Jack and ...., I tried adding a fan very similar to the one pictured and it introduced a "whirring" noise into the audio that I could not get rid of. It was wired up to the main supply voltage via the

Last time I ordered from them I made the money order out to “Dan’s Small Parts and Kits” Mike K5ESS Sent: Thursday, June 01, 2017 1:45 PM To: [email protected] Subject: [BITX20] question about

Almost the same here, loads of spare connectors from previous projects, and a spare microphone. Result... no outlay for new bits. More to spend on strip board and knobs etc. Phil - G7BZD

I really should have updated this thread. I have gone a different direction with the mic. I built one from scratch, and it's worked out nicely. I used 8 pin mic connectors because I got 5 of them for

You make it out to Dan's Small Parts and Kits. Have ordered from him numerous times. Also see?http://stores.ebay.com/twisttwinkel ( http://stores.ebay.com/twisttwinkel )?his online ebay store.

GM - I am putting together an order to send to Dan's Small Parts in Montana. Per Dan's instructions, I am sending a USPS money order. Does anyone here know to whom the money order should be made out?

I have a 60mm PC fan in my holiday tin enclosure without vents. I use the separate PA power input with a step down buck converter to power the fan without the noise you get when tapping into the main

Reformatting makes it easier to read. diff -b ignore changes in white space. But I don't plan on messing with the Raduino code. I'm in the process of writing one myself. Vince - KA8CSH -- Michigan VHF

Frustrating. I did find several listings on eBay if that is suitable. All located in China however so subject to several weeks wait for shipping http://www.ebay.com/itm//121792606612

I tend to agree with Bob. ? But Allard is doing a great job in getting that firmware sorted out, and I'm looking forward to seeing the end result of his process. I've been kibitzing now and then as

Yep, I do think that's better. BTW, I think I'm going to add a 25mmx25mm mini fan to the back of the case right behind the PA. (See picture.) My enclosure doesn't have any airflow, so I found these

Pins 1, 7, 6, 5 are all that needs connecting, I too use the HM-36. Phil - G7BZD

I'm waiting for a small adapter PCB that one reader is making for converting a Type I to a Type II footprint. Even if it costs $2-3 it's still cheaper than the Type II. I'll post when I find out about

I wondered when you were gonna ask me to dance again Jack. You're absolutely right. I should have gotten information about the Arduino Nano used on the Raduino board. So here it is.- Power The Arduino

I used a circuit that is similar to the one in the QEX article, but using a JFET (MPF102) instead of the PN2907/2N7000 combination. This circuit has been around a long time and can be found in several

The schematic agrees with how the board is built, so the schematic should remain as it is. But I agree with K7IOW, looks like an error to me, and that the intent was to wire up K1 same as K2. Could

Hi Allard, There may well be reasons that you prefer TX Offset which I don't appreciate (like memory size), but it really should be a RX offset. Here's a final example. Say that WB4SON has been

Hi again, I checked with the seller of the board. The listing said will not ship to Canada. However he did say he would send one by FEDEX for $20 USD or DHL for a bit over $25. I've been stung by

I like Raj's 0.1uF fix, very simple and elegant. ?Oh, and very cheap. Could add a jumper across it when operating CW. Also, remove a new jumper that supplies power to the mic amp, not needed for CW.

just 2 picture of how my Bitx40 look, 1 from front panel and 1 show the inside ! work to do....attach speaker to box and place a 7809 before Raduino to cool it down and remove tuning clicks
