January 2007 QST Feedback

  • The voice telephone number of ACOM International is 508-533-7765. There was a typographical error in the phone number listed at the end of the Product Review of the ACOM 1010 HF Linear Amplifier [Dec 2006, p 59].

  • In the In "The MicroR2--An Easy to Build 'Single Signal' SSB Receiver" [Oct 2006, pp 28-32], Note C in Table 2 has part numbers C31 and C32 interchanged. C30 and C32 should be 0.1 µF and C31, C33 and the two inductors are eliminated in the "low hum" version as discussed in the text and shown in Figure 5.

  • The Short Takes review, "A 30 and 80 Meter Module for the Elecraft KX1 CW Transceiver [Nov 2006, p 63], indicated that the Canadian time/frequency radio station transmits full-carrier LSB on 3.330 MHz, 7.335 MHz and 14.670 MHz. John Wilson, KK6KU, points out that CHU transmits full-carrier USB on those frequencies. That means that the KX1 can be used to receive CHU only on the two higher frequencies. The KXB3080 module enables CW and LSB reception in the range from 1.000 MHz through 5.505 MHz when the KX1 is switched to the 80 m/75 m band. USB reception is available on the KX1 only between 5.000 MHz and 16.505 MHz. -- Bruce Prior, N7RR
