Items supplied with basic repeater:

• Complete radio (We supply) with 25 watt, 220 Mc. Japanese power brick.
• Receiver and Exciter converted and tuned to 220 ham band.
• Crystaled (1 - 5C and 1 - EC ICOM) on your 220 frequency.
• Duplex modifications done.
• Separate receiver antenna port. (Professionally installed in place of lock on front panel)
• NHRC internal Vol/Sq pots supplied and installed.
• Heavy DC Power Cord supplied (4 foot length)


Items not supplied with basic repeater but are available as options:
 

• PLL exciter models with true FM Modulator available for additional charge.  The PLL GE Mastr II *does* require a crystal as the exciter is Phase Locked to the crystal, however it is not synthesized. (Great for flat audio throughput.)
• Micor Squelch option.  (Add a Micor noise squelch to the Mastr II)
• PL, Channel Guard aka CTCSS available extra.  (Can be configured for encode, decode or both.)
• Control Head Connector and Cable available extra. (*May not be necessary anyway depending on controller*)
• Preamp  (Many models available extra.)
• Controller.  (Many models available extra.)

The repeater will require a 20 amp Linear Power supply or equivalent just to run the repeater.  If an add on RF Power Amp is going to be used, please allow for the additional current consumption accordingly.  Astron's are good because of their over-voltage protection.  We don't recommend switching supplies on repeaters.

We use an IFR-1200 A Service Monitor and Cushman CE-15 Spectrum Analyzer in verifying performance on our conversions.  We have the manual on the PLL Mastr II exciter, so we can supply the data on that transmitter.  We choose to use the Japanese power brick for the transmitter PA because it is simply too hard to convert the high-band PA to 220 and have repeatable performance, efficiency, and purity specifications.  The 25 watt brick is rated continuous duty at this power level.
