Mike ¨C ? Sounds like you are on the right track, just make sure you are running KPG-29D on a computer running DOS (No Windoze).? Correct factory cable is a KPG-4 which has a 25 pin serial connection on one in and a 6 pin connector on the other end to plug into the microphone jack.? Been a while since I programmed one but it seems like you can select a limited number of com ports in the software for the programming cable. No special buttons to hold down, the radio should indicate ¡°program¡± when you plug the cable into the microphone jack IIRC. ? Andy / NC4AB ?

Subject: [repeater-builder] Kenwood TK-760H VHF ? We have a Kenwood TK-760H VHF that needs to be reprogrammed. I have the correct software KG-29D and just got what I believe is the correct Serial Port programming cable however I cannot read the radio. I¡¯ve looked at the RB website and found the manual for the radio but no other information on programming other than the software to use. Is there anyone in the group that could shed some light on what the problem could be. Thanks Mike W1ZFB

NHRC PXP ,,i need a PIC or the file !!!
Hi all
i hope your are all ok ,
i need a new PIC for my Ge Phoenix programmer from NHRC PXP.
On their web site they are saying they dont respond much to consumer service,
maybe there is a gentleman here that can help me,i need another PIC or a copy of the file so i could ask a friend to burn me a new PIC,,mine is dead because of a ground loop i add!
can someone help me !
i need that programmer
you can answer me direct at ve2ckn2 at hotmail.fr
thanks guys for the help and

OT: Sea-Pac 2021 Cancelled
From the SEA-PAC Executive Committee Chairman
?
The SEA-PAC Executive Committee has been closely monitoring the continuing COVID-19 pandemic situation has determined that the safest course of action for all is to cancel the 2021 in-person event.
?
This decision was based on the uncertainties of more COVID outbreaks, vaccine availability to all, and the probable social distancing requirements.? But most importantly, it is based on our genuine concern for the health and safety of you, the attendees, vendors, and presenters.? We firmly believe that providing our Ham Radio community with a safe and quality convention experience is paramount.
?
To offset this cancellation, the SEA-PAC Committee is exploring alternate online and on-air activities to engage our loyal attendees during 2021.? Watch for future SEA-PAC Wave newsletters with the details as they become available.
?
Finally, we look forward to hosting you again in Seaside, Oregon, on June 3rd, 4th and 5th, 2022. Thank you for your patience and understanding and we invite you to start planning for SEA-PAC 2022.
?
73,

Re: Regulator - 12vdc to 5vdc for Raspberry Pi
Jim,
These are similar to what we have "upgraded" to for our MTR2k board. Ours do not have the voltmeter integrated. We also swap the variable device for a fixed 5v one.

Re: Regulator - 12vdc to 5vdc for Raspberry Pi
Just as an FYI to all: Scott has had really good luck in sourcing his... Yes and no. We also had some "bad" ones sneak into the pool. Since we got burned (literally) a few times, we are now carefully testing each batch we get and reworking them as necessary. (changing parts values to those recommenced by the data sheets.) Since we have started doing the rework and test, we have had ZERO failures that we know about.

Aside from the suggested supplies that others have given you might want to try one of these.
I've used early models of this:? ?on a dozen remote sites.?? The current models accept 5.5-24v or 5.5-32v depending on model and also provide additional useful features.
I'm in the process of qualifiying this UPS:? ? It will power any of the RPi? models and is usable with an input of 5.5-18v (suitable for use with Solar panels)

Re: Regulator - 12vdc to 5vdc for Raspberry Pi
Hi David, About 30min before I read Kevin's text, I purchased two "Car Powered Technologies" units for $13. See pic. The other ads clearly showed just the letters CPT on the label. Unfortunately, I didn't make the connection it was the same outfit. So hopefully they're not potted, and I'll crack one open and see if there's a way to stick a heatsink on the chip. I'll keep you posted. I likewise will use it on a Pi3 with Hamvoip Allstar. Presently using the wart that came with the Pi, but want all my repeater power except fan to be 13.8vdc. Frank N6CES

Hi Frank,
I've found that the "CPT" power supplies are not all created equal. It
would seem the manufacturers figure since it's hidden in potted epoxy, no
one can see what was actually used!!!
Early "CPT" power supplies that I purchased worked GREAT! And, I
recommended them for HamVoIP RPi2/3 users (this pre-dated the RPi4). Then,
I got some more batches of these supplies that they were junk--they ALL
failed, in time.? Grrrr.
I dug one of these older "CPT" units open one afternoon, and found this
exact board hidden inside:
Here is the converter chip datasheet:
Anyhow, my reasoning for avoiding the "CPT" modules is that you can't tell
what you're actually getting, which is disappointing, because the potted
converter modules have a very nice form factor.
