For this project I’ll be using two pe4302 boards sourced from eBay. They come with the pe4302 chips pre-soldered along with pin header and pulldown resistors.
DuWayne KV4QB, has done a Step Attenuator project and was kind enough to give me a board he had designed when I met up with him at FDIM this year. I’ll use DuWayne’s board and won’t develop my own pcb for this project. I’ll follow his design and possibly make changes at a later date. Here is a link to his blog where you can read in more detail about his attenuator project. http://kv4qb.blogspot.com/
As with DuWayne’s project, I’ll use 2 pe4302 boards connected in series with the control lines in parallel. This will mean that the attenuator steps will be in 1dB increments and not .5dB steps that the pe4302 chip is capable of. Max power input is +24dbm. Total attenuation will be 63dB. There will however be an insertion loss of about 3dB, 1.5dB per board. I’ll likely measure the exact loss and add it in to the selected amount of attenuation so the display will show the actual level of attenuation.
This is just a friendly reminder that tomorrow is our first main meeting for our club year (2019 to 2020)!
It’s also the time when you renew your membership for the club year. As last year, you have the option to renew electronically if you cannot attend tomorrow’s meeting. To do that, fill out the new PARC membership application form (link here) and send it in to me at email@example.com. Once I receive the application form, I will send you an electronic invoice via Square payments. Filling out the form is MANDATORY to complete payment and no electronic invoice will be sent without that form. We are working to automate this further so that all you have to do it “tick the box” to confirm your details and get the invoice electronically in the future.
Baby steps folks, baby steps.
The meeting starts at 8pm at the Fletcher’s Creek Sportsplex in the Youth room.
Business items to note from the PARC Annual General Meeting held on May 7, 2019.
The proposed revisions to the PARC bylaws were voted on by the members and accepted.
The Executive Secretary is now Allen Woolfey VA3IAW and the new Treasurer will be Klaas Westerhof. Thank you to both members for participating in the administration of the club and we look forward to working with you.
Members also voted to allow the sale of the Flex 5000 radio. Anyone interested in purchasing this radio, please contact one of the executive members.
Despite some adverse conditions on Field Day, we still managed to
put in another good showing. Our score of 6348 points earned us the
top Canadian position in the 4A category once again. Overall,
irrespective of the category, we placed second to VE1LD in the
2A category who had 6448 points.
Many thanks go out to all who helped make FD a success.
The RAC S.E.T. is scheduled for Saturday October 13th. from 0730 to 1300 Hrs (Local time), and we need as many volunteers as possible to cover this event. This is a great opportunity for you to test your equipment, and for those members who do not have radios you can check out the Operations at our Trailer which will be set up in the White Spruce Park on Heart Lake Rd (between Bovaird Dr & Sandalwood Pkwy).
The scenario for this Test will be announced on the PARC VHF Repeater on Friday Evening Oct. 12th. between 1900 & 2000 Hrs (Local Time), so please monitor the frequency (146.880 MHz) during that time. Check in time for the S.E.T. will be on Saturday morning from 0730 to 0800 Hrs when you will be given your assignment.
just a friendly reminder that this Sunday is the NVIS event. PARC will be deploying the trailer at White Spruce Park in Brampton. The event will be from 1pm to 6pm local time. For those of you who are not doing their own deployment, but would like to participate, join us at the trailer!
There will be a BBQ, and there will be a charge of $10 for the food. We’ve provisioned for 18 people, and based on the provision $10 will give each person 1 hamburger, 1 beef hotdog or polish sausage, 2 cans of pop (Coke or Ginger Ale), and a bottle of water. Please bring cash (but we can do debit if needed – no credit card).
Hope to see you out there – either in person, or, on the air!
So tonight we will have our first general meeting of the new club year 2018-2018!
As per usual – we will meeting at the south Fletcher’s Creek Sportsplex (McLaughlin and Ray Lawson in Brampton) at 7.30pm in the Craft Room.
We will be renewing memberships, reviewing club news and business (ARES Activities, Homebrew) and other upcoming events.
On the subject of memberships – a new convenience is being tested out this year. Many of you have taken advantage of being able to pay online. At the meeting tonight – if you havent paid yet, we will be able to accept credit card and debit payments (Done through Square Payments). If you can’t make the meeting, but want to pay online, and have not received an invoice – email me (kingpin (dot) joe (at) gmail (dot) com) and I’ll send you an electronic invoice that you can pay at home.
If you have any announcements you would like to make to the club, or would like to do a little bit of “show and tell” tonight, let me know!
