1. Built and tested receiver PCB from "Better Ears for the MAVTI-40" see QST
article in October 1985 pg.14, or QRP Classics pg.140.
The receiver is built on a gold plated (2 sided) PCB about 5"W x 3 1/2"W.
It contains all the circuits of Fig. 6. The audio band pass has been opti-
mized for a 600Hz center frequency. Although a 40M double tuned band pass
filter is installed, this can easily be changed for the receiver to operate
on any band. The PCB also includes T/R keying and antenna change over. Just
add a VFO for a fully functional receiver. I recommend the NG1G premixed
VFO (see QRP Quarterly) since the VFO buffer to drive the SBL-1 is on the
PCB and this would allow you to build for any band. Add a transmitter and
sidetone and you can build a complete transceiver around this module. One
notable feature of this reciver circuit is the notch filter which works
quite well. Price does not include the few components that are chassis
mounted (e.g. jacks, pots etc.). Full documentaion included. Price $50.00
4. SWR/Power Meters - These meters are new, clear plastic with a black band
at the bottom. SWR is indicated at 1:1, 1.5:1, 2:1, 3:1 and by a red arc
for > 3:1. Power scalers are 0 - 10, 0 -100 and 0 - 1000. Size is 2 7/16"W
x 2 5/16"H. The mounting hole is 1 3/4" diameter. The movement is 100uA.
Price is $10 each.
Shipping is not included in any of the above prices.
