Qīngtíng (Dragonfly) RadioThe Dragonfly or Quintíng is our first attempt at using transistor technology into our military radios and developing an integrated radio jammer.
First, we have developed an standard transistor radio, reducing both the weight and fragility of our radio devices, enabling greater availability of space in our vehicles (which can be used to carry more ammo) and giving our radio operators more free space on their backpacks.
Secondly, we have designed a set of two transmitters for the radio. These two transmitters emit continuously a prerecorded piece or static. However, instead of doing it in a fixed frequency, they each rapidly travel along an assigned half of the AM spectrum, needing as much as a quarter of a second to get across one side to the other of their assigned area, effectively jamming communication in the area at the press of a button.
As our next priority and probably the most difficult step in our development process, we have left a slim channel for communication for our troops. This small channel is the space the two transmitters leave between their respective bouncing ranges. The “bouncing range” of both transmitters abruptly adjusts every 5 seconds, moving the clean channel to the left or the right of the spectrum.
From this we have devised three modes of operation for the radio in order to allow communication and jamming at the same time. A “Manual” (only useful when there are no jamming involved) , “Automatic” and “Standby” modes.
The “Automatic” mode allows the user to enter a waterproofed punctured cardboard in the machine. The cardboard´s holes change the frequency at which the radio is transmitting or receiving automatically, at five seconds intervals. Each cardboard is useful for fifteen minutes, at which point the machine reads it backwards and repeats the cycle. That means, you cannot enter the “clean” channel for a spam of fifteen minutes (because that way you would jamming other radio comms and they would be jamming you), at which point you can put the cardboard backwards or forwards depending of it is o´clock (normal), quarter past (backward), half past (normal) and quarter to (backwards). In "Standby" the cardboard goes through each hole on a five second spam without the radio being activated, allowing it to be activated and instantly start transmitting without waiting for the next window of opportunity, but consuming less than if the radio was fully activated. The cardboards are meant to be replaced daily and are marked by a character in order to facilitate identification.
Finally, we will design two additional sets of transmitters, jamming at the FM and HF ranges, without leaving the slim communication channel. They could be linked in the same manner as the first to the radio, by cables. These two sets won´t be deployed until two turn from now on, hoping they try to work around that by making an FM and effectively making they waste a design turn.
This should allow us to deploy two variants of the radio, assuming we got all the design objectives (save for the extra two sets). A Clipped variant, which has no transmitters and is intended for field usage by our troops and front line vehicles, and a Winged one, meant to be mainly carried by unarmed Inmortals, ground vehicles (Qui-Chu, and Piāoqiè guānsī where some combat is expected) and which has an extended antenna in order to improve its range. It can be also deployed by soldiers in fixed emplacements, The disassembled full equipment of the Winged variant can be carried by three soldiers, although field recommendations recommend distributing equipment between five men in order to allow soldiers to carry other field equipment. Assembling time is roughly 15 minutes and the impromptu station is covered by a camouflage net in order to make it less detectable for enemy helicopters.
Loudspeakers can be fitted to the radio in order for the platoons to enjoy the virtues of Toskeshian and Western opera.
Selected prerecorded pieces, which can be easily substituted in the field, include:

Same arguments as last time. Would impair the ability to make meaningful pushed into our territory, nullifying their artillery and naval support advantage.
