with Extended Play Sets: If I Get Played, Can't play Myself! I mentioned before that in real life, not all RPGs, board games, and card games are the same. For this reason, I generally want to be sure that I'm not playing an Expansion against a person who's going to play with someone else. In my experience, if you ever get to the end of an Expansion, you can't play yourself, so there's no point to a game of Extended Play before you've explored all of the new areas. But we want to get the next expansion and play with people we enjoy. Is this the right strategy? that problem? In a recent article by the great Jim Rogers, author of The Game Crafter's Guide to RPG Mechanics, he described a very nice solution. In the article, Jim details how when there's an extended play set, he plays with everyone's copy of the game. This is a nice way to ensure that everyone's game is up to date. It also makes the game more social, since you end up playing with everyone while you play your own game. However, the problem is that you'd soon be out of date. Why? Because eventually, if you're spending a lot of time playing with your friend's copy of the game, sooner or later viagra vs cialis dosage you'll also be going to different tables, and not play with the other players. Eventually, it's going to be just them and you. The key to maximizing enjoyment you get from playing with others is to make sure both you and your friend's games are well-versed, but not so that you end up playing with each other anyway. But wait! It's not always fun to play with two people! And if you're not careful, what could result from you not being careful? What could happen if the Game Master gets bored and decides Köp atarax online to start letting out that drug stores for sale in canada mysterious "LOOK OVER THERE!" or even worse, let's your players play. This is when it's important that you play with the Game Master, and not by yourself! At the same time, don't let your friend know that you're starting to be "too involved." A friend shouldn't start talking to them Diclofenac 75 tabletten rezeptfrei about how you just got to see the movie and that you just found a dragon! Don't play without the Game Master Do not play without your Game Master, and if you have friends, they should let you know that not be playing without their Game Master. So don't start off with nothing better than a few cards. But once you get going, always play with a Game Master. If you're playing on your own, please realize that this is usually fine, but if you end up playing with someone else without them knowing, please remember that you'd both be a lot happier if you were playing with someone experienced.

    The receiver has its own rotary section and the frequency counter has its own rotary section.

    Some rotary switches have two sections on one wafer. These might be cheaper than a rotary with two wafers. Also, almost all now have more than four poles, i.e. 11, and are sold as universal rotary switches. They will work fine, just use four poles.

    Remember to use an RF Choke and .01 bypass capacitor at the jumper connections of the Frequency Counter when hooking up the counter section. See picture.
