(Everything in Picture)


From the online Manual, 
The Model HW-7 Heathkit Transceiver is a three-band QRP (low power) CW Transceiver with both built-in VFO and crystal transmit provisions. Band coverage is the CW portion of forty, twenty, and fifteen meters. The Transceiver can be operated from the Heathkit Accessory Power Supply Model HWA-7-1, an equivalent low impedence power supply, or batteries. The experienced amateur, QRP man, and novice alike will appreciate the dependability and versatility of this Transceiver.
Whether you use it for standby, camping, emergency operation, or your primary rig, the Transceiver will prove its worth. Band changing and tune-up are easily accomplished with pushbutton band selection and single-control Tuning. The light-weight and compact Transceiver has pushbutton crystal transmit provisions for the novice or QRP roundtables. Main tuning is accomplished through a 6-to-1 vernier that is virtually backlash free. A Relative Powermeter, built-in sidetone, and carry-along size make the Transceiver a pleasure to operate.
