Guys, This afternoon, I received 20 values of capacitors (total 10,000 capacitors), and I spent about 3 hours to kit for 5 customers. I am pleased to see these shining new "Green Beans" will be

Guys, I will offer another assortment at the same price. Please contact offline. I have ordered the parts and will ship next Monday if everything is

Thanks for letting me know the values you are offering. None required at the present. John vo1jcc. Sent from Yahoo Mail for iPad

Would 10 each of these values good for you? I will ask for $5 for each set of total 100 pcs and the shipping cost would be $5 each

Hi Adam, Any chance you can send out Smaller quantities of monolithic capacitors. May need some later but not right now. John Vo1jcc.

Gang, Recently a famous QRPer in United States wrote to me looking for a good source of NP0 or C0G monolithic capacitors for VFO, and my recommendation is the light green capacitors that I have been

Way low. 6V PP translates to 4.242V rms (Vp-p*.707) across 50 ohms or .08484A (ohms law) and the power is RMS voltage * current or about .35W not the nominal 6-10W at nominal 13.8V. I'd expect the

Hi all, I finally got the bias voltage right ( had a shorted 3357 ), now , not having a rf meter for 20 meters, I hung a scope on the antenna. I could only peak for 6 volts p-p, all the 530 voltages

Hi Again, I was aligning the tx section of my rig and don't have a watt meter for 20 meters so I put a scope probe on the antenna, the envelope measured 6 volts p-p. Is that about right or do i really

Gang, As the year end comes, we will provide 8% off promotion for CS-series kit only from now on to the end of this year. Place online order through: http://crkits.com Thanks, Adam

I have now decided to make the faceplates for all three of these options available, LCD, Larger OLED and Small OLED display. The cost is $8 per plate plus shipping. Both front and back plates are

Here in the USA 9MHZ crystals are common. I've built many filter using them. however ladder filter like in KNQ7A and others will cave a center frequency slightly lower than 9mhz (using rocks that

The drain should be very near the power supply voltage if its dropping its either a problem with the meter going nuts from RF (They do that!) or your power supply is weak. The gate voltage for the

I did some more checking and changed the 510, the gate voltage goes to 2.2 volts on keying and the drain drops to around 10 volts all other voltages arereal close to the

Ron, Have you observed very hot parts during transmission? Besides the trimmer position, please check if you have properly installed the insulators for BD139/D882 and IRF510.

Hi All, Finally getting around to finishing my knq7, but ran into a problem. The idle current is around 40 ma but when PTT is keyed it jumps up to around 1400ma at the low end. Any ideas on where to

John, In old days, when SSB radio is homemade, 9MHz IF is used because 5.0-5.5MHz VFO can be used for both 20 meter and 80 meter bands. However, 9MHz crystal is not generally available, so nearby

Adam, The CS-Series is a great platform for learning and experimenting by changing a few components at a time just to see what effect it has. So I'm curious why 8.4672 MHz was chosen as the IF in the

Gang, I think everyone should be informed of this effort by JH3BTK. He did modification for JT-65 and FT-8 before and now he is supporting CAT for
