Mutek Preamps
by howard dawson 16 Jun '10

16 Jun '10

Hi All. I am looking for any Information on 2 Mutek Preamplifiers I have, One is for 2Mtr operation type GFBA144e and One for 70cms type GLNA 432e. The 2mtr one has a 4pin female connector on the front labeled "CTRL" and 2 "N" type antenna sockets marked "Ant and Tcvr". The 70cms one has a 3pin male socket also labeled "CTRL" and the same "N" type sockets. Any information regarding where I might purchase these connectors and any other Info would be very much appreciated. I have emailed Mutek a number of times over the last 2 months but no response from them to date, their Web site also seems to be a little out dated. Many thanks in advance. Howard. G0VBT Amsat UK

The Southern hemisphere is a fairly large area, please be more specific. The statement you made creates doubt about our operating habits implying that we are irresponsible operators. AO-51 is not in eclipse whilst it in range of Southern Africa. This is based on the information as given by SatPC32. Greetings. 73, Pierre ZS6BB

Mike - Contact Scott Malcom, KA7MEF Technician and Lead Go'fer at MTS Repair. Scott worked for Icom Service, when this radio was new, and should be able to provide the necessary insight for your work. He also has access to some parts from junked/donor radios of that classic Icom era.

It seems as if the heat sink is trapped between the N connector barrel and the PA circuit board. Unless the connector barrel pulls off of the pin, I see no way of removing it, or the circuit board to get at the pin. I don't want to use to much force in pulling off the barrel. Perhaps heating the pin might release the barrel. Any suggestions? Should I send it to Icom and let them worry about it? ____________________________________________________________

Re: CP antenna from 2 WiFi panels

Antenna arrived today. Shipping was $9.30 so total of $24.29. All white plastic encapsulated: 4.5x4.5x1.0 inch and has four mounting holes on the flange. I will mount it on a 1/8-inch thick aluminum plate attached to my satellite elevation crossboom using U-bolts. Very nice looking workmanship. 8 dBi gain translates loosely to 6 dBd ( about the free-space gain of a 3-element yagi. 73, Ed - KL7UW At 06:58 AM 6/9/2010, John Belstner wrote: >Good price Ed.
