They are available in the following frequencies. The radio identification or frequency range can usually be found on a sticker on the base of the radio. Watch out for the C0 "Band 3" models which are outside of the amateur band. Otherwise almost all the radios you come across will be B1 VHF Models. | They are available in the following frequencies.

+ | ====== Cleaning Tips ====== | ||
+ | |||
+ | A lot of the units you'll purchase will be well used, often ex-Taxi. This can lead to some unsavory buildup of the smoker and dirt kinds which can penetrate into rubbers and leave a residue around the radio. | ||
+ | |||
+ | When cleaning the radio, you might wish to follow the basic notes outlined below: | ||
+ | |||
+ | === Head Unit === | ||
+ | |||
+ | * Remove the head unit by prying gently along the bottom edge between the seal and head unit plastic (page 34 Fig. 2.1 - {{: | ||
+ | |||
+ | * Pull off the volume knob (this will separate easily with a firm pull, and will leave a metal retention spacer either on the spoke or in the knob. Don't lose this!) and release the three clips on the PCB retainer in the head unit (page 134 Fig. 6.4 - {{: | ||
+ | |||
+ | * Remove the button membrane which may contain lots of dirt buildup. Remove the 4 plastic light pipes from the membrane, wipe them clean and set them safely aside. They are keyed in two directions, both which side of the membrane they sit on (square vs round) and orientation (teardrop shape) so you cannot re-insert them wrong without it fighting you. | ||
+ | |||
+ | * Use a flat object such as a screwdriver to peel away and discard the felt sticker in the front plastic covering the speaker grille. This hides and sticks to dirt buildup which is practically impossible to clean away even using soap and water. This will not affect audio performance. | ||
+ | |||
+ | * Use warm, soapy water and a toothbrush to scrub the speaker grille and inner button holes of the front plastic toroughly, as well as around the rest of the inner plastic. This is safe to submerge. Rinse and ensure dried (a hairdryer on low here can help). | ||
+ | |||
+ | * Use warm, soapy water and a disposable cloth and toothbrush to gently clean the button membrane. Take care to not rub off the symbols, and do not scrub the black pads on the back as these are conductive contacts. This is safe to submerge. Rinse and ensure dried (don't use the hairdryer here, but pat and shake dry and leave to the side for a while). Make sure you did not miss any water in the light pipe holes or between the buttons. You can replace the light pipes once dry. | ||
+ | |||
+ | * Re-insert the membrane, click back in the PCB (make sure the speaker alignment slot is correctly positioned). | ||
+ | |||
+ | |||
+ | === Chassis === | ||
+ | |||
+ | * Remove the outer plastic casing using a flat tool of some kind (page 136 Fig. 6.5 - {{: | ||
+ | |||
+ | * Wipe down the exterior aluminium body using an anti-bac wipe, do not scrub or spray unless caution is taken not to get this in any ports. Don't worry about the lip between the top and bottom halves as this is sealed with an o-ring. | ||
+ | |||
+ | * Wipe between the fins of the rear heatsink. | ||
+ | |||
+ | * Remove the BNC and expansion port (if applicable) rubber gromets and clean these in warm soapy water. | ||
+ | |||
+ | * Gently wipe around the rubber on the power and expansion connector areas. These might need an anti-bac + flathead combo to reach. | ||
+ | |||
+ | * Remove the four screws on the top of the chassis and part the top plate from the radio (page 138 Fig. 6.6 - {{: | ||
+ | |||
+ | * Check if your unit is fitted with an expansion board. If the red expansion connector is visible, the answer is no. If the answer is yes, ask us in the Discord what the board is and whether it is safe to keep. If in doubt, remove the board, as some boards will be detrimental to audio quality and will break Packet. | ||
+ | |||
+ | * Ensure the o-ring is seated correctly and will not be pinched, then replace and screw down the top plate. | ||
+ | |||
+ | === Mic === | ||
+ | |||
+ | * The mic is extremely simple and completely passive electronically, | ||
+ | |||
+ | * Unscrew the PCB and lift it gently, unplugging it from the cable. | ||
+ | |||
+ | * Very gently pull the mic out of the front plastic and set the PCB aside. | ||
+ | |||
+ | * Lift and remove the PTT plastic button and metal spring. Clean the PTT plastic button with an anti-bac. | ||
+ | |||
+ | * Remove and wipe down the rubber seal/button passthrough piece. | ||
+ | |||
+ | * Wipe the outer casings and run an anti-bac along the coiled cable. Make sure to clean the screw holes with an anti-bac and small screwdriver. | ||
+ | |||
+ | * The grille on the front of the radio is 99% for show with only a small hole for the mic itself. You can scrub this gently using a toothbrush and some kind of spray, though make sure you did remove the mic and separate away the PCB in the previous step. An anti-bac probably won't go deep enough. I used 99.9% IPA successfully but this is not advised as it can be harsh, but is very effective at removing grime. | ||
+ | |||
+ | * Reattach the rubber seal, place back in the spring and PTT plastic button, reinstall the PCB (there are wire routing channels for the mic wires), and screw the mic together. | ||
====== Packet Configuration ====== | ====== Packet Configuration ====== | ||

+ | That may not be possible for all radios, in which case use the Read Radio button to put the programming software into a state where the radio will take what the software is set to, and modify it as required. | ||
