[time-nuts] GPS down converter question

I am looking at building a GPS down converter. LO 1500 Mhz locked to a 10 MHz ref. The IF will be at 75.42 Mhz how wide should it be? My question is simple. What should the IF pass band bandwidth be? Not sure if it should be 3-4 Mhz, 10 or 15 wide. Thanks Paul WB8TSL

Re: [time-nuts] Loran C returning to a station near you...

OK LORAN is on the air up in Boston. I had just turned off various equipment this morning. So starting it back up after testing it yesterday. Lots of large static crashes. Regards Paul WB8TSL On Sat, Jul 18, 2015 at 7:04 AM, billriches bill.ric...@verizon.net wrote: FYI Wildwood eLoran

station is sending the master and secondary delayed emission. Its simply not the same ole sound. But it still works very well for checking frequency. Regards Paul WB8TSL On Sat, Jul 18, 2015 at 12:52 PM, billriches bill.ric...@verizon.net wrote: Correction on times for Mon - thurs - start 900 edst

because of the large signal bandwidth +- 10Khz. With the whip on winter nights I do get occasional lock of the European signals. Granted this will be an over the summer project.

John I don't know if there was. But the timing receivers like the Austrons and SRS could really derive very accurate frequencies especially if you lived 60 miles from the transmitter. :-) Regards Paul. WB8TSL On Wed, Jul 15, 2015 at 4:23 AM, John C. Westmoreland, P.E. j

Poul-Henning, The reason to stay with the LORAN C style pulses is very very simple. It allows our time-nuts Austrons and SRS to work. Its the only way I get any of my tax dollars back. :-) The good news is no official government person reads time-nuts. Regards Paul On Tue, Jul 14, 2015 at 12:16

Re: [time-nuts] Any other useful purpose for Austron 2100F or SRS FS700 receivers in US

Magnus I use a 420 ohm resistor to make FS700 happy. I have a LORAN C whip antenna and preamp that then feeds a distribution amplifier for the 4 Loran C rcvrs. The loran C simulator lives in the same box and can feed the rcvrs also. Regards Paul WB8TSL On Sun, Jul 12, 2015 at 11:10 AM, Magnus
