Product no.: KSYN3AUPG

ATTENTION: Due to the high number of orders, our stock is empty. New KSYN3A will be available again early in April 2015

KSYN3A Synthesizer Upgrade Kit for K3, KRX3 (Note: Synthesizers used for the K3 and the KRX3 must both be the same model. K3's with the KRX3 will need to upgrade both (2 total) synthesizers to the KSYN3A.)

The KSYN3A is included on all new K3s shipped starting 1/23/2015, s/n 8801 and later.

The KSYN3A synthesizer module is a completely new design that improves on the original KSYN3 in several ways:

ULTRA-LOW PHASE NOISE The KSYN3A significantly improves the K3's already excellent RX and TX phase noise at close carrier spacings. This in turn noticeably improves the K3's top performing close spaced Rx dynamic range, yielding even better weak signal detection in the presence of strong signals.


EXCELLENT MECHANICAL STABILITY The KSYN3A is virtually immune to both physical vibration and magnetic coupling, and operates over a very wide temperature range.

600-METER COVERAGE The KSYN3A extends VFO tuning down to 100 kHz, with sensitivity gradually falling off below 450 kHz. Transmit output is as high as 1.0 mW for use with a suitable external amplifier. (Note: 600-m and below operation also requires the KBPF3 and KXV3 options.)
