Thanks to all those who replied with information and thanks Hans for the datasheet. I bit the bullet and ordered one today and will report on its suitability in due course. A quick report on my Ult.

Thanks to Tony (BZB) and Dick (BBH) for their thoughts. I'm confident I'm not overloading the receiver, I've made it as deaf as possible and the QRSS TX is well terminated. The signal the RX is

This one works very well with the v1.04 firmware. It wouldn't work at all with the v1 and 2. The thing that most recommends it to me is that the same GPS engine is on sale at nearly three times the

David makes a good point. A lot of the old school GPS units require an external active antenna which need to be sited in direct view of the sky. Newer ones have built in antennas and usually are very

Probably overkill for the project but this GPS board is a useful tool for experimentation though the price is up dramatically since I acquired mine. It does (mine did) come with all the goodies.

Hi folks, Had taken a gamble and purchased the low voltage version GPS16-LVS on ebay for ?15ish from Hong Kong. Arrived in UK after about 7 days. When I get the time to interface with the kit I will

The input voltage is "8 to 40 Vdc unregulated", so it will require a separate DC voltage supply. Sverre LA3ZA, http://la3za.blogspot.no/

Bob Ok, I couldn't resist googling for the datasheet. See http://www8.garmin.com/manuals/GPS16HVS_TechnicalSpecifications.pdf . It does appear to say on page 7, that you would by default see a 100ms

It is very common on WSPR to see a double decode several db down on a very strong signal. It is particularly likely when you are swamping your own receiving system with a local mept like this. It

Hi Bob On the face of it, it looks potentially suitable, because it does claim to have a 1pps output and a serial output supporting NMEA-0183 and the required $GPRMC sentence. The question I would

It may be related to the sound card but that would also show up on off air signals from other stations, particularly on strong signals. I have found that sometimes 100Hz sidebands may be produced if

I am looking for a GPS unit to use with the Ultimate MEPT, would this one be

: What frequency band is "medfer" ? Generally considered the US AM broadcast band, some 530 - 1710 KHz. Due to antenna and efficiency limitations, most MedFER (Medium Frequency Experimental Radio)

Thanks Stephen. Since last post, WSPR now up and running (across the shack). QRSS into dummy load and RX made deaf. No padding to call sign field was needed, only 5 characters G8OQW entered. WSPR

David, I believe that Hans put that there because some people found the original cursor a bit difficult when inputting parameters. So that gives you a choice. Thanks for the feedback, it really is

Hi Stephen, V1.04 upgrade received and installed all OK. Many thanks. Worked first time with my GPS, frequency, locator and time all correctly updated. There seems to be an additional Menu setting

Guys, I made a mistake in the slip telling you about the 160 meter output filter. C5 and C8 should be 820pF and C6 and C7 should be 2.2nF. So if you have made up the kit please swap C6 and C8 and all

Thanks for the info Philip, sorry for the extra L in the last post ;) 73 Colin

Colin There isn't much activity at the moment on 160 but Chris on this link operates a 160 grabber quite often and being the nice guy he is, will set up his grabber if you contact

Colin, Thanks for the note. To answer your questions in reverse order :- I plan to do another 200 kits and have all the parts apart from some of the processors, which i used to recover from the
