Heathkit RX-1 Mohawk Ham Receiver

Styled to match the "Apache" transmitter the "Mohawk" ham band receiver provides all the functions
required for clear, rock-steady reception. Designed especially for ham band operation this 15-tube
receiver features double conversion with IF's at 1682 kc and 50 kc and covers all the amateur
frequencies from 160 through 10 meters on 7 bands with an extra band calibrated to cover 6 and 2
meters using a converter.  Specially designed for single sideband reception with crystal
controlled oscillators for upper and lower sideband selection. A completely preassembled wired
and aligned front end coil bandswitch assembly assures ease of construction and top performance
of the finished unit. Other features include 5 selectivity positions from 5 kc to 500 CPS, bridge
T-notch filter for excellent heterodyne rejection, and a built-in 100 kc crystal calibrator. The
set provides a 10 db signal-to-noise ratio at less than I microvolt input. Each ham band is
separately calibrated on a rotating slide rule dial to provide clear frequency settings with more
than ample bandspread. Front panel features S-meter, separate RF, IF and AF gain controls, T-notch
tuning, T-notch depth, ANL, AVC, BFO, Bandswitch tuning, antenna trimmer, calibrate set, calibrate
on, CW-SSB-AM, rcceivc-standby, upper-lower sideband, selectivity, phone jack and illuminated gear
driven vernier slide rule tuning dial. Attractively styled with die-cast aluminum control knobs and
escutcheons. No external alignment equipment is required for precise calibration of the "Mohawk".
All adjustments are easily accomplished using the unique method described in the manual. An
outstanding buy in a communications receiver.
