Introduction
The Elecraft XV Series high-performance transverters may be used with
any transceiver or transmitter/receiver pair that covers the 10 meter band.
Separate transverters are offered for the following bands:
 Model XV50: 50 to 52 MHz
 Model XV144: 144 to 146 MHz
 Model XV222: 222 to 224 MHz
 Model XV432: 432 to 436 MHz
Features
I.F. connections to the transceiver can be either single-port, using a single
RF cable, or dual port, using separate receive and transmit cables.
The transverters include an adjustable input level control that will provide
full output from the transverter with I.F. power levels as low as 0.01
milliwatts up to 8 watts. Full protection against accidental high-power
transmit of up to 100 watts into the I.F. port is also included.
The receiver features a very low noise figure with a PHEMT RF stage for
weak-signal work. Relays are used for transmit/receive switching to
avoid receive performance degradation by diode switches in the signal
path.
The transverters are housed in attractive, low-profile enclosures that may
be stacked for multi-band operation. An illuminated band label identifies
the transverter in use. Several transverters may be connected to a single
transceiver. Internal relays select only the transverter for the band in use,
avoiding the need to switch I.F. cables.
Using an Elecraft K2 or K3 as the I.F. Transceiver
While the transverters will work with nearly any HF transceiver, using
them with our Elecraft K2 or K3 offers additional benefits. These high-
performance transceivers provide:
 Low noise, single-conversion, wide dynamic range receiver.
 Single conversion to a low I.F. with roofing filters as narrow as
200 Hz
 K2, 6 transverter bands. K3, 9 transverter bands
 Direct display of the transverter operating frequency to 10 Hz (1
Hz for the k3), including per-band adjustable offsets of +/- 9.99
kHz.
 Low current drain, ideal for Field Day or rover use.
We recommend that K2’s with serial numbers 3445 and below be
equipped with Elecraft-approved modifications that reduce spurious
responses and enhance frequency stability. See Special Notes for Elecraft
K2 Owners on page 4.
