MFJ 815 B Cross Needle Peak Reading HF Wattmeter:

The MFJ-815B cross-needle meter allows you to monitor both
forward and reflected power, and SWR simultaneously. There
are buttons to select either Peak or Average reading and
power ranges of 200/2000 watts forward and 50/500 watts
reflected. Frequency coverage is 1.8 to 60 MHz, so it covers
6 meters in addition to the HF bands, making it ideal for
some of the new rigs that include 6 meters.
The peak reading function of this meter and meter light
require external 12 V DC.

This particular unit works fine, and looks very close to new.
With paper work for $65.


MFJ 1272 BX switch to transfer between microphone and TNC:

MFJ made these so it would be easy to use a TNC such as the AEA 
PK-232.  The small box has a socket to plug your microphone into on 
the front, along with a switch to switch between mic or TNC.  There 
are two cables coming out of the back, with one going to the mic jack 
on your rig, and other going to your TNC.  There is also provisions 
for receive audio in, and an external speaker. No power is required. 
Inside the box is a series of jumpers, so that it can be configured 
for any rig.  Paper work is included that shows how to set the jumpers 
for most of the common rigs (Kenwood, Yaesu, Icom, Alinco, etc.).

MFJ 1272 BX - Designed for the round 8 pin microphone connector
and the AEA PK-232

It works fine and looks close to new.  $30

receiver. Get one of these, and leave the noise behind.
