On another list it was mentioned that they use the 10 MHz band for control purposes. They apparently are using a Small Wonder Labs QRP transceiver and the onboard microcomputer decodes CW commands. 73 Trevor M5AKA

muTek GNLA432e info
by Ab4ab＠aol.com 28 Mar '12

28 Mar '12

Hello, Some time ago I found a muTek GLNA432e at eBay. It was inadvertently advertised as a 144 MHz unit and was also supplied with a SBLA144e schematic. So I'm at a loss how to troubleshoot this nonworking unit. I have searched the net but found nothing useful. If anyone knows anything about this unit, e.g., transistor used or even better the schematic, please let me know. It is a vintage well built 1983 unit with RF sense switching so I really would like to get it up and running. Thanks Ben AB4AB

Transatlantic balloon attempt
by Bob Bruninga 27 Mar '12

27 Mar '12

I still have not heard of anyone copying the HF beacons on 30 and 40m. (10.147 and 7.102 MHz). I am curiouis about this because our next balloon flight will only have an HF beacon and nothing else. I have been in the 400 mile footprint most of the morning, and have heard nothing, though it is tracking out past Nova Scotia just fine on APRS... http://aprs.fi/KD2AUC-1 Bob, WB4APR ---- Original message ---- >Date: Sat, 24 Mar 2012 17:48:18 -0000 >From: aprsisce(a)yahoogroups.com (on behalf of "Steve Daniels" <steve(a)daniels270.eclipse.co.uk>) >Subject: RE: [aprsisce] Transatlantic balloon attempt >To: <aprsisce(a)yahoogroups.com> > > For those interested tracker battery volts are > showing as 9.21V.
