 ====Converting a Steady Timer to a CD Cycle Timer====
 With a bit of patience and the missing components detailed in the manual, one could theoretically turn a CD steady timer into a CD Cycle/Fire timer.
-Do note however that if you do so, you must cut or desolder the jumper in the W1 position. I am curious if one may replace that jumper with a small switch to allow for choosing between steady and attack/fire signals by bypassing the extra components.

 *These devices are quite old, and excessive handling and stress seems to not play nice to the solder joints. I have fixed both the tone filters and receiver section by reflowing every joint with leaded solder.
 *Due to the XR2211A IC being obsolete and quite hard to source nowadays, I may try to design my own tone decoder board using the LM567 IC which is still available in SMD form factors. The LM567 also outputs a logic low when signal is detected, but the design will have to incorperate a LDO 5v regulator to power the chip from the 12v the cards get.
 *I have not adjusted any of the filter components on the receiver circuit yet, but I did run an experiment by leaving the device plugged in with the antenna attached inside my house while sending the activation signal from a few dense suburban blocks away. The board operated perfectly with 5W from my Anytone 878, turning on and off.
 *While the tone filters are labled J1 thru J6 on the PCB, the actual numbering is reversed, tone filter 1 is at the top and 6 is at the bottom. Despite that, my unit (and I suspect others that were reconfigured by a third party) may not start at slot 1. My unit has slots 6, 5, and 4 occupied with the corresponding wiring on the programming board. The nameplate implies slots 1, 2, and 3 however. Overall it doesn't ''really'' matter if things aren't in numerical order, but it sure as hell makes things confusing...

 The most I have discovered amounts to what I have seen regarding FCC filings from the 1986 to 1990 under the company name (under grantee code '''F49'''<ref>https://fccid.io/F49</ref>) and what I have seen in various sources of media from Google images and YouTube videos.
 The FCC ID's associated with F49 are as follows:
 *'''F49LCR-2'''<ref>https://fccid.io/F49LCR-2</ref> registered on 02/09/90 with an operating frequency range of 150-174 MHz

 My current research shows the existence of at least 2 or three types of these devices. Obviously there are more devices produced by the company, but I have zero clue what they are.

 =====Si5351 Breakout=====
 I ordered the board and when it arrived, I attached it to an arduino nano with 5v, GND, SCL and SDA (A4 and A5 on the nano). After programming the board and checking it with my new DSO, it showed 45.55 MHz as programmed using the aforementioned arduino and the Etherkit Si5351 example sketch. I removed the crystal from the LO circuit and attached the Si5351 CLK0 to the collector of Q4 as is done with the original crystal and also grounded the breakout board to the other crystal pad.
-Initial tests show nerly identical functionality from stock, even without tuning any filter components onboard. The receiver now responds to signals on 147.350 MHz, comfortably near the top of the 2 meter band.
+Initial tests show nearly identical functionality from stock, even without tuning any filter components onboard. The receiver now responds to signals on 147.350 MHz, comfortably near the top of the 2 meter band.
 With that, I taped the arduino and breakout board together, insulated, and hijacked power from the main LM7812 regulator to power it.

 Pin 13 of the IC is the RC input which is fed by a 1.1MOhm resistor and a 1uF 35v tantalum capacitor. Cross referencing those values in the datasheet chart, we get a RC timebase of ~1Hz, though measuring via scope it shows the period to be 0.66Hz (1.5sec/cycle exactly). The confusing part is that with these figures, we get a cycle time of ~110 seconds, not 180. Still not super clear how this works.
 At low values it seems to be pretty accurate (eg. 5 sec), but with my test of "180s" (8, 6, 5 and 4 high) yielded approximately 3m18s (almost 200s). Timing the stock setting gets 2m57s, or 177s.

-The DIP switch config for the steady 3 min cycle timer is, from left to right (Up = ON): up, down, up, down, down, up, down, up. This sets pins 1, 3, 6 and 8 high, and 2,4,5,and 7 low (the DIP switch numbers are backwards in reference to the IC pins). This equates to a RC time constant of 165.
