i have posted two documents related to the recall of the OSD. the first describes how to update the firmware on your GPS, so that is not really related, but...
i forgot to add... if you find any confusing wordage in either document, please email me and let me know. i'll make the necessary changes and repost them. they...
Hi Vince, Yes, one of the millisecond time fields is stuck on 325. The other progresses normally at 0.0334 seconds per frame or 0.01667 per field. Yes, I...
Vince, I found the instructions very clear. I modified my unit with the minimum of fuss by following them, and now have a VERY bright led!!! Regards, Jonathan....
Tony, i checked my records and found that you only have one OSD, correct? a kit you made. one of the first, serial number 004!! i seem to remember this issue...
Hello occultation_observation, That's an unusual name. What do your friends call you? :-) ... You would have had to press the reset button to receive the...
... Tony, this is the first time I have heard of this kind of fault. To have one of the millisecond timers "stuck" would involve a partial failure in the...
Hi Vince and Jonathan, ... Agreed! My only difficulty was that Vince said to use a soldering pencil. My soldering crayon isn't that fine and I couldn't easily...
About a 18 months back, I think it was Bob Sandy (Hi Bob) and maybe someone else, had problems with their Garmin18LVCs and it had to go back to Vince to have...
... Many thanks for your experiment Dave, and reminding me of this extra issue, that applies to "anyone" using a GPS and regardless of what Video Time Inserter...
Hello All, does anybody know about the technical difference between the newer Garmin GPS 18x LVC and the older version without the "x"? Reading the pdf-manuals...
Hi Gerhard, ... As I understand it, the "X" has a more sensitive RF front end. However greater sensitivity is not always an advantage, because it can also...
Hi Geoff, thank you for the information. Now looking again in both data sheets, I see (page #5) that the serial output levels seem to have no difference. But...
in my humble opinion, Geoff is (as usual), correct in stating that it probably doesn't make much difference whether you have a 18 or an 18x. i use an 18x when...
i just did a quick test using the 18x i test with against WWV. i did not notice any leap second issues; the start of the minute coincided with the minute tone...
the OSD has a "poly-fuse" that protects the GPS from excessive current. we chose a 100ma value since the eariler GPSs were, as stated by Gerhard around 60ma....
... I agree Gerhard, that the data sheet shows no difference (between 18 and 18X) regarding the electrical nature of the serial output of the Garmin 18 series....
Vince, I agree, the polyfuse with In=100mA is far away from the point to actuate. A normal poly-fuse will reach this point at about the double current value ...
Hi Geoff, My KIWI is used at the college observatory and I have not been able to check it out since I got your message. I can share a few responses to your ...
Hi Vince, Yes, I bought one of the very first OSDs! I even did a modification of the connectors to have the GPS connector flush-mount on the side of the case,...
... The KIWI OSD pcb has diode protection for reversed voltage, so I wouldn't think that would be a problem. It is more likely a "transient" from an electrical...
Hi Vince, Sorry to be in delay in getting back but I wanted you and everybody else to know that my Kiwi arrived back safe, sound, and better than ever! I...
... No there isn't Gene - the text location coordinates are "set" in the firmware. The only "tweak able" on the pcb, is the "intensity" of the text, which...
in another thread, Geoff points out: "A GPS receiver knows the correct GPS timescale as soon as it has determined a FIX for your location, however it can be up...
... The 15 seconds delta I mentioned, is the difference between GPS atomic time, and the UTC atomic time. Vince you may like to try this with an 18 or 18x...
Hello All It's my first post on the forum This morning I've tested a GPS Garmin 18 LVC The first display was the yesterday date let 260109 and 21h....... As...
... Bonjour Thomas - it is an honour to have you post on the forum. If my memory serves me correctly - it was Thomas that many years ago built the first Video...
I tested mine during the Partial Solar Eclipse here in Manila last January 26, 2009. Yes, at first it was 1 second faster then after 20 minutes i turned off...
