Chipswitch
Features

30 MEMORY CHANNELS WITH TEMPORARY CHANNEL LOCKOUT AND REPEATER OFFSETS

The original HR2510 / HR2600 / LINCOLN has basically one memory available to it in the sense that it remembers the frequency you were last on during a power interruption. The CHIPSWITCH supplies you with three groups of MEMORY BANDS. There are now ten (10) user programmable frequency channels available for each MEMORY BAND. You can elect to have repeater offsets to any of the stored memory channels. You are also provided with the ability to lockout any memory channel(s) temporarily during SCAN/SEEK functions.

EXTENDED FREQUENCY COVERAGE
Adding the CHIPSWITCH  IC will allow the radio to operate contiguously from 11 through 10 meters without any further modifications.   Installation instructions are available for review.
 

With additional modifications to the PLL PCB,  the CHIPSWITCH allows full contiguous coverage from 24.800 to 29.999 MHz. (12 through 10 Meters).   Modifying these radios for use in the 12 Meter range can be done at a few sites.   Although with the Chipswitch, these radios could be operable to 15 Meters, some spurs near 15 Meters cannot be adjusted out, therefore a  password has been added to the Chipswitch program to disallow access beyond 12 Meters at this time.

PROGRAMMABLE SCAN/SEEK FUNCTION

The original HR2510/HR2600/LINCOLN allows you to scan on an arbitrary 'band basis." This new feature allows you to select a range of frequencies for SCAN and SEEK while in band 0, or SCAN/SEEK by memory channels in band 1, 2 and 3. The SCAN feature allows you to set the 'hold-time' (the amount of time the radio waits to resume its scan function after that particular frequency quiets down). The SEEK feature is identical to the SCAN except for when the radio is scanning and detects activity on a frequency, the radio will receive on that particular frequency for a user-programmed length of time before it continues the scan. SCAN and SEEK are completely user programmable for 5 or 10 kHz steps in band 0.

PROGRAMMABLE CHANNEL UP/DN BUTTONS

This provides you with the ability to program the radio's channel up and channel down buttons to change channels/frequencies in any of five (5) different ways. (5 kHz, 10 kHz, Underlined digit, etc.

PROGRAMMABLE MICROPHONE CHANNEL UP/DN BUTTONS

This provides you with the ability to program the microphone channel up and down buttons to change channels/frequencies in any on of eight (8) different ways.

SPLIT FREQUENCY OPERATION

When enabled, this allows you to transmit on one frequency, and receive on another.

PROGRAMMABLE TRANSMITTER TIMEOUT

This feature provides the radio with a built-in QSO timer. When enabled, it triggers a programmable timer the moment the radio starts transmitting. When the user-programmed length has been achieved, the radio will stop transmitting. To continue transmitting, just release and press the microphone PTT (Push To Talk) Button.

PROGRAMMABLE TRANSMIT FREQUENCY RANGE

This provides you with the ability to program a range of frequencies to operationally transmit on. In this mode of operation, you still have the ability to receive frequencies out of the user-programmed range, but can not transmit on them.

PRIORITY CHANNEL (Requires optional hardware)

Priority channel operations allow you to program any frequency (i.e. home frequency, etc.) and have the HR2510/HR2600/LINCOLN check this frequency while you are on another, at a user-programmed rate. This feature will not function properly without the optional PRIORITY CHANNEL BOARD.

MISCELLANEOUS

The 'SPAN UNDERLINE CURSOR' now has a 'phantom' 4th position (all 3 underline bars) cursor. This enables you to go through the band in 100 kHz increments. This 'phantom' 4th position is indicated by 3 cursors.

The 'SPAN UNDERLINE CURSOR' position and the underlined digit can be moved by pressing both microphone buttons at the same time. (Great for mobile operation)

The button repeat rate is now programmable.

The internal 'button beep' duration is now programmable from 0 to 0.5 seconds.

The 'RPTR' button on the HR2600, when depressed, will transmit the CTCSS tone to open up a repeater station. Repeater offset selection is required when programming memory frequencies.

The HR2510/HR2600/LINCOLN now has two function modes:

OPERATE MODE

This mode is the radio's normal operation mode.

PROGRAM MODE

The front panel controls are used to program information the radio will use during OPERATE MODE (i.e. memory channel frequencies, split channel, scan functions, etc.)

INSTALLATION

As the name CHIPSWITCH implies, the basic modification of the radio is the replacement of the existing UNIDEN microcomputer chip. A person proficient in soldering/desoldering techniques on P.C. boards is qualified. A comprehensive installation manual is provided. No modification to the front panel is required as all the new features are controlled by the existing knob and buttons on the front panel. The optional PRIORITY CHANNEL BOARD and 12 METER MODIFICATION KITS do require modifications to the circuit boards.
