I bought the kit at the 2019 OzarkCon in Branson. It has BNC connectors instead of RCA connectors.

GA Ross,

yes, please! No, I don't have a set price. But I would rather buy a 5Watter and 2 QCX and a BitX20 for $ 250 than a OHR 500 for $ 250. More bang for the buck kinda thinking.

Hi All

greetings from Dhaka. Most ops have a Chinese made H-T. HF is rare and I only found a single CW op, who has been living imn Finland.

- Hilltopper 20 (if no one sells it, when can we expect for it to besold again)
- a 40 m Receiver - you guys used to sell one.
- QCX transceiver & '5Watter' (40 or 20 for both)
- SSB transceiver, be that a BitX20 or something which is good.

CONUS shipping and I do have Paypal and through a friend, an online payment could be arranged, too.

Am hoping for a fair deal as the local guys are usually struggling financially (many are freelance engineers). No, few are on the normal $ 2 a day salaries paid in the textile industry. https://www.youtube.com/watch?v=6Y9UaLKbZQ0

The facts:
First, and most importantly, the receiver opens with the no 75 message and defaults to the frequency. Unfortunately, it only tunes 3.839 to 3.840 (the default frequency) and no other frequencies. I cannot select any other frequency.
Second, depressing the tune button does not dim the display (not a big concern) but it does allow me to bring up the 1.901 or 1.902 setting. 
Third, the LED does dim with a strong signal present as from a signal generator.
Fourth, I do have audio from the speaker and headphone jack. 
My question is what may be the cause of limited frequency selection?

Re: QRPoMeter

nm0s_qrp <ai9e_qrp@...>
 

So the important question is, do you have a new (NM0S) kit, or an old (4SQRP) kit?  The 4SQRP kits came with RCA connectors.  The old kit used ceramic monolithic capacitors, and included an 0.001u for C3, while the new kits use ceramic disks, and C3 is 0.1u.  The instructions are very different between the two versions.

I think I found it....google search for Qrpometer Docs came up with this  http://www.4sqrp.com/kits/QRPometer/qrpometermanualv4.pdf

From 2012....C3 is listed as .001 and marked as 102.

He may be using an old doc?  Or maybe he has an old kit?

Nice job Robert!  I too have a 3D printer (in fact I have 2 of them).

Thanks to K8IQY's tutelage, I've gotten to the point I can design stuff like this using Fusion 360.

Currently working on cases for the QRP-Labs clock kit.  Lots of fun.  I'm 77 so you have a few years on me hi hi.

I have the smaller KX2 so your rack wouldn't fit but I may have to work on something similar to fit it and still allow the use of the built-in paddles.  Thanks for sharing this.

Re: QRPoMeter

Todd Carney <carneytf@...>
 

Just a bit more on these two caps. The one from your junque box (and on the left in your picture) is probably a MLCC (Multi-layer ceramic capacitor). The one on the right in the photo is a "legacy"-type ceramic disk (most likely single layer). Other factors the same, MLCCs are smaller than single-layer caps.

Another important factor with ceramic caps (all caps, really) are the characteristics of the dielectric--the non-conducting material between the "plates" (layers) that form the capacitor. An important characteristic for RF work is the temperature coefficient ("TC"--change in value per degree of temp change) of the dielectric. Whether or not this is important depends on the function of the cap in the circuit. If the cap is being used for RF coupling or bypassing, drift in value due to temperature change is far less important (often totally inconsequential) than a capacitor used in RF frequency-determining parts of an oscillator or filter. Caps with X5R or X7R (the most common general-purpose types) are generally used for coupling and bypassing and for that purpose are made in the higher end of the range of values (for ceramic caps, anyway).

Your 0.001uF cap (and most caps spec'ed in uF) is an example. Caps valued in picofarads (pF)--especially in small values--are usually used in frequency-determining parts of a circuit and their TCs can be critical. For ceramic caps, the NP0 (negative-positive zero) types are far-more stable than the more common X5R and X7R types.

For a really thorough and well-illustrated (but still accessible) article on ceramic capacitors, see https://en.wikipedia.org/wiki/Ceramic_capacitor. It's really quite fascinating (but I'm a nerd, so . . . )

I'm building the QRPometer kit and I ran into a minor problem. My kit did not have the C3 capacitor. The C3 cap has a value of 0.001 and has the number 102 stamped on it. In my junk box, I found some caps that have the same value and the 102 stamped on it but it is a little different than the ones that come in the kits.
 
The capacitor on the left is the 102 capacitor that I had in stock. The one on the right is an example of the caps that came in the kit. So I'm wondering if it would be ok for me to use the cap that I found since it has the exact values as the one that is missing in the kit.
