Re: Activity Monday Night

Peter <pete-ebs@...>
 

I'd like to point out that ASCII NMEA messages were only linked to 4800Bd by
a certain number of equip manufacturers as they were operating in the
sailing/autohelm and auto-bridge businesses.
Largely for 'weekend sailors'. E.g. NMEA 1v0-1v5. thereafter it wasn't
fixed.



Professionally, running at 4800 was a pain as it was a bottle neck, many
other data rates were used as standards by Trimble, Ashtech, etc.
'The faster the better' as one got more time to crunch numbers instead of
just reading them in. 9600Bd was much used in the 1990s proceeding to
115200 in the 2010s.

Sometimes one can get serial ports to go even faster to 230400Bd, or just
maybe have to drop down to 57600Bd



See here:-


2 400

the modem speed that every machine came with after 9600 was available...


4 800

!!


9 600

"at last, fast enough!"


14 400

but then came...


19 200

2 x 9 600


28 800

fastest base signal rate on a phone line


38 400

4 x 9 600, popular RS-232 and modem speed


56 000

6 x 9 600, popular modem speed


57 600

popular RS-232 speed


115 200

4 x 28 800



A simplistic viewpoint but valid.

Yes, you're right. the @@Ea command was for setting up its own binary
protocol message type.



I've searched back in the archives and found one listing that included
commands to set a Motorola GPS to send NMEA, as part of its setup. Note
the change of baud rate part way through as its native binary ran at 9600
baud, but NMEA standard is (was) 4800 baud



The Code is copied below.



So you are part correct in your setting, but you then need to issue the
command to tell it what NMEA sentences to send, and how often.

Hi John

I hope you (or anyone else for that matter) find some of it useful.

I write my software for my own amusement but sometimes I feel others may find it useful. That's why
I uploaded it. It appears that the one called GPS Utility doesn't work properly in Poland (honest!).
Never worked that one out. But then I'm the first to acknowledge that I'm not great at this stuff.

As they say in south Wales "I'm just a potcher".

Cheers

Hi-Res Locators

Andy G4JNT
 

Looking at activity lists, I see people now seem to be adopting 10 character locators for a resolution in the order of 18 metres.

There was a bit of discussion about these  a while ago, including at IARU, and I believe the standard for the final two letters was the 24 sub-square version, using letters A to X in the same way as for characters 5 and 6.  This means the final squaroid has dimension of 1/96 minutes of latitude and 1/48 minutes of longitude.

If anyone using these ever finds a final pair including the letter Y, this will mean the software has used the 'other' form with a 25 division squaroid, for 1/100 and 1/50 minutes.  The positional error is, to all intents and purposes, irrelevant but it is Wrong.   Can anyone discovering this make known the software (or "App" in modern-speak) so we know what to take care with

My just-completed new 10GHz PortaBeacon automatically generates this 10 digit locator (24 subsquaroid version)  and incorporates it into the message sent during the odd minute. The latest version of GPS_Locator_Display uses the same format I tested the new PortaBeacon control software for the first time today, driving out to a couple of spots and receiving back home (on a slotted waveguide antenna at the end of 10 metres of LDF-450 ).  
On returning to look at the WSJT decode screen, it duly told me where I'd stopped

Hi Andy was just about to suggest bringing the mini beacon out when I was about to reply to the GPS message. I'm sure it will generate quite a bit of interest as it did on its last outing. As to the Motorola GPS it was a freebie so will keep trying to get it to switch to NMEA can talk to it but just won't switch the command is @@Ci as far as I can tell. Anyway as you say it's old hat and there are may alternatives around even with programmable o/p from a few Hz to MHz so may upgrade one day.

To add a bit of "something different" I have my new portable mini-beacon on 10368.35MHz that I can take out to a spot - possibly Lane End as well as its one of the few decent sites around here.

JT4G message ONLY; just a few seconds of carrier and no dinosaur.   100mW to a 20dB horn so I'll need to know where to point it - Quantocks / Devon Dorset presumably.   Mob phone 07576 765856

Hi all just been speaking to Adrian G4UVZ who is going to go portable tomorrow from IO81LB06 and now Ed G3VPF will be at IO80QQ42. I will be at Lane end IO91JA37 we hope to be up and running between 6:30 to 7:00pm I will have to be gone by 9:00pm due to early start in the morning. So hopefully we can work a few of you all being well.

Re: New Version of GPS Locator Display (GPLOCDIS) PIC Firmware

Hi John

NO, I gave up on Motorola Oncore support after getting rid of the last module that generated it.   So even if I wanted to write the code now, wouldn't be in a position to test.     IIRC, the Motorola modules could all be switched to generate NMEA with a command something like @@Ea[something] 

There are now so many really low cost and good tiny postage stamp GPS modules around, all delivering NMEA by default, its really not worth trying to press old ones with obscure data formats into use.

Three of the Bell Hill beacons use Mot binary data for their WSJT engines as the code was written back when it was commonplace ;  the two later ones, 24GHz and 5.76GHz needed NMEA as I could no longer do Mot Bin when they were upgraded.  So installed a second Garmin GPS on site for those two.    If 'SCS, SCF and SCX are upgraded, they will have to use that as well

Thanks Andy don't suppose you have a version to read Motorola Binary ? as I just can't get mine to output NMEA, been using WinOncore to read the data at the moment.

There appears to have been quite a few users of this bit of PIC code that takes the NMEA data from a  GPS and uses this to calculate and display the LOCator,  Lat / Long, Date +_Time plus SOG and COG data contained in the message on a two or four line  LCD

The latest version of this code now includes a new Locator calculation algorithm that shows the 10 digit LOC, accurate to about 18m at mid latitudes.   It also has compile time flags for NMEA baud rate, since the latest generation of GPS modules tend to now use 9600 baud; also the option of  km/hour or miles/hour (there no room to show both).  The display appears on a 20 char x 4 line LCD.

Full details in http://www.g4jnt.com/GPLOCDIS.ZIP  which still includes  the earlier versions for backwards compatibility.    In view of the use of compile time flags this latest version is supplied as .ASM file only - you will need to assemble into a .HEX .

(The high-res locator calculation routine was developed initially to go in my 10GHz portable beacon project, allowing the transmitted Locator to be correct anywhere without having to reprogramme the controller PIC contents every time its location is changed).

Acttivity list for the UK Microwave Group mm-wave contest Sunday 17th July

John Quarmby
 

I will not have access to email other than via a phone for the next few days, so I won't be able to collate an activity list for this event, however I encourage participants to advertise their plans here on the reflector to maximise activity.

73 & good luck to all
