The key clicks seem to be getting worse and worse. This year in the CQ 160 contest, there was one station who could be heard most of 5KC with his FT1000D. Several others using Yaesu radios were also
Think probably has a good deal less to do with the exciter than how the amplifier is driven. Particularly those amps that need only 65 watts to drive it to 1.5 kW. The loading needs to be backed off
After using the new Timewave filter at K5KG's QTH last weekend, most loud signals appeared to have clicks. It was very annoying. I don't notice the same phenomena on my 'MP with INRAD filters. Is it
I might suggest this is more a phenomena of signals being loud in Florida and weak in western W7. 73 Bill -- CQ-Contest on WWW: http://lists.contesting.com/_cq-contest/ Administrative requests: cq-co
I agree with you, Bill. Have noticed same thing re lots of clicks on the bands during contests, thought it was just me, though. I run my MP with about 15-20 db of Attentuation, i.e., helps me when wo
I think it's more likely that the MP receiver can't handle lots of strong signals in the wide passband of the early stages. This could be true of other "state-of-the-art" radios, too. Up until this w
Hi Bill and all, I've been watching this for a while and keeping a list, and it isn't just the MP's that are problematic. The 775DSP's are particularly bad for spurious signals, thumps, and clicks. I
Are there any reports of this type of Receiver issue in the new FT-1000MP Mark 5? Thanks... Rich I think it's more likely that the MP receiver can't handle lots of strong signals in the wide passband
Unless you have a malfunction, your MP is clean, check the Radcom and QST reviews. Either way you cannot, unfortunately, alter the keying characteristics of the MP( et al) the way you used to be able
Hi Dick and all, If this is too long, skip to the end. I have a constructive suggestion that might be fun and educational. Most radios fall apart somewhat at close spacing. The ARRL announced on the
Hi Clive, I hate to bring bad news, but..... I have no idea what RADCOM measures, but QST reviews do not measure CW bandwidth.... nor do they measure SSB bandwidth with valid modulation envelopes. Pr
M Adding less than $1 worth of parts I significantly improved the closespaced performance of my FT-1000D. It seems design-care rather than cost is behind less than state-ofthe-art performance. TOM :
I guess I'm missing something. According to the Handbook, key clicks are a consequence of the rise and fall times of the transmitter's output, and that the tailoring of these times is a design choice
The "clicks" are not necessarily related to problems with they keying waveform in some "modern" transceivers. If their synthesizers do not stabilize BEFORE the production of RF (a very real possibil
Would it be feasible to use the same test setup that ARRL uses for composite noise, but key the transceiver at a standard rate, both with and without a standard transmit/receive offset, and look for
Would it be feasible to use the same test setup that ARRL uses for The problem is to measure bandwidth the analyzer must have a much narrower filter than the bandwidth you are looking at. So if you w
